His mind was truly incomparable.

Stephen Hawking, one of the greatest minds of our lifetime, has passed away – leaving behind a lot of heartbroken science fans.

While he was publishing papers right up until the months before his death, it was in 2016 that he released one of his most talked about journal articles – a long-awaited solution to his black hole information paradox.

In other words, he’d come up with a potential explanation for how black holes can simultaneously erase information and retain it.

The paper was originally published on pre-print site in January 2016, and finally released in a peer-reviewed journal six months later – and it made headlines around the world.

To understand why it was such a big deal, and what the black hole information paradox really is, we need to go back to where it all started.

Our original understanding of black holes, according to Einstein’s generally theory of relativity, is that everything that crosses the event horizon – the boundary of a black hole – is lost forever. Even light can’t escape its clutches, which is why black holes are called black holes (and also why it’s impossible for us to actually see one).

But then in the 1970s, Hawking proposed that radiation actually can escape from a black hole, because of the laws of quantum mechanics. Put very simply, he suggested that when a black hole swallows one half of a particle-antiparticle pair, the other particle radiates away into space, stealing a little energy from the black hole as it leaves.
