  • Famed physicist Stephen Hawking caused an uproar with his assertion that black holes do not exist--at least not as people have defined them for the past 40 years. Rather than letting nothing, not even light, escape their grasp, Hawking says that this "point of no return" is a fallacy, and black holes will sometimes let trapped light back out. His idea is a proposed solution to the firewall paradox. The paradox has it that if black holes are as people think, they must be surrounded by rings of fire, though that would violate general relativity.
