In the beginning – if there was one

We still don’t know exactly how the universe was created – and, given the limits of the human brain,

Fifty years ago, the American physicist Theodore Maiman created the first laser. At first, it seemed a curiosity; not even its inventors could predict the range of its uses, from eye surgery to DVD players. Likewise, some of this year's scientific advances may be transformative 50 years from now - even though we have no inkling of it today. Many concepts that seem impossible now might be realised in coming decades. But, in a still longer perspective, it is interesting to speculate whether we will reach a limit - if there are some scientific mysteries that will forever baffle us, phenomena that transcend human understanding.

Einstein said that "the most incomprehensible thing about the world is that it is comprehensible". Our brains have not changed significantly since our ancestors roamed the African savannah, so it is remarkable that we have had any success in grasping facets of the cosmos and the quantum - both so remote from the everyday experience. Einstein would have been particularly gratified at how our cosmic horizons have expanded. We now know that our sun is one of several hundred billion stars in our galaxy, which is itself one of many billion galaxies in the range of our telescopes. And this complex panorama emerged from a hot, amorphous "beginning" nearly 14 billion years ago.

In my own subject of astronomy, the controversies of my student days (such as Big Bang versus steady state theory) have now been settled. Some inferences about the early universe are now as firmly evidence-based as anything a geologist could say about the history of the earth - we know what the conditions were a second after the Big Bang. But, as always in science, each advance brings into focus questions that couldn't have been posed before.

The "beginning" itself (if there was one) is still a mystery. In the first fraction of a second, conditions would have been far hotter and denser than we can simulate in the lab. Einstein's theory of general relativity is not enough to understand what banged and why, because it treats space and time as smooth and continuous. We know that no material can be chopped into arbitrarily small pieces; eventually you get down to discrete atoms. Likewise, space may manifest a complicated grainy structure - but this is thought to be on scales a trillion trillion times smaller than atoms.

Yet there may be mysteries, too, at the largest conceivable scales. There could be far more beyond our horizon, as it were, than the vast expanse that our telescopes can observe. There could have been many "Big Bangs" - not just the one in whose aftermath we exist.

Some have speculated that other universes could exist in tandem with ours. Imagine ants crawling around on a large sheet of paper (their two-dimensional universe). They would be unaware of a similar sheet that is parallel to it. Likewise, there could be another entire universe (with three-dimensional space, like ours) less than a millimetre away from us, but we would be oblivious to it if that millimetre were measured in a fourth spatial dimension, while we are imprisoned in just three.

Final frontier

The microstructure of space, and the true extent of physical reality, are among the "open frontiers" of science: intellectual domains where we are still searching for the truth. They are in effect the very large (the cosmos) and the very small (the quantum). But only a tiny proportion of researchers are cosmologists or particle physicists. There is a third frontier, too: the very complex.

Our everyday world presents intellectual challenges just as daunting as those of the cosmos and the quantum, and that is where the vast majority of scientists focus their efforts. It may seem incongruous that scientists can make confident statements about galaxies billions of light years away, while being baffled about matters close at hand that we all care about - common diseases, for instance. But this is because living things, with intricate levels of structure, are far more complex than atoms and stars.

That said, everything, however complicated - breaking waves, migrating birds and tropical forests - is made of atoms and obeys the equations of quantum physics. But the uncertainties of subatomic physics are irrelevant to biologists; even if those equations could be solved, they would not offer the enlightenment that scientists seek.

Each science has its own autonomous concepts and laws. Problems in biology remain unsolved because it is hard to elucidate their complexities, not because we scientists do not understand subatomic physics well enough. This thought takes me back to my initial question: are there intrinsic limits to our understanding, or to our technical capability? Could some branches of science come to a halt simply because we bump up against limits to what the human brain can understand?

Physicists may never understand the bedrock nature of space and time because the mathematics is just too hard; but I think our efforts
to understand very complex systems - above all, our own brains - will be the first to hit such limits.

Perhaps complex aggregates of atoms, whether brains or machines, can never understand everything about themselves. Some aspects of reality might elude us because they are beyond human brains, just as surely as Einstein's ideas would baffle a chimpanzee.

Computers will help: future discoveries may be made by "brute force" rather than by insight. Even back in the 1990s, the higher processing speed of IBM's Deep Blue allowed it to outperform the chess player Garry Kasparov. Astrophysicists can already create a "virtual universe" in a computer and do "experiments" calculating how stars and galaxies evolve, and how our moon formed in a crash between the young earth and another planet.

Brainpower

Despite our limitations, many envisage human beings as the culmination of the evolutionary process. This doesn't seem credible to any astro­nomer, aware as they have been, ever since the work of Charles Darwin, not only of the stupendous time spans of the evolutionary past that led to our emergence, but also of the huge time-horizons extending into the future. Our sun formed 4.5 billion years ago, but it's got six billion more before the fuel runs out.

And the expanding universe will continue, perhaps for ever, becoming (according to the best current long-range forecast) ever colder, ever emptier. So, even if life were now unique to earth, there would be scope for post-human evolution - whether organic or silicon-based - on the earth or far beyond it.
It won't be human beings who witness the sun's demise: it will be entities as different from us as we are from an insect. For them, string theory and brain science might be a doddle, but they will probably be flummoxed by mysteries we cannot even imagine. l

No peace after progress

How the death of the industrial way of life gave us choice – and stoked resentment and fear.

Now that the making of useful and necessary things in Britain is only a shadow of what it once was, we can see more clearly the effects of the Manufacturing Age. The cost was high to the producers of prodigious wealth; a ten-year difference in life expectancy remains between people living in the richest areas and those in Glasgow. The (fleeting, it now seems) visitation of industrialism has made life more comfortable and its dismantling has liberated millions from choiceless occupations. The legacy is one of spectacular improvement, unequally shared.

Perhaps the most dramatic experience of the 20th century was the suddenness with which profligate plenty replaced a skinflint subsistence. Was it the speed of this that distracted us from wondering why, instead of the secure sustenance that generations of needy people had asked of an unyielding economic system, we were offered a promiscuous spillage of goods, promoted with quasi-religious zeal by the converts of a capitalism that had previously delivered to most of its captive workers a life of penury? Such a rapid reversal might have alerted us to changes beneath the surface that elided losses incurred.

The greatest of these was certainly not the extinction of the industrial way of life itself, release from which has been an unqualified blessing. But the transition from relentlessly work-driven lives (in the 1950s, two-thirds of Britain’s workers were still manual labourers) was marked by perfunctory obituaries for the disintegration of industrial communities, with no acknowledgement that, for a century and a half, they had represented the inescapable destiny of the people they sheltered.

Even less recognition was given to the fortitude with which they had borne a long, coercive labour. A way of life, buried without ceremony in the unmarked grave of progress, could not be mourned; and this has generated some social pathologies of our time: resentment over an arbitrary obliteration of industry, disengagement from a party of labour by those it called, like feudal lords, its “own people”, loss of memory of the economic migrants we also were, passing from the goad of industry into the pastures of consumption, and thence into the liberating servitude of technology.

Grief makes no judgement on the intrinsic value of what is lost. Absence of the known and familiar is the object of melancholy in its own right, even if replaced by something immeasurably better. Objectively, there was little to mourn in the vanished industrial way of life: insufficiency and humiliation, malice of overseer and manager, officiousness of poor-law administrator and means-test man. Male industrial workers exhausted in body and spirit, instead of protecting those for whom the power of their hands was the only shelter against destitution, visited similar punishment on their wives and children. There is nothing to be lamented in an end to the penitential life of women, scrubbing not only the red tiles of the kitchen floor, but even an arc of pavement outside the front door; their interception of men on payday before wages were wasted on beer and oblivion; the clenching against joyless invasion of their bodies in the boozy aftermath. But it was the only life they knew, and they adhered to it with grim stoicism and even pride.

There is much to be said for their resistance. The fragile lattice formed by women’s arms was often the only safety net against destitution. Trade unions and friendly and burial societies that shielded folk from economic violence foreshadowed the welfare state and the National Health Service.

The life of labouring people in Britain was strikingly homogeneous, despite diversity of occupation, dialect and local sensibility. There was the same collective experience: terraced house with parlour reserved for celebration or mourning; the three-piece suite, plaster figure on a stand behind the window, chenille curtain against the draught, engraving of The Stag at Bay on the wall; the deal table and Windsor chairs in the living room, the mantelpiece a domestic shrine with clock, candlesticks and pictures of soldiers smiling before they died; the music of cinders falling through the bars in the grate; cheerless bedrooms where husband and wife slept in high connubial state, more bier than bed, where sexual enjoyment was ritually sacrificed as flowers of frost formed on the inside of the window.

And everywhere photographs: wraithlike children with ringlets or in sailor suits, fated never to grow up; weddings in the back garden, a bouquet of lilies and a grandmother in boots and astrakhan hat; the smudged features of a kinsman no one can now identify. Identical memories, too: the shotgun wedding in the dingy finery of a Co-op hall; the funeral tableau around the grave, amid ominous inscriptions of “Sleeping where no shadows fall”; queues outside the ocean-going Savoy or Tivoli to watch Gone With the Wind; the pub where “Vilia” or “The Last Rose of Summer” was hammered out on a discordant piano.

The opening up of such sombre lives might have been expected to call forth cries of gratitude. Instead, a synthetic joy has emanated largely from the same sources that, until recently, offered people grudging survival only, the change of tune outsourced to producers of manufactured delight, purveyors of contrived euphoria to the people – a different order of industrial artefact from the shoes, utensils and textiles of another era.

***

A more authentic popular res­ponse exists beneath the official psalmody, a persistent murmur of discontent and powerlessness. Anger and aggression swirl around like dust and waste paper in the streets of our affluent, unequal society. As long-term recipients of the contempt of our betters, we know how to despise the vulnerable – people incapable of work, the poor, the timid and the fearful, those addicted to drugs and alcohol. Sullen resentment tarnishes the wealth of the world, a conviction that somebody else is getting the advantages that ought to be “ours” by right and by merit.

Rancour appears among those “left behind” in neighbourhoods besieged by unknown tongues and foreign accents: people who never voted for unchosen change, as all political options are locked up in a consensus of elites. “Give us back our country!”
they cry; even though that country is not in the custody of those from whom they would reclaim it. There was no space for the working class to grieve over its own dissolution. If, as E P Thompson said, that class was present at its own making, it was certainly not complicit in its own undoing.

Grief denied in individuals leads to damaging psychological disorders. There is no reason to believe that this differs for those bereaved of a known way of living. The working class has been colonised, as was the peasantry in the early industrial era. When the values, beliefs and myths of indigenous peoples are laid waste, these lose meaning, and people go to grieve in city slums and die from alcohol, drugs and other forms of self-inflicted violence. Though the dominant culture’s erasure of the manufacturing way of life in Britain was less intense than the colonial ruin of ancient societies, this subculture was equally unceremoniously broken. It is a question of degree. The ravages of drugs and alcohol and self-harm in silent former pit villages and derelict factory towns show convergence with other ruined cultures elsewhere in the world.

Depression is a symptom of repressed grief: here is the connection between unfinished mourning and popular resentment at having been cheated out of our fair share, our due, our place in the world. If we are unable to discern our own possible fate in suffering people now, this is perhaps a result of estrangement from unresolved wrongs in our own past. Nothing was ever explained. Globalisation occurred under a kind of social laissez-faire: no political education made the world more comprehensible to the disaffected and disregarded, people of small account to those who take decisions on their behalf and in their name.

Anyone who protested against our passage into this changed world was criminalised, called “wrecker” and “extremist”. The miners’ strike of 1984 was the symbol of this: their doomed fight to preserve a dignity achieved in pain and violence was presented by the merchants of deliverance not only as retrograde, but also as an act of outlawry. Resistance to compulsory change was derided as a response of nostalgics protecting the indefensible, when the whole world was on the brink of a new life. Early in her tenure of Downing Street, Margaret Thatcher, that sybil and prophet who knew about these things, warned that Britain would become “a less cosy, more abrasive” place: a vision confirmed by the Battle of Orgreave – redolent of civil war – and the anguish of Hillsborough.

It is too late to grieve now. Scar tissue has healed over the untreated wound. Though no one expects the ruling classes to understand the distress of perpetual “modernisation”, the leaders of labour might have been able to recognise capitalism’s realm of freedom and a gaudy consumerism that concealed hardening competitiveness and the growth of a crueller, more bitter society.

The ills of this best of all worlds, its excessive wealth and extreme inequality, are on show in hushed thoroughfares of London, shuttered sites of “inward investment”, where the only sound is the faint melody of assets appreciating; while elsewhere, people wait for charitable tins of denutrified substances to feed their family, or sit under a grubby duvet, a Styrofoam cup beseeching the pence of passers-by.

Unresolved feelings about industrialism, enforced with great harshness and abolished with equal contempt for those who served it, are certainly related to the stylish savagery of contemporary life. The alibi that present-day evils are an expression of “human nature” is a poor apology for what is clearly the nature – restless and opportunistic – of a social and economic system that has, so far at least, outwitted its opponents at every turn.
