MEXICO: There was a time when, using the rules of general relativity, you could imagine an infinitely-dense singularity surrounded by a gravitational zone of no-escape called the “event horizon.” These components, with a few other details, described the basic anatomy of a black hole.
The textbook explanation is fairly clear: nothing, not even light, can escape the gravitational clutches of the black hole’s event horizon. It’s a one-way ticket; if an astronaut strays too close to the horizon, they get dragged in, eventually falling to his or her doom via the horrific effects of spaghettification.
Although this is an over-simplification, it was a fairly decent explanation about what was going on. But then, in the 1970′s, British theoretical physics guru Stephen Hawking came forward with his bedrock theory of evaporating black holes. And now, as an extension of his theory, Hawking thinks that black holes aren’t the one-way street the textbooks have led us to believe.
