Stephen Hawking: Black holes do not exist
The internationally renowned theoretical physicist claims that they do not exist by their defining characteristic of an ‘event horizon'
Famous physicist Stephen Hawking made surprising statements on Friday when he said that black holes do not actually exist in the way they were previously defined, reported UK-based daiy The Independent.
The internationally renowned theoretical physicist, who had previously believed in the concept of black holes, is now claiming that they do not exist by their defining characteristic of an “event horizon.”
In a previous paper, “Into a Black Hole,” Hawking explained a black holes’ event horizon, or boundary, is the area ‘where gravity is just strong enough to drag light back and prevent it from escaping.”
“Falling through the event horizon is a bit like going over Niagara Falls in a canoe," he said. "If you are above the falls, you can get away if you paddle fast enough, but once you are over the edge, you are lost. There's no way back.”
"As you get nearer the falls, the current gets faster. This means it pulls harder on the front of the canoe, than the back. There's a danger that the canoe will be pulled apart. It is the same with black holes.”
However, Hawking is now going back on his previous convictions, claiming that black holes can exist without the so-called ‘horizons,’ meaning that light and information could be held temporarily before being released back into space; sentiments he explained in his latest paper, “Information Preservation and Weather Forecasting for Black Holes.”
In it, he concludes that because of absence of the event horizons, there are no black holes, “in the sense of regimes from which light can't escape to infinity."
Hawking also said that the new scientific proposal still aligns with quantum mechanics and general relativity theories.
He told Nature journal: “There is no escape from a black hole in classical theory, but quantum theory, however, “enables energy and information to escape from a black hole.”
The respected physicists’ work was a result of his attempts to reconcile what scientists call the “black-hole firewall paradox,” in which the definition of a black hole was inconsistent with two pillars of modern physics, general relativity and quantum theory.
