Some physicists think that we need to seriously update how we think of black holes. A theory that suggests they may actually resemble giant 'fuzzballs' would do just that.
Some physicists think that we need to seriously update how we think of black holes. A theory that suggests they may actually resemble giant "fuzzballs" would do just that.In the 1970s, Stephen Hawking discovered something impossibly wrong with black holes: It was mathematically possible for them to shrink or even disappear. If a black hole disappeared, that would mean that everything it had sucked in disappeared too.
That shrinking results in a super-dense region of space-time that gobbles up everything that encounters it called a black hole. Though don’t let fear of getting sucked into a black hole keep you up at night, says Lia Medeiros, a National Science Foundation postdoctoral fellow at the Institute for Advanced Study; you’d have to get really close for that to happen. From far away, a black hole behaves like any other object with a lot of gravity, like a star.
“It seems to an external observer that the black hole is actually losing mass, one particle at a time,” says Pacucci. That would result in the black hole losing a tiny bit of the information associated with that particle, and information is supposed to always be conserved. Therein lies the paradox. It’s also worth noting that this scenario could only happen on a very small scale, because there aren’t enough free-floating anti-particles to happen en masse.
