A Short Commentary on the NIV Bible.

My Largeprint NIV 2011 (Anglicised)Reference Bible.

‘The days are coming,’ declares the Lord,
    ‘when I will raise up for David a righteous Branch,
a King who will reign wisely
    and do what is just and right in the land.
In his days Judah will be saved
    and Israel will live in safety.
This is the name by which he will be called:
    The Lord Our Righteous Saviour.

                                                                                    Jeremiah 23:5-6

Preamble

There’s an old Chinese saying, “May you live in interesting times.”  There’s no doubt that we do and then some. At a time in history when humanity is at its most creative, its most technologically advanced, a time when scientific knowledge has been increasing exponentially, it is also a time when mankind has begun to unhinge itself from the timeless truths and morals rooted in the Judeo-Christian faith, which held much of the western world together through a common culture and creed for centuries and millennia. Church attendance began to decline in the mid-20th century, slowly at first and then more rapidly, when in the twenty first century, many of these beautiful and age-old centres of Christian worship have been transformed into pubs, restaurants and nightclubs. This is part of what the Bible calls the ‘great falling away,’ where the end of days is characterised by a small, healthy, recalcitrant Church of true believers walking the narrow path, loyal to God’s unchanging message. I believe these trends to be no accident; this falling away was augured from the foundation of the world.

Deceived by silver-tongued atheist evolutionists (read fools) who disseminated their godless(and false) ideologies in best-selling glossy books and prime-time television documentaries proclaiming that we’re not made in the image of God, as the Bible uniquely attests, and that we are only highly evolved animals, our morality was destined to take a steep nose-dive. Abortion, once outlawed in all civilised nations is now fair game in many of the same nations, where today it has become the leading cause of death in the west, outstripping heart disease, cancer and diabetes. The same is true of homosexuality. Scarcely a quarter of a century ago, surveys consistently showed that the vast majority of people were firmly against it on moral grounds. Today, as activists in positions of power have lobbied(I would say bullied) our governments to normalise it, it’s now all over our television screens – morning, noon and night. And while one or two per cent of people identify as such, I find it truly alarming that nearly every second programme beamed into our living rooms has a theme or story related to these deviant sexual lifestyles. What’s more, for a career in modern showbizz, being openly gay has almost become a prerequisite!

So I don’t watch TV anymore and carefully vet all programmes my kids choose to watch, lest their minds be caught up in this campaign for immorality.

Men are now marrying men, and women do the same. They are raising children in homes where the traditional roles of father and mother are no longer considered important. With single-parent families now the norm, children grow up without the steadying influence of a mother or a father. Small wonder so many of our little ones grow up confused. And if the present trends in society are anything to go on, polyamory will become widespread and bestiality will also be normalised.

Our entertainment industries; Hollywood, sports, gaming and pornography, take centre-stage in many of our lives and have done much to erode traditional Christian moral values. Our children learn to kill efficiently and mercilessly with their joysticks, the films they watch are filled with gratuitous violence, infidelity, and blaspheming. Pornography is ubiquitous, tearing families apart. Our sports men and women and other types of celebrities have been elevated to the status of idols and we’re on our iphones more or less constantly, bombarding our senses with as much meaningless drivel as we can possibly soak up. Instead of seeking the true God, we lose ourselves in drug-induced trances. Who needs God when you have alcohol, cannabis, heroin, crack cocaine, crystal meth and so-called ‘prescription drugs’ to dope you into a false utopia?

While childhood used to be a relatively happy and carefree time of life, our young ones are now sexualised to the hilt. Indoctrinated by depraved activists with no respect for traditional values about gender or the family, the number of children receiving puberty-blocking drugs has skyrocketed in recent years, as has the number of teenagers and adults undergoing transgender hormone therapy and/or surgery. And yet, all the while, there has been an avalanche of such transgender individuals reporting that they regret undergoing such life-changing therapies, triggering severe depression in many cases and a commensurate rise in suicides among their members. This only serves to reveal the truth in all of this; transgenderism is a mental disorder, pure and simple, and many clinicians working in the field would agree with me.

With increasing wealth comes increasing materialism. We have larger disposable incomes than at any other time in human history, and yet our propensity for greed spirals ever upward and out of control. The ugly sceptre of human covetousness has led to great deteriorations in the salubrity of the natural world, with the collapse of whole ecosystems, the decimation of animal and insect populations, and all-out extirpations of hundreds of land-based and aquatic species. Without a shadow of a doubt, humans have proven to be irresponsible stewards of the planet and we won’t be given another one.

Many forms of counterfeit Christianity have emerged in recent decades. False  teachers are a dime a dozen and very effectively disseminate their lying doctrines to their sleepwalking congregations, who have ever shorter attention spans and who resent being challenged or rebuked. Whatever you believe, however unscriptural it may be, you’ll soon find a pastor willing to tickle your ears. The internet is crawling with them!

Curiously though, all of this has occurred in lock-step with increasing knowledge of our significance in the Universe. Naive and ill-thought-through faith in Darwinian evolution led many scientists to suppose that extraterrestrial life would be the rule rather than the exception. But we are now more certain than at any time in the past that our planet is extraordinarily rare, if not unique in the Universe, and that all terrestrial life is far too complicated to have evolved naturally from the everyday laws of chemistry and physics that govern everything else in the inanimate cosmos. No, life comes from the mind of God. To deny this fact is sin. Life on Earth is God’s ‘Ace card,’ and human life His Royal Flush. We ain’t going anywhere either, to the chagrin of space-age dreamers. With the possible exception of our nearby Moon, humans are unable to travel and live on other worlds. The reason is simple; our physiology precludes it.

Lawlessness has greatly increased in recent times, with hardly a day going by before we hear of another terrorist strike, protest or war breaking out. The victims of these conflicts are usually the ordinary citizens, leading to the destruction of their homes, their places of business and worship and their livelihoods. Millions of people have been displaced from their homelands, creating the largest humanitarian crisis in living memory. Christian persecution worldwide has also greatly increased in our times. Coupled to all of this, the events surrounding the prophecies of Ezekiel (Chapters 36, 37, 38 and 39) are now aligning themselves in the Middle East. You simply couldn’t make this stuff up!

The bubble has truly burst!

Bearing in mind how human society has changed in recent years, would it be unreasonable for God to express His displeasure with us?

I don’t think so!

This pandemic is a chastisement from the Living God.

The Bible informs us that God expresses His indignation with His human subjects in a variety of ways; by sending freak weather – fires, floods, droughts and blizzards as judgements. He sends plagues, pestilences and earthquakes which, like Sun and rain, affect both the righteous and the unrighteous. He turns the wicked over to strong delusion so that they wallow in their lies and seared consciences. And yet, Jesus warned us that as humans become more wicked and depraved, all of these events would increase both in magnitude and frequency, just like birth pains, toward the time of the end. And this is the world we now inhabit. In one fell swoop, by allowing(but not causing) the spread of the Coronavirus, God has silenced the idols of Hollywood, the idols of sport, and the idols of health, wealth and prosperity. He has restricted our freedoms and our civil liberties.

God now has our undivided attention and the world would do well to listen. Perhaps most importantly, God is reminding us not to get too caught up in the cares of this world and that this is not our ultimate home. Everything we possess and covet will be burned up when God finally brings this Universe to a fiery end.

Of course, none of these trends come as a surprise to Bible believing Christians, who have been forewarned about them in the words of Scripture. Christians know and understand that the world ruled by man, with no regard or acknowledgement of the Creator, is doomed to failure and always goes from bad to worse, so that it is hardly surprising all of these events are converging in this day and age. And while I’m confident that we will get through this Coronavirus pandemic, there will certainly be other and possibly bigger challenges to come, especially if wider society does not repent.  It also highlights the importance of understanding what God has planned for his people, and one of the best ways of gleaning that information is by reading the Bible.

Background to the NIV

Necessity, they say, is the mother of invention, and in the case of the New International Version (NIV), it was born out of a desire to share the gospel with those who had never heard it. It’s story began with one man, Howard Long, an engineer by profession based in Seattle. Possessing a strong Christian faith, Long spent a lot of his time travelling and liked to share his faith with others. Back in the 1950s, there were only a few Bibles penned in the English language, but the one most popularly used by evangelical Christians at that time was the old King James Version(KJV). But Long soon hit a snag; quite a few of the people he witnessed to didn’t really understand the KJV, as it was written in archaic English. And that got him thinking, “can a new translation be made of the Bible in contemporary English that accurately conveys the Word of God?” That question started a decade long consultation with Bible scholars across the nation and by 1965, he had successfully received support from the Christian Reformed Church and the National Association of Evangelicals, who set up a new committee that would begin work on a brand new translation of the Holy Scriptures that was not based on any other existing translations at the time, and which would draw upon the latest Hebrew, Greek and Aramaic manuscripts. By 1966, Long had successfully garnered the support from 80 evangelical ministry leaders who established the Committee on Bible Translation (CBT), an independent body overseeing the creation of the NIV.

Thus began the painstaking process of creating a new English Bible translation with the goal of attaining maximum accuracy and readability for a contemporary audience. Each book of the Bible was assigned to a translation team consisting of two translators, a couple of translation consultants and, where necessary, an English style consultant. Furthermore, another 5-strong team of scholars reviewed their work, comparing it to the original biblical texts and assessing its readability. After that, each book went to a committee of between eight and twelve scholars, as well as lay reviewers who offered constructive criticism on the translation in regard to comprehension and overall literary style. Finally copies were dispatched to working pastors, students and members of church congregations for general feedback. By 1968, the CBT secured a financial sponsor in Biblica, who oversaw the development of the NIV text, and by 1978 Zondervan became the official publisher of the newly completed NIV Bible. The first print run – amounting to a million copies – was sold out almost overnight.

The NIV was the first to use gender inclusive language, recognising that older translations tended to use male biased terminology to reflect the culture in which the Scriptures were first penned. An example can be seen in 1 Thessalonians 2:1. Here is how the KJV reads:

We beseech you, brethern……….

And in the NIV :

You know, brothers and sisters……………

The aim of the translators in producing more gender inclusive language was to make it more accessible to a female readership. In most cases, these changes are entirely inoffensive, as they do not detract from any doctrinal issue and render the text more natural sounding to a modern reader who accepts the equality of men and women as children of the Most High. But in other passages the use of gender inclusive language renders the translation somewhat corny or awkward. Take Mark 1:17 for example. In the KJV it reads:

I will make you to become fishers of men

Note how the NIV phrases the same passage:

I will send you out to fish for people

The NIV underwent its first revision revision in 1984. This version is probably the highest regarded among Bible readers and remains a firm favourite with a broad section of Christians. But in 2005, more revisions were introduced including the highly controversial Today’s New International Version (TNIV), which introduced gender neutral language to refer to people. Noting the tendency of older versions to translate humanity as ‘Mankind,’ the TNIV replaced many of the passages emphasising overtly male-centred language. An example will help illustrate the point.

Here is how the 1984 NIV translated Genesis 1:27

So God created mankind in his own image

The TNIV translates the same passage as:

So God created human beings in his own image

Many Bible commentators felt that this was a step too far, as it sought, they argued, to make the Bible more ‘politically correct.’ Taking these criticisms on the chin, the CBT brought out a new version of the NIV, discontinuing both the 1984 version and the TNIV. Called the NIV 2011, it toned down a lot of the gender neutral language introduced by the TNIV, making it more similar to the NIV 1984. Indeed the CBT stated in the introduction to the 2011 edition that, “the updated NIV you now have in your hands builds both on the original NIV and the TNIV….”

Strking a Balance Between Two Translation Philosophies

Unlike old Bibles like the KJV, which drew upon a relatively small number of newer manuscripts( 12th century and younger), 100+ bible scholars working on the NIV included the Dead Sea Scrolls (which featured a number of Old Testament books), the Masoretic Hebrew Texts (which are the authoritative Hebrew scriptures, featuring 24 books of the Hebrew Bible), the Samaritan Pentateuch (the first five books of the Hebrew Bible attributed to Moses), the Latin Vulgate (a 4th century Latin translation made by St.Jerome that remained the official Catholic Church’s Bible for many centuries), to name but a few. All of these manuscripts were thoroughly read, translated and brought into modern English.  The translation process was long, thoughtful, and in-depth.

Some critics of the NIV have stated that many verses have been left out or placed in footnotes when compared to translations like the KJV, the New King James Version(NKJV) and the newer Modern English Version(MEV). But The CBT were justified in doing so as many of the older manuscripts discovered in the centuries after the KJV was created do not contain such verses. The decision to do this was not at all intended to deceive, as some Bible commentators I’ve read have suggested but rather to clarify them as facts. For example, the ending of Mark’s gospel is presented in italics with a heading stating that, “the earliest manuscripts and some other ancient witnesses do not have verses 9-20.”

The ending of Mark’s gospel (chapter 16) in the NIV 2011 is presented in italics to emphasise the fact that many of the oldest manuscripts did not contain such verses.

A curious aside: Check out this youtube link to an NIV user who was villified by KJV onlyists. Such bigotry is, unfortunately, still alive and well today

……………………………………………………………………………………………………………………………..

Most modern Bible translations draw on one of two translation philosophies; so-called ‘word-for-word’ and ‘thought-for-thought’ (sometimes referred to as dynamic equivalence) The KJV, NKJV, MEV and New American Standard Bible(NASB) and the English Standard Version(ESV) are highly literal, word-for -word translations, but many readers, especially new Christians, find them to be difficult to read and understand. The NIV is a thought-for-thought translation, and so often departs from the precise wording of more literal Bible translations in order to convey the essential concepts more firmly.  That said, having read the NIV 1984, TNIV and the NIV 2011 in their entirety, I would say that all achieve a very high level of technical precision yet are easy to read. The language of the NIV is at a grade 7 level and so is suitable for all readers 12 years old and upwards. In regard to reading through the NIV 2011 in particular, I found it to be very enriching experience. And while it is a new and fresh translation, it is obviously respectful of classic translations like the KJV. The poetic sections of the NIV Bible, particularly the Book of Psalms, is arguably one of the best presentations I have personally encountered.

As an avid reader and collector of different Bible translations, I recognise the value of every version. What may be unclear in one rendering of the Word of God, other translations can help you arrive at a crystal clear understanding of the same text. Crucially though, the NIV, like all other modern English Bible translations, there is no change in doctrine between them. So you can be assured that in reading the NIV you will arrive at an accurate understanding of God’s message to humanity.

There has never been a better time to get back into reading the word of God, and the NIV 2011 is a great, scholarly translation that is both accurate and easy to read. But I would also recommend reading another more literal version of the Bible as well if you can. As world events continue to unravel before our very eyes, knowledge of the Bible will help you see the wood for the trees, so that you’re not frightened or caught off guard when disaster strikes. Time spent reading and applying Biblical wisdom will be added to your life.

Postsciptum:

The NIV is also available in both American an anglicised (UK) English

The NIV has also been translated into many other languages to reach millions of non-English speaking people around the world.

Like all good Bible translations, the entire text of the NIV can be accessed free online.

There are audio versions of the NIV available. Arguably one of the best is narrated by the actor and Christian, David Suchet.

A Brief Look at The New American Standard Bible (NASB).

Arguably the most technically precise Bible in existence today: the author’s copy of the NASB (1995  edition).

Therefore everyone who confesses Me before men, I will also confess him before My Father who is in heaven.  But whoever denies Me before men, I will also deny him before My Father who is in heaven.

Luke 10:32-33

Today we are most fortunate indeed to be the beneficiaries of wonderful Biblical scholarship that dates back five hundred years or more. Such diligence has produced a number of highly accurate translations of the Old and New Testaments in the English language, with the Authorized King James Verson(KJV), the New King James Version(NKJV) and the English Standard Version(ESV) representing just three of the best word for word renditions of the Holy Bible. As a keen reader of Scripture, I am always on the look out for new ways to improve my personal knowledge of the Bible, and, in this capacity, found yet another version to be particularly enlightening; enter the New American Standard Bible(NASB).

Like so many highly literal versions of the Bible, the NASB has an interesting history. Beginning in the 1880s, a team of American and British Bible scholars embarked on an ambitious project to update the archaic language of the KJV, producing the English Revised Version, which in turn formed the basis of the American Standard Version(ASV), first published in 1901. The ASV called upon a much larger number of manuscripts than the prestigious KJV, which were considerably older than any of the sources used to construct the KJV(mostly 10th and 11th centuries AD). And it was about this time that scholars began to notice a few small differences between the older and newer manuscripts. An example can be found in the Gospel of John chapter 5:

The KJV reads:

For an angel went down at a certain season into the pool, and troubled the water: whosoever then first after the troubling of the water stepped in was made whole of whatsoever disease he had.

John 5:4

Once manuscripts dating back to the 4th and fifth centuries AD began to be uncovered, it was noted that many of them did not contain this verse, suggesting that it was accidently inserted by scribes at some later time. That is why most modern Bibles have a footnote at John 5:4 which says, ” older manuscripts do not contain this verse.”

And yet, here’s how the NASB deals with it.

 

]for an angel of the Lord went down at certain seasons into the pool and stirred up the water; whoever then first, after the stirring up of the water, stepped in was made well from whatever disease with which he was afflicted.]

John 5:4

So the NASB committee decided to leave it in……with a bracket around it.

 

As Biblical archaeology unearthed more and more ancient manuscripts throughout the 20th century, culminating with the astonishing finds contained in the Dead Sea Scrolls, which were unearthed in the Qumran Caves in the Judaean Desert between 1946 and 1956, many Bible scholars felt it was high time that a new translation of the original Hebrew and Greek tongues be constructed which benefited from these new insights. Thus, in 1959 work began on a new translation which honoured both the ASV and KJV under the aegis of the Lockman Foundation, which called upon an international team of Bible scholars and pastors from a broad cross-section of denominations to create the New American Standard Bible (NASB), which say first light as a complete work in 1971. Another revised NASB appeared in 1977(still with the old ‘thees’ and ‘thous’)  Still, as good as the original NASB was, an updated and improved version of the NASB appeared in 1995(with the ‘thees’ and ‘thous’ were modernised). This is the version I wish to discuss in this blog, though it is understood that the Lockman Foundation is currently at work producing yet another updated version of the NASB, which will appear in print in 2020.

Some Unique Attributes of the NASB

One of the first things you will notice when you start to read the New Testament in the NASB is that it highlights quotations or citations from the Old Testament in small caps. Consider 1 Peter 3:14-15

But even if you should suffer for the sake of righteousness, you are blessed. And Do Not Fear Their Intimidation, And Do Not Be Troubled, but sanctify Christ as Lord in your hearts, always being ready to make a defence to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence;

1 Peter 3:14-15.

The small caps, ” Do Not Fear Their Intimidation……”  immediately informs the reader that this is a direct citation from the Old Testament, specifically Isaiah 8:12, but if you were reading the much more popular ESV  Bible, for example, you would never know this, since the same text is not presented in small caps. In line 3 of the above Scripture,  you also see the word, “being,” is presented in italics. This indicates that the same word is not found in the original Hebrew but was an educated guess(based on the context) by Biblical scholars to render the implied meaning as accurately as possible in modern English.This comes with the territory in any endeavour to translate one language into another.

In this way, I feel the NASB gives proper due respect to the words of Scripture, showing the reader where Biblical scholars have given their interpretation of the text in contrast to many more popular translations where such wording is not highlighted and so the student is left none the wiser.

In studying the NASB New Testament I have also come to appreciate Jesus’ own knowledge of the Old Testament. While many liberal scholars erroneously avoid prophetic texts such as Daniel and Ezekiel, the NASB reminds the reader that Jesus knew and believed on these writings, using them to assert His own position:

So He was saying, “What is the kingdom of God like, and to what shall I compare it? It is like a mustard seed, which a man took and threw into his own garden; and it grew and became a tree, And The Birds Of The Air Nested In Its Branches.”

Luke 13:18-19

The small caps indicate that our Lord was quoting directly from the Book of Ezekiel (see Ezekiel 17:23), the prophet and priest who was taken into captivity in 597 BC during the second deportation which was imposed on the Jewish leaders and aristocracy by their Babylonian overlords.

Or consider Matthew Chapter 24, when Jesus clearly identifies Himself as the returning Messiah;

And then the sign of the Son of Man will appear in the sky, and then all the tribes of the earth will mourn, and they will see the Son of Man Coming On The Clouds Of The Sky with power and great glory.

Matthew 24:30

The small caps in this tract is a citation from Daniel (see Daniel 7:13).

The many Christian denominations that avoid such books are, in a very real sense, depriving their congregations of the importance Jesus placed in these writings. The words of St. Paul seem especially prescient here;

How then will they call on Him in whom they have not believed? How will they believe in Him whom they have not heard? And how will they hear without a preacher?

Romans 10:14

Yet another feature of the NASB 1995 edition is the use of capitalised personal pronouns properly ascribed to deity;

God said to Moses,”I AM WHO I AM”: and He said, “Thus you shall say to the sons of Israel, “I AM has sent me to you.’ ”

Exodus 3:14.

Many Bible commentators have expressed the opinion that compared to other good word for word translations of Holy Scripture, the NASB reads and sounds a bit “wooden.” I understand this position, as the NASB can indeed come across as a bit awkward and hollow in places, but this was deliberately done so as to maintain the highest degree of one-to-one correspondence with the original tongues. And while no translation of the Bible in English can be said to be wholly word-for-word, since this would make the text essentially unreadable, I have personally appreciated the strident efforts the NASB translators made to anchor their choice of words in the original texts. On my own personal journey studying God’s word, I have come to admire the academic excellence that went into creating the NASB, as it was a thoroughly enriching experience, and look forward to seeing the new edition when it finally becomes available. It will not replace my personal favourite translation, the NKJV, for general use, but for serious study, the NASB will most certainly be top of my list.

A Few Examples of NASB Bibles

Good quality Bibles don’t need to cost the Earth. I personally avoid overly ornate Bibles as they are largely impractical to use on a regular basis and my rule of thumb is simple; if the Bible is too beautiful to soil, don’t use it.

That said, like many of the more popular translations, the NASB comes in a variety of convenient forms. For example, below is shown a compact large print edition of the NASB with the words of Christ in red. The cover is synthetic (leathertex) and has a lovely gold gilding as well as a smyth sewn binding:

My eldest son’s compact, red letter edition NASB.

My own personal NASB is also a 1995 edition, with a good, large font size, and wide side margins replete with copious cross-references for in-depth study;

It is not a red letter edition, but does have an 82-page concordance and a series of full-colour laminated maps of the Biblical world. The print quality is very good, with adequate line matching, although some ghosting is apparent. The 833W volume has a durable leathertex cover with a paste-down lining. It also has a good Smyth sewn binding and a beautiful gold gilding but only comes with one ribbon marker. It was not expensive.

I am also fortunate enough to own an excellent NASB study Bible which I actually acquired second-hand. It is published by Zondervan.

The Importance of Remaining Anchored in the Word

The modern world is rapidly unlocking itself from Judeo-Christian values with disastrous consequences. Ironically, even outpsoken atheists are increasingly expressing the same concerns. Morals and values we held as ‘self-evident’ for centuries and millennia are no longer adhered to, and the consequences are all too easy to see; just look at the confused and depraved world we now live in. That is why remaining anchored in the inspired word of God is more important now than at any other time in history. Its wholesome words ground you in absolute truth and is an enduring source of comfort in a lost and dying world.

The prophet Isaiah writes;

“For My thoughts are not your thoughts,
Nor are your ways My ways,” declares the Lord.
“For as the heavens are higher than the earth,
So are My ways higher than your ways
And My thoughts than your thoughts.

Isaiah 55:8-9

Ultimately it’s a choice everyone needs to make. I pray that those reading this will not end up on the wrong side of history!

Eternity is an awfully long time!

Some Comments on the New Living Translation(NLT) of the Holy Bible.

The NLT Large Print Thinline Edition.

And now, dear brothers and sisters, one final thing. Fix your thoughts on what is true, and honorable, and right, and pure, and lovely, and admirable. Think about things that are excellent and worthy of praise.

                                                                                            Philippians 4:8 (NLT)

Preamble

Take a good look at the world around you.

Lawlessness is on the increase in every nation. Our TV and cinema screens are cesspits of filth, lewdness, blasphemy and the glorification of violence. Britain is now the stab capital of Europe. Anti-semitism is escalating across the globe, tearing whole communities and political parties apart. The cold-blooded murder of the unborn is legalised in most developed countries and soon the right to life will be denied to the newborn(it’s already happened in fact). Traditional family values have all but disappeared. Our churches are nearly empty, their elders, priests and pastors, feverishly busy spreading false doctrines. Depraved acts such as homosexuality(they have the audacity to call it ‘sex’) are being promoted as ‘good’ and ‘natural.’ Our children are being taught that they are ‘highly evolved animals'(based on Darwinian pseudoscience); gender is ‘fluid’ even though our chromosomal karyotype plainly says otherwise, boys can be girls or vice versa, and morals are ‘relative.’  Wars and rumours of wars are never far from the headlines. The Middle East is a tinder box ready to explode. Civil war threatens many nations. Whole economies are collapsing. The rich are getting richer and the poor are getting poorer. Steeped in debt, young people can’t afford to get on the housing ladder. Homelessness is at an all-time high. Our once clean cities are slowly becoming slums. Food banks are now common across the western world and their queues are getting ever larger. The biosphere is dying before our very eyes; insects, animal and plant populations are being decimated by pollution, unsustainable and aggressive agricultural policies, and climate change.The bountiful seas are becoming water deserts. And there’s no where to go.

Don’t you think something is terribly wrong with the world? Are you not concerned for the next generation( if the Lord tarries) who will see these trends continuing to escalate?

You’re either a fool or completely deluded to think otherwise!

This is just the tip of the iceberg, of course, and I could go on and on.

What source of knowledge brings all of these evils into sharp focus?

Only the Bible provides the answers we so desperately seek. Moreover, it makes it pretty clear that it can’t and won’t be sustained.

The Bible warns us not to turn to idols(which includes atheism) for solutions. In the days of old, these took the form of carved images of wood and stone, animals and even persons( e.g. the Emperor Cult of the Caesars). And though the old gods are long gone, new ones have stepped in to fill the power vacuum; unaware AI, non-existent alien intelligences, sports personalities, rampant consumerism and greed (which the Bible teaches is yet another form of idolatory), ‘mind and body’ gurus, tree huggers and charlatans that promise the earth, steal your money, and leave you high and dry. The secular world believes man is benevolent by nature and can find the answers to all his problems, but let’s be honest; that humanist philosophy has failed miserably. Where exactly is that utopia you dreamt up in your vain maschinations?

It doesn’t exist and cannot exist.

In contrast, the Bible says precisely the opposite; left to his own devices, man is fundamentally not good. Humans become more depraved, more wicked and more desperate without guidance from their Creator. Without God in their lives, things always go from bad to worse. And the inspired Biblical writers foresaw all of it!

We need the Bible more so now than at any other time in human history.

How do I know this? I read the Bible every day. I see it all on the pages of Scripture, as if it’s today’s news. The secular world will accuse you of ‘bigotry’ and ‘small mindedness’ of course, for the simple reason that the same people are woefully ignorant of what the Bible actually says; not the watered down sermons you hear in a typical church on Sunday morning, delivered by a clergy that are increasingly afraid to offend anyone, but by taking heir of one’s self, and actually reading the Biblical text through and applying its principles in every day life. Seen in this light, the accusations of the secularists against true Christians are just more of the same: arguments from ignorance.

And that’s true bigotry!

There is a simple principle I apply in my dealings with the secular world: if it is approved of in the Bible, I’m for it; but if the Bible disapproves of it, I’m not for it!

It’s simple, straight-forward, and unambiguous.

In the 21st century there is an explosion of Bible versions written in the English language to suit the needs of a diverse group of people. The following diagram gives you an idea of the types of Bibles you can choose from:

The green zone represents very literal ‘word for word’ translations from the original Hebrew and Koine Greek. The orange zone represents an entirely different translation philosophy; the so called ‘thought for thought’ translations. Finally, the red zone represents the most loosely rendered interpretations of the Biblical text; the paraphrases.

As you can see from the diagram above, the New Living Translation(NLT) of the Bible is in the orange zone, so bordering between the ‘thought for thought’ and the ‘paraphrased’ renditions. But unlike true paraphrased versions like the Message or The Living Bible, the NLT is actually a true translation of Holy Scripture, but it places a great emphasis on rendering the essential ideas in simple, modern English. The NLT was formulated by a broad church of Christian denominations under a solid translation committee. This is evidenced by the lack of errors in the text(yes, I’ve found typos in other versions formulated by smaller committees) and the attention to detail they have displayed in bringing to life the timeless stories and moral teachings of the Bible for a modern readership. The NLT is available in the 66 books that comprise the Protestant Bible, but they have also produced a Catholic version (with its 72 books). The comments made here refer to the former.

The first edition of the NLT was published in 1996 and its aim was to turn the paraphrased Living Bible (composed by the late Kenneth Taylor in 1971) into a proper translation. It has since undergone several revisions (2004, 2007, 2013 and 2016), which aims to make the text as accessible and inclusive as possible. Like the NIV, the language is quite gender neutral, but the committee has clearly not gone as far as their NIV counterparts, which some feel has taken the issue a wee bit too far. Weights, measures and the timing of religious festivals are expressed in modern terms, which adds to the intelligibility of the text. The introduction pages to this Bible clearly explains why these strategies were adopted.

While it is acknowledged that any thought-for-thought translation is in danger of going too far, and that, ultimately, you are probably safer going with a good literal translation like the ESV, NKJV or NASB, I find there is much that is meritorious about this fresh, dynamic and often idiomatic edition of the Bible. I found it is excellent for speed reading( I obtained my copy in October 2018, but had sampled an earlier edition before giving it away to a friend), having completely finished it in just a few months. Although some renderings of the text were mildly alarming(see Luke 5:30 for an example), on the whole I thought the translation was very enjoyable and worth the effort to read through. At no point did I ever feel that the translators were watering down Scripture (e.g. the deity of Christ or the nature of the triune God), as some commentators have suggested. Indeed, in some cases, I felt it was easier to understand certain passages about the Atonement than in more literal word-for-word translations.

Many of the Psalms will come across as unfamiliar to those who cherish traditional translations, like my beloved NKJV, because the wording is different, but I found the differences enriching more than they were distracting. Consider Psalm 23, for example:

The Lord is my shepherd;
    I have all that I need.
He lets me rest in green meadows;
    he leads me beside peaceful streams.
He renews my strength.
He guides me along right paths,
    bringing honor to his name.
Even when I walk
    through the darkest valley,
I will not be afraid,
    for you are close beside me.
Your rod and your staff
    protect and comfort me.
You prepare a feast for me
    in the presence of my enemies.
You honor me by anointing my head with oil.
    My cup overflows with blessings.
Surely your goodness and unfailing love will pursue me
    all the days of my life,
and I will live in the house of the Lord
    forever.

Psalm 23

As you can see, it is worded rather differently to more celebrated versions of the Bible such as the grand old King James Version (which my family and I have committed to memory) but if I’m being honest, it conveys exactly the same comforting ideas as older renditions of this time-honoured Davidic psalm.

I would highly recommend this translation to everyone, but especially those who are making their first steps in the faith. I completely reject the idea that it is an inferior version compared with the more technically accurate renditions of the Bible, for I equate this kind of thinking to yet another example of legalism, which is just plain wrong and anathema to the true message of the Gospel. Afterall, God never intended for His inspired word to be misunderstood or that it be made accessible to only an elite few. Have we not learned anything from the days when the Latin Vulgate was the only version in existence, delivered and understood only by priests?

As our Lord and Saviour once declared:

O Father, Lord of heaven and earth, thank you for hiding these things from those who think themselves wise and clever, and for revealing them to the childlike.

Matthew 11:25(NLT)

That we have so many versions is a blessing and not a curse. Personally, I see it as part of the Divine plan to bring as many people to Christ before the Lord wraps it all up. I for one cherish the NLT as a fine addition to my Bible collection and one which I will continue to use and enjoy until the day I see Him face to face.

Ultimately, the message of the Bible is joyful and optimistic to those who have the wisdom to accept its teachings. So believers have absolutely nothing to fear! Indeed, Scripture anticipated that these radical changes in human society would occur near the closing of the age. It’s as if prophecy is unravelling before our very eyes, and that gives me goose bumps! In the meantime, we just have to keep on trying to make the world a better place and to speak up for issues that we believe are immoral. Moreover, the Bible has always encouraged us to be vigilant in the times we are given to live in. So take heart! Nothing should surprise you!

A few Words on the NLT Premium SlimLine Large Print Reference Edition ( ISBN- 978-1-4143-0711-4)

Now, I would like to say a few words about the particular NLT Bible I have sourced.

As I explained in a previous blog about my NKJV Bible, I like to have a hard copy of any Bible I purchase. The NLT is, of course, available for study online, but like any other Bible I use, I prefer to have a copy I can bring anywhere with me, without the hassle of relying on using electronic devices to retrieve the text. Afterall, we cannot be certain that we will have the internet forever, can we?

This NLT measures 6.5″ x 9″ and is about an inch thick. It has a paste-down liner and a strong, Smyth-sewn binding. The cover is Leatherex; making it very flexible and durable. It is very attractive to the touch and is easy to grip. It is not ostentatious and will not make you stand out in a crowd. It lies flat when hand-held or when opened on a table. The words are printed in 9.84 font, so very easy to read, even without my glasses. The quality of the paper is not the best but not the worst either, and is perfectly adequate for reading.  It has two colour-matched ribbons page markers to keep track of whatever text from the Old and New Testament I’m studying from.

The edges of the pages have a very nice gold gilding. The text is fairly well line matched with only a little bit of bleed-through visible from page to page. This is a red letter version. The colour of red is slightly paler than I would have liked but it does the job fine.I don’t really like footnotes, so I was delighted to see that they are minimal in this version of the NLT and are placed at the bottom of the page, where they provide little in the way of a distraction and are also printed in a smaller font size to the main text.

At the back of the Bible, there is a fairly comprehensive 53-page concordance, followed by a single page presenting ” Great Chapters from the Bible.” This is immediately followed by a 3-page presentation of what the committee consider to be the “greatest verses from the Bible.” The last few pages present a useful 365-day reading plan to get the user through the entire Biblical text in a single year. Finally, like most Bibles, it presents a few useful full-colour maps of the Holy Land, including a detailed look at the places Jesus visited during his three and a half year earthly mission, as well as maps of the Greek, Babylonian and Assyrian Empires,and which also includes the route of the Exodus and the missionary journeys of Saint Paul.

For a modest cost of £26.99. I consider it a good value in today’s market.

 

I hope readers will receive the NLT with enthusiasm and that it will enrich your knowledge of the Bible in these somewhat alarming but ultimately exciting(for Christians and Messianic Jews)  times in which we now live!

With Every Blessing,

 

Neil.

Earth & Sky.

“Moonrise” by Stanislaw Maslowski (1884); image crdit Wiki Commons.

In a fallen world, where mankind’s rebellion against his Creator is now rapidly reaching pre-flood levels of wickedness, it’s good to know that the planet Earth is still a pretty neat place to live. Protected by a just-right atmosphere of mainly nitrogen and oxygen, the Lord of Heaven’s armies has packed this planet full of living things and amazing geological features that bring joy to the human heart.

Our atmosphere is neither too dense or too rarefied, allowing us to peer deeply into the Cosmos, where we have caught a glimpse of eternity.  And all around us, our Creator has left clear evidence of His handiwork so that we are without excuse on the day of judgement.

The human eye can only see so much though, but our Creator chose to give us a mind that enables us to improve our lot, to see things in new and different ways. That’s how I see my binoculars; simple tools that bring heaven and Earth closer, providing a perspective that transcends the limitations of my corporeal form. I am especially fortunate to live in a beautiful part of the world, away from the cities where atheism flourishes. Out in the sticks, I can enjoy the beauty of God’s creation more fully, in quietness, surrounded as I am by hills and valleys, green fields and lovely streams of cool, fresh rainwater that sustain the lives of all living things.

My wide-angle 8 x 42 binocular, in particular, is the perfect tool for combining the beauty of the night sky with that of the comeliness of the earthly creation. And in this blog, I would like to share with you some of the kinds of activities I get up to to bring these worlds together. This binocular provides a power of just 8 diameters but has an angular field of view wide enough to fit over 16 full Moons in the same wonderful portal. And with its decent light grasp, especially in fading or low light, it is powerful enough to allow me to simultaneously appreciate sights in the heavens and on earth.

                                                  Picture Postcards

Surrounded by mature trees, sometimes many times older than myself, I have grown terribly fond of framing famliar celestial sights, such as the Pleiades and the Hyades in the foreground of their impressive branches. Sometimes, I would wait for the stars in these clusters to fall in altitude after they culminate in the south, so that they are seen to ‘hover’ over the conifer trees beyond my back garden. And if, by chance, the presence of a gentle breeze in the binocular image is witnessed (and it can happen a lot!), then you’ve got a home run; an epiphany of sorts! At other times, I will plan a vigil where the soft light from the stars fills the background whilst the foreground is occupied with denuded winter branches of the deciduous trees near my home. A little light pollution can actually be advantageous in such circumstances as it can help illuminate the tree branches making them stand out more boldly against the stellar backdrop.

Living inside a long valley with verdant hills that soar to about 1000 feet on either side, my binocular is good at framing the rising Moon as its silvery light clears their summit in the east, or as it sinks behind the hills in the west. There are many times where I can plan to observe the Moon and the hilltops in the same field, creating visual scenes that leave a deep impression on me. I give thanks to my God for allowing me to witness such scenes, safe and secure at the bottom of a great sea of fresh, clean air.

Ever since childhood, I have been attracted to storms, often venturing out to feel the energy they generate in the atmosphere. Sometimes these storms occur on moonlit nights and I would think it nothing to grab my binocular and carry myself off to some favourite haunts, woody glades and the like, where moonbeams create wonderful atmospheric scenes, complemented by the sound of wind whistling through their branches.

My binocular has renewed my interest in observing the full Moon, not in and of itself, but when it is surrounded by low lying and fast-moving rain clouds, as often happens here in the British Isles. I watch as these clouds enter the outer field, inching their way toward the bright satellite, and all the while lighting up with beautiful colours caused by refraction of moonlight through raindrops. The colours often start off deep and moody, like dried-in blood, when far from the Moon, but as they move ever closer, the colours they generate; gorgeous shades of pink, yellows and even rose tints; saturate the cones on my retina and,  upwelling feelings of great happiness.

The structure of clouds backlit by moonlight reveals wonderful, highly complex structures, as well as colours – knots, filaments and pleated sheets. Often the scene reminds me of the play of light on the matter which is expelled into the shells of planetary nebulae as imaged by a great telescope, with a white dwarf star being replaced by our very own Moon at its epicentre lol. Such natural shows of light and form rank as some of the most lovely and most surreal binocular images one is likely to capture. Sometimes, great gaping holes in the heavens open up around the clouds, allowing the light of the distant stars to be seen near the full Moon.

Dawn and dusk are good times to see some spectacular sights, such as the bright planet Venus sinking low into the sky, often silhouetted by interesting terrestrial structures, such as a distant hill,  an old barnhouse or silo, church or windmill. By getting to know your horizons, sublime scenes can be captured with your binocular, bringing heaven and Earth together, just like it will be in the New Creation.

Cityscapes can also be used to enhance the binocular view. Framing bright star clusters like the Pleiades or a crescent Moon in the background to an old church spire, domed cathedral, or grand municipal building, can make for a very fetching sight. Photographers  imagine likewise,of course, but the impromptu binocular experience is an even greater liberal art!

Another worthwhile project is to image the bright Moon over a large expanse of water, especially during calm conditions, when its  reflection  is quite mirror-like. Under the light of a town or city, smaller binoculars do just fine, like my little Pentax DCF 9 x 28 pocket instrument. You can even wander through your neighbourhood finding interesting foreground subjects to frame your celestial scenes in advance of an event.

It’s good to plan.

Well, I hope you get some ideas from this short article. In doing so, you can enjoy the best of the heavenly and terrestrial creations, and which can turn an otherwise mundane evening or morning into a very memorable one!

Happy hunting!

Origins of Life: A Closer Look Part II

Imitation is the sincerest form of flattery!

 

 

Continuing a critical analysis of Professor Jack Szostak’s Origin of Life scenario proposed here.

See Part I for comments on earlier sections of the video

The goal: to critically appraise each of the steps Dr. Szostak presents in light of the latest research findings that show that any such scheme of events is physio-chemically untenable from a purely naturalistic perspective.

Video Clock Time 10-30 mins

Dr.Szostak’s RNA chains contain homochiral ribose (D ribose) though he has not disclosed how this D ribose originated. This is a crucially important point that the reader must gain an appreciation of. This will be discussed on this page.

No D ribose, no nucleotides, and no oligonucleotide chains.

Dr. Szostak completely avoids another intractable problem for his chemical synthesis scenario; that of the homochirality of sugars and amino acids. As shall be outlined in the next section, this is a very exciting and fast moving arena of research (owing to the pressing nature of the underlying problem), but as I shall demonstrate, it is still a mystery.

One of the key molecular features of life is that its major polymers are built up from chiral molecules. Chiral molecules exhibit handedness. All celllular life on Earth utilises left handed amino acids (L amino acids) and right handed sugars (D sugars). The L and D forms of the same molecules are called enantiomers and can be distinguished by how they rotate the plane of plane-polarised light in aqueous solution (either to the left or right) Because amino acids and sugars in all life on Earth exclusively incorporate L and D enantiomers, respectively, they are said to be homochiral.

The problem begins when scientists set out to explore synthetic means of producing molecules such as ribose, which almost invariably produce a 50:50 mixture of both enantiomers. Such a condition is said to be racemic.

To maintain biochemical viability, the ribose must be 100 percent in the D enantiomeric form; mixtures will soon grind any synthetic scheme to a halt.

Looking for solutions: what the latest research (as of 2015) has revealed

Scientists have been searching for many decades for a solution to the homochirality problem. One source was shown to occur via the production of 100 per cent circularly polarised light derived from the vicinity of black holes and neutron stars. This light selectively destroys one enantiomer over the other, with the result that one chiral form is selected for. The problem with this astrophysical source is that it only generates 20% enantiomeric enrichment, not enough to allow life processes to proceed or to explain the homochirlality problem.

Reference: Hazen, R.M., Life’s Rocky Start, Scientific American (April 2001)  77-85.

Molecules are not the only entities that exhibit mirror images of each other. In physics, the parity principle states that physical processes that display symmetry about a central plane operate as mirror images. According to this principle, nature shows no preference for either left- or right-handedness. In the 1950s however, physicists discovered an exception to this rule, referring to this interesting idea as a parity breaking. Chinese physicists demonstrated that the electro-weak force displays a slight preference for left-handed  amino acid enantiomers . When a radioactive nucleus undergoes decay via the weak nuclear force, it emits polarised light with a slight left-handed bias. Some physicists have suggested that this parity breaking could have led to homochirality. But since the energy difference between enantiomers is only of the order of 10 J Mol^-1 it would have no appreciable effect on chemical reactions, a situation endorsed by leading astrobiologists.

Reference: Rikken, G. L. J. A. Rikken & Raupach, E., Enantioselective Magnetochiral Photochemistry, Nature, 405 ( 2000), 932-35.

The inconvenient truth about homochirality in biochemical systems has led some more zealous scientists to uncover chemical means to surmount the problem. The most promising of these will be discussed here.

One way to create some chiral excess is a process called oligomerisation. Biological polymers are built up of subunits called monomers. By chemically linking up these monomers a polymer is created. An oligomer is an intermediate state between a monomer and a polymer, usually having several tens of monomer units. Some laboratory studies have shown that oligomerisation reactions are inhibited  when a racemic mixture of monomers is incorporated into the reaction. Specifically, if the researchers add the opposite enantiomer of a nucleotide during the oligomerisation of RNA nucleotides, the addition inhibits the reaction. This, some researchers have suggested, provides a way of producing homochiral polymers.

Reference: Joyce et al, RNA Evolution, pp 217-24.

The main problem with this model resides with the probability of assembling sufficiently long RNA oligomers for it to allow the process to occur in a realistic prebiotic setting. To get anything viable, at least 50 subunits must be routinely produced and preferably much longer chains. As a result, most researchers in the field now consider the probability of this mechanism favouring homochirality to be too remote to be a viable option. Others have suggested that enantiomers with the same handedness could react preferentially to form the oligomer chain. However, no such selectivity  has thus far been observed in laboratory experiments.

Theoretical work first conducted in the 1950s by the chemist F.C. Frank showed another way forward; Asymmetric Autocatalysis.

A chemical reaction in which one or more products serve as a catalyst is called autocatalysis. In this process, the enantiometric products selectively exert  their catalytic activity driving the production of one or more compounds of the same molecular handedness. In exact racemic mixtures, asymmetric autocatalysis would lead to no chiral excess. In reality however, chemical reactions are never an exact 50:50 mixture. Statistical fluctuations cause nearly imperceptible imbalances of enantiomers. This slight excess, created by statistical fluctuations- can be amplified. One demonstration of this mechanism is called the Soai Process, after the Japanese chemist, Kenso Soai, how first  elucidated it in the 1990s.

Reference: Blackmond, D.G,  Asymmetric Autocatalysis and its Implications for the Origins of Homochirality, Proceedings of the National Academy of Sciences (PNAS),101, (April 2004) 5732-36.

The Soai process involves the alkylation of pyrimidyl aldehydes by dialylzincs. The product of this reaction is a pyrimidyl alcohol that can exist in left- or right-handed enantiomers. Soai discovered that the alcohol products catalyses this transformation. As the pyrimidyl alcohol products are produced, statistical fluctuations cause these compounds to display a slight excess of one of the enantiomers over the other. This minor imbalance sets up asymmetric autocatalysis i.e. the more abundant enantiomer selectively catalyses the production of its corresponding chiral counterpart Over time, chiral excesses on the order of nearly 99 per cent can be achieved.

Soai’s discovery may sound like a plausible breakthrough to creating homochirality but significant problems remain. For one thing, the Soai reaction has no relevance in biological systems as none of the reactants and products have been documented in bona fide biological systems. In addition to this, this reaction is the only real-life example of asymmetric autocatalysis discovered to date.

Further theoretical studies of asymmetric autocatalysis reveal that the chiral excess produced by this reaction is short-lived; because it rapidly decays from near 99 per cent chiral enrichment back to the racemic condition (50 per cent) caused by the activity of the other enantiomer, which also acts as an autocatalyst, competing with its mirror image. Curiously, this does not occur in the Soai reaction because the enantiomer that achieves an excess not only acts catalytically but also acts as its own anticatalyst. The oddity of the Soai process is more a reflection of the scientist’s genius in recognising the underlying mechanism  and pursuing it experimentally and not a general chemical principle.

Other chemists and astrobiologists have looked for other autocatalytic mechanisms that are relevant to studies of prebiotic chemistry. In particular, chemist Sandra Pizzarello and Arthur Weber have shown that the amino acids alanine and isovaline (which shows slight chiral enrichment in the Murchison meteorite) can catalyse the formose reaction leading to ribose.

Specifically, when amino acids that catalyse the formose reaction harbour a chiral  exess, the sugar products generated also display a chiral excess. In other words, the amino acids are able to transfer this chiral excess  to the sugar products. Researchers observed that when the amino acid catalysts were enantiomerically pure, the sugar products displayed a chiral enrichment of up to 10 per cent. Yet, as the enantiomeric purity of the amino acid declined, the chiral excess of the sugar products also decreased. Of particular note is that when the enantiomeric imbalance of the amino acid catalyst reached 10 per cent, the chiral excess in the sugar products became imperceptible.

Further research by the same scientists showed chiral enrichment when homochiral dipeptides were used as catalysts.

Reference: Pizzarello, S., Weber, A.L., Prebiotic Amino Acids as Asymmetric Catalysts, Science 303 ( February 20, 2004), 1151.

A dipeptide consists of two amino acids that have undergone a condensation reaction, linked by a peptide bond. Curiously, the dipeptide catalysts yielded an 80 per cent chiral enrichment, raising hopes that this could have been the breakthrough origin of life researchers were looking for. But, yet again, there are problems with this scheme of events. As shown in Part I, it is not at all clear where such homochiral dipeptides might have originated from. Carbonaceous chondrites have been suggested as a possible source. In addition, relatively high concentrations of these dipeptide catalysts were required in laboratory experiments to generate this chiral enrichment, so much so that stretches credulity that the concentrations required were ever attained on the primordial Earth. But there are more sonorous reasons why either asymmetric or symmetric autocatalysis could ever have been a viable option; which derives from the properties of chiral molecules themselves.

Firstly, the dipeptide catalyst require extremely exacting pH and temperature regulation if they are to act out their roles. In other words, this phenomenon only works within very narrow temperature and pH regimes, something very unlikely to occur on the primordial Earth. A chemical process that does not have geological relevance creates a further problem for chemical evolutionary models for the origin of homochirality. Worst still, the examples explored above which generate homochiral excess are transitory at best. The reasons are due to the fact that enantiomers establish a dynamic equilibrium with each other that cause them to flip flop between enantiomeric states; a process called racemisation. This process causes enantiomerically pure compounds to transform over time back to their racemic form through structural inversion. Laboratory studies estimate that a set of homochiral amino acids would become completely racemic in one thousand years at 50 C and in one million years at 0 C under dry conditions, but much faster under aqueous conditions.

Curiously, a paper published in Nature Communications in December 2018, raised considerable concern about the practices of prebiotic chemical research. In particular, the author (Richert), expressed concern over the number of human interventions needed for such research to be conducted and that “the hand of God” phenomenon, as the author himself put it, was not being addressed.

The consequences of racemisation are troubling for chemical evolutionary scenarios, because even if homochiral excess could be achieved, it could not be realistically maintained  on the primitive Earth. The important point to remember here is that all such studies ignore, or fail to account for, the transitory nature of achieving chiral excess. This means that because the researchers have to stop and start their experiments as soon as they achieve some enrichment, they unconsciously cultivate a false sense of success. This is intelligent design through and through!

                                              A Closer Look at Hydrothermal Vents

Dr Szostak has emphasised prebiotic molecule synthesis at hydro-themal vents. The origin of these ideas come from a team of Japanese researchers who had searched for ways that homochirality could be produced at such sites. In their simulation studies, designed to mimic hydrothermal vents, these investigators noticed that both left-handed and right-handed versions of the amino acid alanine undergo racemisation from a pure state at 230 C in a matter of 30 to 40 minutes. To their surprise however, the left handed enantiomer is racemised to a slightly lesser extent than the right-handed counterpart. This effect was concentration dependent however, occurring when there was only unrealistically high concentrations of alanine present.

                                                       PNAs and that…...

These studies prompted the late Stanley Miller to formerly acknowledge the intractability of the problem of homochirality’s origin. As a consequence, he proposed that the first replicating molecules were achiral peptide nucleic acids (PNA).

Reference:

Nelson, K.E., et al, Peptide Nucleic Acids Rather Than RNA May Have Been the First Genetic Material,  PNAS, 97 (April 11, 2000): 3368-71.

Miller was drawn to these models because he knew no meaningful progress could be made using sugar- or dipeptide-based catalysts, as discussed above. PNA chemistry is simpler, because neither does it contain sugar or phosphates and because they can form base pairs as well as helical structures. The nucleobases of PNA are joined together through a molecule of acetic acid and a chiral amino acid of non biological origin; 2-aminoethyl glycine (AEG). For a PNA origin-of-life scenario to be viable, a plentiful source of acetic acid, nucleobases and AEG had to identified. To date, only acetic acid synthesis has been achieved and AEG has not been detected either terrestrially or extra-terrestrially.

Miller’s PNA molecules  have other problems however; they are stable; too stable. They bond very strongly to any daughter molecules they may have replicated but could only do so very slowly, too slowly to be relevant to realistic origin-of-life scenarios.

                                                             Mineral Surfaces

Another possibility for the origin of homochirality is via mineral surfaces, discussed by Dr. Szostak in his video. Some mineral surfaces can indeed generate chiral excess, which has given rise to some optimism in the prebiotic chemistry community.

Reference:

Hazen, R., et al, Selective Absorption of L-and D-Amino Acids On Calcite: Implications For Biochemical Homochirality, PNAS 98 (May 1, 2001) 5487-90.

This proposal involves clays and mineral surfaces with highly specific chemical and spatial orientations – like quartz and calcite – that can selectively absorb either left- or right-handed enantiomeric substrates. Curiously, it was discovered that when these surfaces were exposed to dilute solutions of amino acids, they will differentially become absorbed onto these surfaces creating a chiral excess.

Reference: Ibid

But let’s take a closer look at this process. For one thing the mineral surfaces must be ultra clean. The actual laboratory protocol for creating these surfaces involves successive washings in this order; deionised water, ultra-pure methanol, methylene chloride, more ultra-pure methanol and finally another soaking in deionised water. No contamination can be tolerated to even get the process started.

This in and of itself raises serious doubts as to the validity of using clay surfaces as loci for the naturalistic generation of chiral excess, as no real life site could be expected to offer such ultra clean surfaces. What is more, such crystal structures actually occur in two forms – opposite in their chiral specificity. This would produce only very small and geographically dispersed opportunities for any absorption to take place, preventing the build up of high enough concentrations of prebiotically relevant reservoirs of such molecules.

                                    Crystallisaton-induced Homochirality Studies

One more mechanism of achieving chiral excess has been recently explored; crystallisation. The great French chemist and microbiologist, Louis Pasteur was one of the earliest investigators of homochirality, when he was able to distinguish between L tartaric acid and D tartaric acid using a microscope. This chiral preference occurs with other substances too and leads to the formation of enantiomerically pure crystalline forms. This curious phenomenon has encouraged researchers to investigate whether this differential ‘sifting’ of prebiotic molecules on the primitive Earth could have led to homochirality.

When evaporated to dryness in the presence of a porous material, the amino acids, aspartate and glutamate will form crystals that are enantiomerically pure. But this is the exception rather than the rule because, under, normal circumstances the crystals usually form racemic arrays. However, in the presence of some porous materials, they can form supersaturated solutions during evaporation, and, as a result, produce enantiomerically pure crystals.

Researchers led by Ronald Breslow (whose names also makes an appearance in Szostak’s presentation) of Columbia University suggested that it was in fact the material that was left behind in the solution during the crystallisation  event that was the source of the homochirality and went on to show this was indeed the case for the amino acid phenylalanine. While the crystal contained a racemic mixture of the amino acid, the aqueous phase became enriched with the enantiomer that initially showed a slight statistical excess. Furthermore, Breslow et al showed that a chiral excess of about 1 per cent can be amplified to about 90 per cent after just two successive rounds of crystallisation. They envision a scenario on the early Earth, where carbonaceous chondrites might have seeded the oceans with amino acids. Tides would then wash these amino acids onto ancient beaches and, after evaporation, crystals would form and a slight chiral excess of the other enantiomer. This, they claim, would have slowly caused the build up of one enantiomer over the other, leading the way to homochirality.

But this reasoning is flawed. Dr. Fazale Rana, in his recent book on the matter, Creating Life in the Lab, presented the reason why; amino acids tend to stay single in aqueous solutions and not form higher order structures like peptides. This is thermodynamically the most stable state for them in this environment. The Columbia University researchers have tried to counter this argument by suggesting that condensation reactions would begin during the drying out phase in this scheme of events.. But as Dr. Rana has pointed out, these amino acids would be a racemic mixture with little or no chiral excess. Thus, the mechanism proposed as the origin of homochirality would in fact inhibit the process! In addition to this, any dipeptide exposed to the fierce UV flux from the Sun (remember there was no ozone layer) would quickly degrade them. One need only look at how biotechnology companies recommend they be stored to verify this (personal communication). See here and here for examples.

Summary:This section discussed at length the concept of homochirality, the handedness of life’s sugars and amino acids. Szostak’s RNA chains were all produced with pre-primed nucleotides, replete with ready made D-ribose. The work illustrated shows that producing D ribose under credible prebiotic conditions (and indeed the L amino acids) has not been satisfactorily achieved and that any process that attains significant chiral excess is actually the result of careful  adjustment of the experimental conditions and artificial selection of specified outcomes; again the manifestation of intelligent design. As we have seen, the inherent tendency for an enantiomeric excess to rapidly return to its thermodynamically most stable state, that is, racemic, would severely curtail or completely halt any realistic abiogenic scheme. The probability of achieving true homochirality via naturalistic mechanisms is very highly unlikely, if indeed well nigh impossible.

I leave you with a quote from Francis Crick and Leslie Orgel’s book: Life Itself

An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.

On Vesicles:

One of the basic properties of living cells is their ability to maintain a chemical environment distinct from the space surrounding it. Life exists in the world and despite of the world, but is not of the world. This is achieved by creating a membrane which separates internal chemistry from external chemistry. Researchers have known for many years that under laboratory conditions certain kinds of molecules – what Dr. Szostak calls amphiphiles – made from fatty acids and phospholipids, which can form spherical structures called vesicles. An amphiphile is a molecule which has has both hydrophobic and hydrophilic natures. We are all familiar with the old adage; oil and water don’t mix. That’s because oil does not have chemical groups that can stably interact with water, blending with it, to create a solution. They are said to be hydrophobic because their chemistry does not permit them to dissolve in water. Molecules that have the right chemical groups to stably interact with water are said to be hydrophilic. Sugars are good examples of hydrophilic molecules. An amphiphile, as its name implies, has both hydrophilic and hydrophobic properties, allowing them to form unstable suspensions in water, usually in the form of single-layered micelles. Phospholipids – the components of real cells – and fatty acids (discussed by Szostak) possess such amphiphilic properties. When shaken up in an aqueous environment, they arrange themselves in such a way that their hydrophobic ends huddle together, like oil, and their hydrophilic end points outwards to form stronger interactions with water. The most stable (read lowest energy) arrangements are spherical structures – the vesicles that Szostak describes in his video.

Superficially, these vesicles look like cells and have served as a starting point to create the protocells he describes. As Dr Szostak explains, these membrane-bound vesicles can segregate materials located inside them from their surrounding environment.

As well as providing a physical barrier from the outside world, membranes harbour proteins that act as channels and transporters of molecules both into and out of the cell . They also act as sensors of the environment, as well as energy transducers. Synthetic biologists such as Dr. Szostak have to figure out not only how to form vesicles but also enable them with a means of transporting substances across their boundaries. One way forward is to try to manipulate the chemical structure of these amphiphiles in such a way that they can incorporate proteins both inside and on the membrane in order to serve as pores, environmental sensors and energy transducers.

As most any high school student of biology will tell you, reproduction is one of the basic characteristics of all living cells and this ability fundamentally resides in its DNA, which is replicated and then partitioned into two daughter nuclei before the cell fissures. Scientists must thus find ways to encapsulate DNA (or in this case RNA) molecules within the vesicle. When supplied with the right mix of chemicals, the encapsulated genetic material can then be used to synthesise proteins, which in turn could at least set the stage for the replication of the ‘protocell.’ The trick is to find a way to get the vesicle to divide in two, and in such a way that ensures that each new daughter vesicle has a copy of the genetic material.

So the process can best be seen as a series of steps which include;
1. The membrane has to be assembled.
2. Development of an energy transducing capability by the boundary membrane.
3. Genetic material must be encapsulated into the vesicle.
4. Pore proteins must be added that can funnel material into and out of the vesicle.
5. Generation of membrane bound systems that allow complex molecules to grow.
6. Generation of catalysts to speed up any given chemical process within the vesicle e.g. DNA/ RNA replication.
7. Introduction of information-rich molecules that can direct the synthesis of other molecules of benefit to the developing chemical environment within the vesicle
8. Development of mechanisms that cause the boundary membrane to subdivide into smaller systems that can demonstrate ‘growth’.
9. Development of a means to pass information containing molecules into the daughter vesicles.

As you imagine, this is an incredibly complex process, effortlessly achieved by even the simplest living cells, but the list serves to illustrate one approach to the creation of artificial life; the so-called ‘ground up’ approach. This is the approach adopted by Szostak and his team.

Starting in the 1990s, he and his colleagues have exerted great effort into getting vesicles to grow and divide, getting genetic material to replicate and evolve within these vesicles and the creation of artificial proteins by either synthesising them under laboratory conditions or utilising pre-existing proteins that have been genetically engineered. Szostak coordinates several teams of scientists who bring as many of these steps together to create states that indeed show some of the characteristics that we would recognise as ‘alive’.

Like all scientists, Szostak builds his work on the shoulder of others who have pioneered methods to produce vesicles from purified phospholipids, trap molecules of interest within them and then incorporate purified proteins into the vesicle walls. Synthetic biologists like Szostak strive to capitalise on the vesicle forming properties of amphiphiles in order to construct protocells. The first such experiments began with the pioneering work of membrane biophysicist Pier Luigi Luisi, who encapsulated ribosomes (the molecular machines which carry out protein synthesis and other chemical components within phospholipid vesicles and, in so doing, managed to create an artificial protein – polyphenylalanine – within the vesicle.

Reference:

Oberholzer, T., Nierhuas, K.H. & Luisi, P.L., Protein Expression in Liposomes, BBRC, 261, (August 1999) 238-41

This work was followed up by other researchers who investigated ways of designing protocells consisting of vesicles made from simpler amphiphiles such as fatty acids, because they were considered more versatile than phospholipids (which are actually found in real cell membranes). Luisi and his collaborator Dr. David Deamer (cited on Szostak’s slides). By the early 2000s, Deamer‘s group showed that fatty acids can indeed assemble into bilayers ( just like real cell membranes) but under highly specific conditions, of concentration, pH, temperature and salt concentration. Furthermore, all of these conditions vary considerably between fatty acid species.

Reference:

Hanczyc, M.M., Fujikawa, S.M.,Szostak, J., Experimental Models of Primitive Cellular Compartments, Science 302 (October 2003): 618-22.

Luisi’s team showed that certain kinds of these vesicles can ‘grow’ if supplied with more fatty acids. This causes the vesicles to enlarge, become unstable, before dividing into two daughter vesicles. The same researchers have used fatty acid vesicles to encapsulate interesting enzymes such as polynucleotide phosphorylase, which uses adenosine diphosphate (ADP) as a substrate to build the DNA analog called polyadenylic acid.

Reference:

Thomas, J.A & Rana. F, The Influence of Environmental Conditions , Lipid Composition, and Phase Behavior on the Origin of Cell Membranes, Origins of Life and Evolution of Biospheres, 37( June 2007): 267-85

This was widely cited in the origin-of-life community as a sort of ‘proof of concept’ that genetic material could indeed replicate inside vesicles and hence a demonstration of the first step towards the generation of self-replicating protocells.

Szostak’s group built on all these successes to attempt to create more life-like protocells. Specifically, they allowed fatty acids to interact with mineral surfaces (discussed above) and showed that this improves the efficiency of vesicle formation.

But vesicles constructed from fatty acid substrates have marginal long-term stability. Another show stopper is that even small amounts of salts (ionic substances) completely inhibit vesicle formation, a point completely avoided by Dr. Szostak. What’s more, the consensus opinion is that primordial oceans would have had a higher salinity than those existing today. What is more, real cell membranes are not symmetrically arranged but are asymmetric, providing much greater complexity than anything utilised by Szostak’s team. See here for a commentary on membrane biochemistry. Yet again, without the maintenance of exacting conditions of pH, temperature, salinity, etc, these vesicles would fall apart. Indeed, no method has been demonstrated that can maintain stable, long-lasting vesicles. Such stability is a necessary pre-condition to the creation of artificial life.

Szostak’s team has explored ways to get vesicles to grow and divide like real cells. By the addition of fresh fatty acids to the medium and studying their behaviour, his team has developed a deeper understanding of how this process works.
Reference:

Chen, I.A., Szostak, J., A Kinetic Study of the Growth of Fatty Acid Vesicles, Biophysical Journal 87, (August 1 2004) 988-98.

While Luisi’s team produced vesicle fissuring, they do so unstably. Szostak’s team have addressed this issue by developing ways to sustain vesicle division after a period of growth. This is achieved by pushing the expanded vesicles through pores (extrusion). In so doing, Dr. Szostak has shown that the process can be repeated indefinitely to create multiple ‘generations’ of protocells.

Reference: Hanczyc, M.M.& Szostak, J., Replicating Vesicles as Models of Primitive cell Growth and Division, Current Opinion in Chemical Biology 8 (December 2004) 600-64

When Szostak et al encapsulated RNA molecules inside such vesicles, they actually promote growth because they produce osmotic pressure on the vesicle walls, increasing membrane stress, which in turn allows fresh fatty acids to become incorporated into the bilayer membrane. He further showed that the RNA molecules are retained inside the vesicle after filter extrusion. Researchers have also encapsulated clay minerals inside vesicles, along with RNA, and demonstrated that the clay is also retained by the vesicles during the growth and division process.

The next phase in this ‘bottom up’ approach is to provide an energy source for more sophisticated protocell activities. Cells use pH gradients as a way to harvest energy. Indeed this is the fundamental way in which all real cells synthesise the universal energy currency of life: adenosine triphosphate (ATP).

To this end, some researchers have incorporated special molecules which can absorb light into phospholipid membranes to create such pH gradients. Then by adding the pre-existing enzyme complex F0F1 ATP synthase (a remarkable molecular machine in its own right!), they were able to use these pH gradients to synthesise ATP.

Reference:Steinberg,-Yfrach, G. et al, Light-Driven Production of ATP  Catalysed by F0F1 ATP Synthase in Artificial Photosynthetic Membrane, Nature 392 ( April 2, 1998) 479-82.

Szostak’s team has simplified this process. Specifically, they found that the growth of vesicles made from fatty acids naturally generates pH gradients. So, the growth and division of vesicles can provide an energy source.

Reference:Chen, I.A, Szostak, J, Membrane Growth can Generate a Trans-membrane pH Gradient in Fatty Acid Vesicles, PNAS 101( May 25, 2004) 7965-70.

The fatty acid vesicles created by Szostak’s team delivered another advantage over their phospholipid based counterparts; they were more permeable, allowing easier transport of molecules both into and out of the vesicle. Activated (pre-made) nucleotides, which serve as the building blocks for DNA and RNA, were able to move into the vesicles more easily. This led the team to develop systems that could incorporate these activated nucleotides and, using a pre-encapsulated strand of DNA, demonstrated replication capabilities. In addition, his laboratories began experimenting with different types of amphiphiles (including unsaturated fatty acids, alcohols and monoglycerides), mixing them up to try to optimise their stability between the freezing and boiling point of water.

Reference: Mansy, S. & Szostak, J. Thermostability of Model Protocell Membranes,  PNAS 105 (September 9, 2008) 13351-55.

These are important advances, because they have steadily improved the robustness of their protocells and allow scientists to chemically replicate genetic material within the interior of the vesicle. Szostak’s group at Harvard hope to learn how to coordinate the replication of the genetic material encapsulated within these vesicles with the process of vesicle fission. By engineering more and more properties into these vesicles, Szostak and his collaborators hope to create systems tailor made to carry out specific functions. Their ultimate goal is to create synthetic cells that can carry out novel biochemical processes in order to make new biomedical advances and novel pharmaceuticals that will greatly enrich biotechnology. Some foresee that, at the current rate of advancement, these will be a reality as early as a decade from now.

Summary

What Professor Szostak and his colleagues have achieved is truly remarkable! By divesting many millions of dollars from public and private donors, recruiting a very large team of the finest biochemists and molecular biologists, and  utilising the most advanced equipment ever assembled, real progress can be made and his success is bound to continue over the coming years. But, as I have indicated previously, this progress has not come about through Darwinian means, far from it! What Szostak’s work has demonstrated is that by deliberate effort and the harnessing of extraordinary human ingenuity, the era of synthetic biology is well and truly upon us. Their work empirically shows that even the simplest life-form ( which are orders of magnitude more complex than the ‘protocells’ discussed) cannot arise without the involvement of an intelligent agent.

Fatty acids do not  form bi-layered membranes when added to ordinary water. On the contrary, their work shows that it is possible to coax stable vesicles to form only by making conscious choices about the kinds of fatty acids (in Szostak’s case the monounsaturated variety) and other amphiphiles that constitute them. If the wrong choice is made, the vesicles cannot even form. What is more, vesicle formation and stability depend critically on fine-tuning the optimal concentration of the amphiphiles in an aqueous environment carefully controlled for pH (buffers), salinity and temperature. Those clays and minerals must be scrupulously clean. The melting point of the fatty acids employed in the vesicles must also be considered. In a real life laboratory environment, the vesicles must, in some cases, be repeatedly frozen and thawed and, as highlighted above, their physical extrusion through pores must be carried out. Even then, vesicles of only the desired size are selected to optimise the process. Creating the vesicles from scratch requires advanced knowledge of the chemical properties of the amphiphiles making them up. After all, the mantra of the biochemist is ‘structure dictates function.’ Furthermore, Szostak’s progress depends upon the prior work of thousands of intelligent minds across the human world, and from many generations.

Sic transit gloria mundi!

This analysis shows that it is unreasonable to expect life to have arisen without an intelligent agency.

I believe this agency to be a personal being, infinitely good, infinitely powerful and infinitely well funded; the God uniquely revealed in the Bible.

Totality.

 An essay dedicated to the Faithless Generation.

For since the creation of the world God’s invisible qualities- his eternal power and divine nature –have been clearly seen, being understood from what has been made, so that people are without excuse. For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools..

Coincidence is God’s way of remaining anonymous

                                                                      Albert Einstein (from The World As I See It)

When the Moon formed, it was much closer to the Earth, and has been steadily retreating as the energy of its orbital motion has gone into stirring up tides….. Just now the Moon is about 400 times smaller than the Sun, but the Sun is 400 times farther away than the Moon, so that they look the same size on the sky. At the present moment of cosmic time, during an eclipse, the disc of the Moon almost exactly covers the disc of the Sun. In the past the Moon would have looked much bigger and would have completely obscured the Sun during eclipses; in the future, the Moon will look much smaller from Earth and a ring of sunlight will be visible even during an eclipse. Nobody has been able to think of a reason why intelligent beings capable of noticing this oddity should have evolved on Earth just at the time that the coincidence was there to be noticed. It worries me, but most people seem to accept it as just one of those things.

                                                                   John Gribbin (from Alone in the Universe)

The noted science writer and astrophysicist, Dr. John Gribbin, raises an interesting point at the end of the excerpt from his 2011 book, Alone in the Universe, quoted above. He describes the coincidence of a total solar eclipse and the emergence of a global human technical civilization as something that ‘worries’ him. I can well understand that position given the inadequacy of the blind forces of Darwinian evolution to explain why these events are coincident in cosmic time. But that’s only an issue if one assumes biological evolution to be watertight. A more rational, and dare I say, compelling answer to Gribbin’s conundrum is that these events are not mere coincidences but were pre-ordained to occur in a unique window of cosmic history to reveal the attributes of an all powerful Creator; a personal God who, like a great king, wishes to demonstrate His omnipotence to an unbelieving population.

Such a world view, which is currently counter to the prevailing secular corpus of scientific thought, would be strengthened if other attributes of the Sun were found to be odd, peculiar or even unique. Intriguingly, great advances in our knowledge of the Sun over the past 30 years has yielded a solid body of evidence pointing to the possible uniqueness of our Sun, the yellow star that has presided over the extraordinary allegory of events that culminated with a global human technical civilization in the present epoch.

                                                Peculiar formation history

Diligent research over the past century has revealed that stars are not born in isolation but are hatched in their thousands inside enormous clumps of gas and dust. Our Sun was formed from the fragmentation of one such cloud under the auspices of magnetic and gravitational forces that led to the contraction of one cloud fragment, culminating with the ignition of the nuclear fires at the centre of the proto-Sun and the formation of a disc of gas and dust in the plane of the solar equator that would form the elegant planetary system we live in today. Yet the Sun was formed with an unusual assortment of heavy elements that originated in not one but two distinct kinds of supernova events that must have occurred in close proximity to our neonatal solar system to enrich it with those elements. What is more, our solar system was formed during the epoch  when the interstellar medium was maximally enriched with the long-lived radionuclides thorium-232 ( half life 14.1Gyr), uranium-235 (half life 0.704 Gyr) and uranium-238 (half life 4.468 Gyr); elements that provided Earth with the thermal energy to maintain plate tectonics on our planet over geologic time. Without large quantities of these elements, the Earth would have been just another lifeless planet.

But forming the right kind of star and the right kind of planets was still not enough though. Had the Sun and its retinue of planetary bodies remained entangled in the star cluster of its birth for very long, gravitational interactions with nearby stars would have wreaked havoc with our orderly solar system. Moreover, had the Sun formed as part of a binary or multiple star system – as have as many as 70 per cent of sun-like stars in the Galaxy – it would have been game over for a life bearing planet like the Earth, as it would not have able to maintain a stable circular orbit about the Sun over the entire duration of its history. For the Sun and its family of planets to proceed to the next stage of development, it had to be ejected from the cluster of its birth to live in safe isolation from the rest of its stellar siblings.

                                              Peculiar physical properties

In the early 19th century, the German optician, Joseph von Fraunhofer (1787-1826), founded the science of stellar spectroscopy. By attaching a diffraction grating to his achromatic refractor (both of his own design) he was able to demonstrate that stars like Sirius differed significantly from the Sun.

Joseph von Fraunhofer demsonstrating the spectroscope.

Today, we follow in the great optician’s footsteps, employing diffraction gratings to obtain high resolution spectra of a multitude of stars, allowing astronomers to perform a so-called differential element analysis on a large stellar population.These and other techniques have revealed a curious truth about our star, the Sun. While it is easy to find twins of almost any other star, an exact solar twin has yet to be found. And though quite a few stars can be matched to the Sun with respect to its basic parameters like mass, age and luminosity (G2V spectral class), the Sun stands out like a sore thumb with respect to these solar analogues, showing a 20 per cent depletion in certain refractory (non-volatile) elements such as calcium, aluminium, magnesium and silicon; the elements that wound up inside the rocky terrestrial planets of our solar system.

 The Sun, though widely reported to be an ‘ordinary star’ is actually more massive than 95 per cent of all other stars in the Galaxy. The vast majority of stars, the teeming multitudes of red and brown dwarves, are too cool to hold planets at a safe distance from their fiery surfaces in order that liquid water could be profitably maintained on their surfaces over the aeons. Such stars would need to spawn planets very close in – typically an order of magnitude closer than Mercury is to our Sun – causing them to become tidally locked. This means that they would keep the same face to their parent stars in much the same way our Moon does while orbiting the Earth. This scenario would render life incredibly difficult on such planets. After all, the permanently illuminated hemisphere would be incinerated while the other would be in a perpetual frigid darkness. Lower mass stars, by their nature, emit less ultraviolet (UV) radiation too – a plus you might think – until you learn of how important UV radiation is for generating and sustaining the ozone layer. And no ozone layer would make life very difficult indeed on the landmasses of any putative world orbiting these low mass stars.

But there are yet other perils that attend stars with lower masses than the Sun. In the summer months, I use my 3 inch classical refractor to project an image of the Sun on a piece of white cardboard or by using a full-aperture solar filter. More often than not, I can make out small sunspots – regions of intense magnetic activity that correspond to cooler regions of the solar photosphere – that make an otherwise bland solar disc all the more interesting to observe. Sunspots though, are also strongly correlated with flare activity and it is not an inconsiderable fact that stars even a little lower in mass than the Sun have significantly higher activity in this regard. Ongoing solar research suggests that during sunspot maximum (which follows a roughly 11 year cycle) our Sun already has the ability to inflict potentially serious damage to living cells, as well as hampering human telecommunication  systems, so that any significantly greater activity would prove disastrous for life on Earth in general and human civilization in particular.

Sol, as it appeared through the author’s 3-inch Fraunhofer refractor  on the sunny afternoon of May 7, 2013.

The tiny fraction of stars in the Galaxy larger than the Sun have very short lifetimes (scaling with mass as M^-2), insufficiently long to allow even microbial life (if it exists at all) to start the process of heavy metal concentration – which include the so-called ‘vital poisons,’ as well as the heavy metal deposits needed to sustain a high-technology society – in their planet’s crust.

                                                           Peculiar stability

How does flare activity correlate with stellar age? It turns out that solar flaring has continued to decline over time, reaching a minimum in the present epoch, roughly half way through the life of our star and dovetailing nicely with the emergence of humanity in the solar system. What’s more, sensitive measurements reveal that our star varies less in luminosity (typically by less than 0.1 per cent) than any known star.

                                                       Peculiar kinematics

In 2008, a team of astronomers led by Charles Lineweaver based at the Australian National University, conducted a study on a large body of stars taken from the Hipparcos archive and discovered that the Sun has a more circular orbit than 93 per cent of other stars in the distribution. Safely tucked away between spiral arms near the co-rotation axis of our Galaxy (a peculiarly stable place to be!), some 27,000 light years from its centre, we live on a planet spared the deadly effects of short wave radiation that have surely sterilised the down town regions of the Milky Way. Out here, in Galactic suburbia, we move around the centre of the Galaxy once every 0.25Gyr, enjoying transparent, dark skies that allow us to look all the way back in time to the earliest epochs in cosmic history, so enabling humans to elucidate the physical events that shaped the unfolding cosmos in which we find ourselves in.

Stars not only move within the plane of the Milky Way’s thin disc but oscillate up and down as they orbit the Galactic centre. Many years of kinematic studies conducted by astronomers show that its amplitude of oscillation is smaller than many stars in the solar neighbourhood which makes the solar system less susceptible to gravitational perturbations that could potentially destabilise established planetary orbits. Indeed, according to the stellar astronomer, Dr. Guillermo Gonzalez, the Sun’s kinematic attributes are more reminiscent of a young star than one that is 4.57 billion years old!

                                                            Not forever!

As I have attempted to outline thus far, it seems patently clear that the Sun is a very unusual star enjoying a rather unusually stable phase in its life. Over billions of years since its birth, the Sun has grown steadily brighter and life on Earth, particularly the green plants, have worked to compensate for the Sun’s increasing luminosity by removing more of the greenhouse gases (particularly carbon dioxide and water vapour) from the Earth’s atmosphere. But the unchanging laws of physics that govern the Sun’s evolution are the same yesterday, today and tomorrow. This means that the Sun is going to continue to brighten and heat the Earth’s surface. But the levels (currently 392ppm) of carbon dioxide needed to conduct photosynthesis are already close to the minimum necessary (~150ppm) to sustain vigorous plant growth. Clearly, the current situation cannot be maintained indefinitely. Likewise, as it continues to evolve (and stars really do evolve because there is a robust physical theory underpinning that process), flare activity will increase to a point where large animal life cannot be sustained. Clearly therefore, we are living in the best of times.

                                               Just one of those things….

I suppose one could always shrug one’s shoulders and say something like, “that’s a strange coincidence,” or “it’s mere chance.” But, these answers are not very satisfying to a curious intellect; an intellect hard wired to spot patterns. Cast your mind back once more to the exquisite geometry of a total solar eclipse. A few million years ago, the Moon’s apparent diameter was larger than the Sun’s and the non-human primates – Homo Erectus or some such – that inhabited the Earth at that time, lacked the sophistication – both mentally and spiritually – to appreciate the event. In a few million years hence, the Moon will be smaller than the Sun’s face and the Earth will be unfit for human habitation. Only at a time sandwiched neatly between these epochs did creatures with the necessary cognitive capacities emerge on the scene to understand the significance of this alignment, allowing them to deduce both the geometry and scale of the solar system. Even the mind-boggling logic of Einstein’s theory of general relativity was confirmed during a solar eclipse.

Do you really think these solar peculiarities are just coincidences? How many coincidences and peculiarities does one need to convince one of a greater, underlying truth about the Sun and our relationship with it? And where does Darwinian evolution – the ‘blind watchmaker’ – fit into all of this?

Thank goodness for small mercies!
