The paper, titled "Information preservation and weather forecasting for black holes," dismisses the idea of an event horizon — the point at which the gravitational pull in a black hole is inescapable — and instead posits a more benign "apparent horizon" exists.
“There is no escape from a black hole in classical theory,” Hawking told Nature.com. Quantum theory, though, “enables energy and information to escape from a black hole."
Hawking's new work hasn't been peer reviewed, but he based in on a talk he gave via Skype at an August meeting at the Kavli Institute for Theoretical Physics in Santa Barbara, Calif.
In an "apparent horizon," there is a surface where light rays attempting to rush away from the black hole's core are suspended.
