Matter Sucked in by Black Holes May Travel into the Future, Get Spit Back Out


Black holes may not have singularities at their center. Instead, the matter they suck in may be spit out across the universe at some time in the future, a new theory suggests. Credit: Shutterstock
Black holes are among the most mysterious places in the universe; locations where the very fabric of space and time are warped so badly that not even light can escape from them.

According to Einstein’s theory of general relativity, at their center lies a singularity, a place where the mass of many stars is crushed into a volume with exactly zero size. However, two recent physics papers, published on Dec.10 in the journals Physical Review Letters and Physical Review D, respectively, may make scientists reconsider what we think we know about black holes. Black holes might not last forever, and it’s possible that we’ve completely misunderstood their nature and what they look like at the center, according to the papers.

The edge of Einstein’s physics

Astronomers and physicists have long held that the idea of a singularity simply must be wrong. If an object with mass has no size, then it has infinite density. And, as much as researchers throw around the word „infinity,“ infinities of that kind don’t exist in nature. Instead, when you encounter an infinity in a real, physical, science situation, what it really means is that you’ve pushed your mathematics beyond the realm where they apply. You need new math.
