One of the biggest paradoxes in astrophysics may finally be solved. The question of what happens to information when it falls into a black hole has vexed physicists for decades, and now a group of researchers claims to have figured it out.

When Stephen Hawking calculated that black holes should slowly evaporate by emitting radiation – now called Hawking radiation – he also created a problem. His work suggested the radiation should be emitted in a way that depended only on the black …
