The Universe is so unimaginably big, and it’s positively teeming with an almost infinite supply of potentially life-giving worlds. So where the heck is everybody? At its heart, this is what’s called the Fermi Paradox: the perplexing scientific anomaly that despite there being billions of stars in our Milky Way galaxy – let alone outside it – we’ve never encountered any signs of an advanced alien civilisation, and why not? It’s a decent question, and one that generations of scientists and thinkers have grappled with since the paradox was formulated decades ago. Some suggest aliens might be hibernating, or that something mysterious is preventing their evolution from taking place. Or maybe they just don’t want anything to do with us? Physicist Alexander Berezin has a new theory – and to some, it might be just a bit disturbing.
