Are black holes the ruthless killers we’ve made them out to be? Samir Mathur says no. According to the professor of physics at Ohio State University, the recently-proposed idea that black holes have “firewalls” that destroy all they touch has a loophole.

In a paper posted online to the arXiv preprint server, Mathur takes issue with the firewall theory, and proves mathematically that black holes are not necessarily arbiters of doom. In fact, he says the world could be captured by a black hole, and we wouldn’t even notice.

More than a decade ago, Mathur used the principles of string theory to show that black holes are actually tangled-up balls of cosmic strings. His “fuzzball theory” helped resolve certain contradictions in how physicists think of black holes.

But when a group of researchers recently tried to build on Mathur’s theory, they concluded that the surface of the fuzzball was actually a firewall.

According to the firewall theory, the surface of the fuzzball is deadly. In fact, the idea is called the firewall theory because it suggests that a very literal fiery death awaits anything that touches it.

Mathur and his team have been expanding on their fuzzball theory, too, and they’ve come to a completely different conclusion. They see black holes not as killers, but rather as benign copy machines of a sort.
