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.

Hedgerows are boundaries, but they don’t divide so much as abound

The lines we draw between land and lane connect us.

In May and June, the Devon hedgerows that hold the landscape outside my window are at their fullest, most colourful state of being. Walking the narrow lane that runs away from our house means walking between high hedgerows that rise like soft green walls either side, which really, means walking between ancient living things, because these hedgerows are old. Devon has some of the oldest hedgerows in the country, and so the world – older than the Parish churches whose towers I can see to the south, east, and west, which rise like old-growth trees out of a blanket of green fields.  

Early Bronze Age farmers had to clear woodland to make their fields, and sometimes they left strips of woodland to mark boundaries. These are our oldest hedgerows. They are often found on parish boundary lines, and can support over 2,000 species, also acting as important wildlife corridors for many of them. To roughly date a hedgerow, you count the number of species in a 30m stretch – one species equals 100 years. I have taken to counting random 30m stretches of the hedges that line the lanes near us, and have concluded that we are surrounded by hundreds, in places thousands of years of history – of braided hawthorn and blackthorn, hazel and oak, pink campion and bluebell whose bulbs hide in ancient earth banks that many of the hedgerows sit on.  

Now, in these spring hedges, hawthorn is in blossom, nettles overflow with prickly exuberance, and somewhere deep in the tangle a blackbird tunes its song. The hedges are thick with memory stitched together from centuries of hand-laying, stock-keeping, quiet watching. They are Devon’s old boundaries, but they do not divide so much as abound. Life spills from them: wrens and mice, vetch and violet, and so many more things unseen. These are not just boundaries that mark where other things like fields and roads begin and end then; they are living spaces in their own right. They are pathways for diverse life, they are structures that hold home and shelter, food and safety, they are corridors that contain history and story. They are not just edges, they are the centres of whole lives and worlds.  

Walking here one May morning, I find myself wondering about the lines we draw – between land and lane, but also between ‘us’ and ‘them’ – and whether these lines too might be porous like the hedgerows, which have lived for so long not through independence but through care and relationship.  

The hedges speak paradoxes that I am confronted with every time I go for a walk – of division and abundance, of separateness and connection, of containment and invitation. Lately, I am sitting with these and am coming to understand a threshold that the world offers me: between independence and interdependence. But the truth is I’m not very good at interdependence. I have so often retreated behind the wall of my self-sufficiency, but I am trying to pull that wall down and replace it with a porous and lifegiving hedgerow.  

We draw lines – around ourselves, and between people, nations, beliefs, social classes, politics. Sometimes these lines are for safety, sometimes for exclusion. But the hedgerows tell me that it is possible to hold a line and also to let light and life flow through it and shape it. They tell me that these lines are not end points but invitations to communion.  

In The Left Hand of Darkness, Ursula Le Guin wrote:  

“…I know people, I know towns, farms, hills and rivers and rocks, I know how the sun at sunset in autumn falls on the side of a certain plowland in the hills; but what is the sense of giving a boundary to all that, of giving it a name and ceasing to love where the name ceases to apply? What is love of one's country; is it hate of one's uncountry?”  

Le Guin’s work of science fiction is about otherness and connectedness, with different species having to learn empathy in order to collaborate and communicate. The darker the events in the book, the brighter the hope and relationship. The book feels like it was written for now, for this world.  

On my hedge-edged walks I am in the presence of lives so unlike mine – plants, creatures, the people who have tended and cared for these hedges through generations.

In a world whose people are persecuted, othered, tired, it is easy to believe that the way of things is division and separation. But hedgerows suggest another way to live: layered, porous, complex and interconnected, creating space not just for encounter but for new life through that encounter. This is how I picture the Kingdom that Jesus speaks about and so often found solace in: a world of intermingling and ever-growing aliveness. I think Jesus would have walked with the hedgerows had he lived in Devon. I think he would have used them to speak of boundary-crossing between heaven and Earth, clean and unclean, Jew and Gentile. I think he would have pointed to them and said, see the tangled beauty of these? They are what the Kingdom is like: held and open, living and lifegiving. This is what I want our future to be too.  

As I walk these old lanes, I am deepening into my hedgerow apprenticeship. I am learning to sink my roots in, to tend boundaries with care, to make space for life. I am also finding that there is nothing in the hedgerows that speaks of self-sufficiency. These ancient, interwoven green features that have defined this landscape are here because of relationships between species. It is easy to talk about the interconnectedness of everything, it is another thing to try to live it – to live like gifts, reciprocity, community, are things that might take the weight of our time. These old hedgerows give me a foothold though – they enliven the overused but hard-to-live idea of interconnection, they show me what it looks like and that it is an approach to life that is patient, strong, sustaining, real.  

When I reach out my hand I can usually find something edible or beautiful in the hedgerow depending on the time of year: blackberry, hazel, oxeye daisy, pennywort, primrose. Yesterday, it was the cow parsley that really caught my attention: its frothing, foaming flourishing. In a few weeks it will give way to what comes next, just as it has always done, just as this world will always do. On my hedge-edged walks I am in the presence of lives so unlike mine – plants, creatures, the people who have tended and cared for these hedges through generations. I am also in the presence of relationship, and of hope.  

Now, with so many crises bearing down on the world, and with anxiety and despair blooming, it is the hedges that remind me of other, older, wiser ways to be. It is the hedges that show me how to root deep into solid ground, and how to reach out to others, and to light, which are so often the same thing.
