100 years ago, Einstein put forth his General Theory of Relativity, and 99 years ago, Karl Schwarzschild came up with the mathematical solution describing a black hole, a solution we now know is not only physically valid, but one that has many examples all across the Universe.

Yet when you consider quantum physics, the matter gets complicated: while you ought to be able to run the laws of physics the same forwards and backwards, a black hole seems to wind up in an irreversibly different state, in the end, from what you started with. That’s the root of the black hole information paradox.

So what’s the solution? Sabine Hossenfelder has the scoop on all the latest research on the topic.
