The problem with The Three Body Problem

The possibility of love in a universe of terror.

Netflix.

If you are prone to nightmares or paranoia you might want to steer clear of the first season of Netflix’s sci-fi epic, 3 Body Problem. Adapted from Cixin Liu’s multi award-winning Remembrance of Earth’s Past trilogy, the story starts in the Chinese Cultural revolution of the 1960s and ends twelve million years in the future. Mercifully the narrative is non-linear, so we’re spared a minute-by-minute account. It begins as a global mystery - scientists all over the planet are taking their own lives in mysterious circumstances – and ends with advanced alien weaponry collapsing the universe to a single dimension. All based on a true story, apparently. 

Why the paranoia? At the heart of both Liu’s novels and the Netflix adaption, is a particularly terrifying solution to the Fermi Paradox. Enrico Fermi was one of the physicists working on the Manhattan Project (played by Danny Defari in the Christopher Nolan depiction of it in Oppenheimer), who presented his now famous paradox to his colleagues at Los Almos. The paradox goes like this: in a galaxy of billions of stars similar to our sun it is almost certain that advanced alien life is out there, and yet we have not received any convincing evidence of their existence. This, it seems, requires some explanation. 

Interestingly, this question was also the starting point of C.S. Lewis’ sci-fi cycle The Cosmic Trilogy, and lies behind the title of its first book, Out of the Silent Planet. According to Lewis, the Earth has been placed under a kind of galactic quarantine, as a result of the fall of humanity, nothing and no-one is allowed in or out. The solar system is teeming with life, but we are partitioned from it. We’ve been blocked from the cosmic WhatsApp group for breaching behaviour standards. The aliens are out there but they’re keeping clear. We are the silent planet. 

Cixin Liu however opts for a darker and more disturbing solution to Fermi’s question, which provides the title of the second book in his trilogy, The Dark Forest. The aliens are out there, but it is not we who have been silenced, it is they who are silent. The universe, according to this theory, is like a forest filled with predators and the most sensible thing any intelligent life can do is hide in the undergrowth to avoid attracting attention. Telegraphing our existence into the void by sending signals into space is to naively invite destruction. Alerting the universe to our presence is an act of existential self-harm. The universe is silent because everyone is hiding. For Lewis the universe shone with a love from which we had been excluded, for Liu it is saturated with malice from which we should exclude ourselves. 

If Nietzsche was right, that we can survive any how as long as we have a why, then Liu’s characters are saddled with the opposite burden: endless hows and no why. 

It probably isn’t too much of a spoiler to acknowledge that the inevitable happens. Aliens are contacted. They do make plans to invade.  It is arguably a bit more of spoiler to give away exactly how this happens. The distance between them and us is so vast that, even travelling at one percent lightspeed it will take their invasion fleet four hundred years to get here. And in the meantime, just to ensure we can’t mount any meaningful defence against them, they fold a planet-sized computer into a photon-sized particle and send it to earth to sabotage all technological development. They can watch our every movement, overhear every conversation. We know they are coming and can do almost nothing about it. The bodies of suicides hanging in the fog from every lamppost lining the Thames underline the overriding despair. It is deliciously bleak. I did not sleep well after watching it. 

Liu’s brilliance is not in doubt. The Netflix adaptation can barely capture the fireworks of creative inventiveness that crowd every page of his books (indeed the producers even dropped the definitive article from the book's title). In China, his fellow science fiction writers simply call him ‘Da Liu’ (Big Liu) in honour of his works of towering imagination. But I can’t help feeling that the overall atmosphere of The Three Body Problem is an example of what the theologian Carver Yu, another Chinese author, claimed characterised our culture: technological optimism and literary despair. Liu’s characters respond to the relentless encroachment of a malevolent universe with endless technological innovation. They possess an inexplicable will to survive in a cosmos where no one would wish to live. If Nietzsche was right, that we can survive any how as long as we have a why, then Liu’s characters are saddled with the opposite burden: endless hows and no why. They are thirsting for purpose while drowning in applications.  

What struck me most watching the Netflix adaptation was that it seemed to extend the experience of living in a post-industrial society to the whole universe. Our sense that many of the organisations to which we owe our allegiance are clever but inhuman, technologically advanced yet amoral, is expanded to fill the farthest reaches of our imagination. Of course, human beings have always done this. Our ancestors saw faces in the clouds and gods in the constellations. We peer into the emptiness of the skies and populate them with our fears and hopes. Faced with the Copernican revolution and the rise of science, Pascal anticipated the cosmic horror of Liu by nearly four hundred years in confessing, ‘the eternal silence of these infinite spaces fills me with dread.’ The Three Body Problem, unlike Lewis who saw planet Earth as an aberration in an otherwise benevolent cosmos, takes our global technological arms-race and makes it the ultimate reality of the entire universe. 

The crucial point is that we are not obliged to populate the blank canvas of the cosmos with the malice of Liu or the terror of Pascal.

The Three Body Problem then, like much science fiction, is a valuable and ingenious thought-experiment, but not one I wish to dwell on for too long. I prefer to contrast it with something closer to the cosmology that informed C.S. Lewis. One in which the core operating principle of everything is not the necessity of violence, but the indispensability of love. Something akin to Teilhard de Chardin’s assertion that in the dreams, wonder, exploration and imagination of love, a thread is woven that reaches the very heart of the universe. Despite all appearances to the contrary, love is the deepest reality of all.  

This assertion is problematic in many ways. Not least in the face of the evident brutality and violence that traumatises human life. But even more fundamentally than that, how can we intelligibly assert the primacy of love while gazing out at a vast indifferent universe? What are we to do with those infinite silent spaces that so terrorised Pascal? 

Perhaps we can try another thought-experiment. This one is drawn from the work of philosopher Chris Barrigar. He calls it the Agape/Probability account. The full argument is long and detailed, so there is no time to explain it all, but the broad brushstrokes are enough. Here’s the thought. What if we live in exactly the kind of universe required to produce creatures who can freely choose to live with self-giving love? They couldn’t be forced or coerced into it, but the conditions could be set in place that would lead to the emergence of such beings. The principles of ‘asymptotic’ statistics suggest that some things may not be determined but they can be so highly probable as to be inevitable. Barrigar asserts that the appearance of a species with the capacity to love was a cosmic inevitability. What is required to turn this possibility into something pretty much certain? Two things – lots of opportunities and lots of time. In other words, with apologies to Carl Sagan, if we want creatures capable of love, we need to build a universe. 

Of course, a universe like that – a universe like ours – will throw up many other things in addition to love: violence, rock music and apples pies. But the crucial point is that we are not obliged to populate the blank canvas of the cosmos with the malice of Liu or the terror of Pascal. The cold silence of space does not in itself contradict our intuitive sense that the capacity to love is somehow ultimately significant. On the contrary, when we look at the vast distances between the stars, we could be looking at the minimal amount of spaciousness required to bring about beings with the capacity for self-giving love. At the very least, it’s a thought-experiment worth trying.

Getting hitched should benefit more than the advantaged

Marriage’s decline impacts outcomes for all.

Of all the dramatic changes to Britain in the last half century, one of the least discussed is the extraordinary decline in marriage.  

The marriage rate has fallen by two-thirds in the last 50 years. It was just above six per cent in 1972 and has now been under two per cent since 2017. 

This remarkable decline has corresponded with a rise in a relatively new relation type: cohabitation. Cohabitation was extremely uncommon before the 1960s, and even by 1986 just 10 per cent of new mothers were cohabitants. It is, however, rapidly becoming the mainstream. Now 35 per cent of babies are born to cohabiting mothers, and the total number of UK cohabiting couples increased from 1.5 to 3.7 million between 1996 and 2022.  

Much of this is due to couples delaying marriage: 84 per cent of religious and 91 per cent of civil marriages are now between couples that already live together, and the average age when first marrying has climbed by 10 years since the early 1970s. But it is also due to many more couples not marrying at all. 

Opinions understandably differ on this social transition away from marriage and towards cohabitation. It is a point of progress worth celebrating that the previous societal shunning of those, especially women, who had children outside of marriage has been left in the past. However, such progress has not been without consequences. Cohabitations are less stable, on average, than marriages. Cohabiting parents are around three times as likely to separate in the first five years of their children’s life as married couples.  

This stability is not simply because wealthier, more highly educated people tend to have stable families and also tend to marry. Studies by World Family Maps and the Marriage Foundation have shown marriage to be a larger factor in family stability than either education or income.  

Nor does the stability come from couples staying together miserably.  Studies undertaken in 2017 and 2024 looked at the outcomes of couples 10 years on from considering their relationships to be ‘on the brink’. In the initial study, while 70 per cent of cohabiting couples had separated in the decade since considering themselves ‘on the brink’, 70 per cent of the married couples had remained together. Perhaps even more crucially, just seven per cent of those married couples that had stayed together were unhappy in their relationship a decade on. The 2024 study found none of the sample of married couples that had stayed together were still unhappy 10 years on. For those that had stayed together, things had improved. 

This family instability that the decline of marriage has caused is also unevenly distributed. Affluent couples – often those most likely to criticise the concept of marriage – are much more likely to marry than disadvantaged ones.  

Looking at socioeconomic groups, seven in ten mothers from the most advantaged group are married, while just a third of those from the two most disadvantaged groups are. The effect is geographic, too. Institute for Fiscal Studies research has found parents having children are more likely to be married if they are living in better educated areas. For the advantaged, it is compassionately affirmational to suggest that every relationship is equal, even though the advantaged themselves choose the most secure option of marriage: a hypocrisy only tolerated due to the potent fear of seeming judgemental. 

The consequence of this is deepening inequality: disadvantaged families are rendered more likely to breakdown, while children from affluent backgrounds are disproportionately likely to enjoy the ‘the two-parent privilege’, the substantial emotional and developmental advantages of growing up in a stable home. Melissa Kearney coined the phrase, and her evidence shows how children grow up, on average, to have better educational outcomes, better emotional and physical wellbeing, and higher incomes if they are raised in two-parent homes. 

Stable families are foundational to a stable society, and marriage is crucial to stable families.

So, why are marriage rates so much higher among wealthier couples than poorer ones, and why is this gap growing? 

We can isolate three reasons in particular, each more solvable than the last.  

Most challenging is the feedback loop effect: people whose parents, role-models, and friends have not married are unlikely to do so themselves. The demographic trend compounds itself.  

Second, and easily addressable if only the will was there, is the public messaging effect: politicians – and to some extent celebrities – have consistently told the public that marriage is unimportant. In 2017, Marriage Foundation research found that it had been a decade since a cabinet member had discussed marriage in a speech. This has hardly changed in the years since. In 2024, the only major party whose manifesto even mentioned marriage was Reform; even then the focus in the relevant section seemed to be less on marriage and more on getting ‘people trapped on benefits back into the workplace’. 

Third is the cost of weddings. A quick flick through top wedding magazines suggests that the average wedding costs upwards of £20,000. Survey evidence from both Marriage Foundation and the Thriving Center of Psychology have found that most young people view weddings as unrealistically expensive. 

This financial problem is solvable: much of the costs relate to venue hire. Unless they are having a religious marriage, a couple will need to find a venue that has gone through the bureaucratic process of becoming an ‘approved premises’. The cheapest of these are register offices which, including all expenses, still cost about £500. 

This is eminently mendable. The Law Commission proposal to reorganise wedding law around the officiant, not the venue, opens the door for a future of more affordable weddings by removing the regulatory barrier. It will also bring the law in line with that of other home nations. 

This proposal will not work by itself, though, it will need to be supported by creativity in wedding planning.  

Wedding costs can be substantially reduced by taking a DIY approach. Food, drinks, and decorations can often be coordinated amongst enthusiastic (and appropriately competent!) guests.  

Booze free weddings are a growing phenomenon, and especially good for weddings with children.  

Such ‘group-effort’ approaches often have a unique feel thanks to the high participation of guests, and people are more likely to remember events that they feel a sense of ownership of, having helped make them happen. 

Alongside this is a recommendation by the Centre for Social Justice. It proposes subsidising the necessary statutory fees for the poorest couples, up to £550 per couple. An inexpensive and hugely beneficial adjustment to improve wedding accessibility for the least fortunate.  

Stable families are foundational to a stable society, and marriage is crucial to stable families; perhaps it is time for all of us to make tying the knot easier.
