Stephen Hawking: 'There are no black holes' - Science - News - The Independent
Stephen Hawking has produced a "mind-bending" new theory that argues black holes do not actually exist - at least not in the way we currently perceive them.
Instead, in his paper, Information Preservation and Weather Forecasting for Black Holes, Hawking proposes that black holes can exist without 'event horizons', the invisible cover believed to surround every black hole.
During a previous lecture, 'Into the Black Hole', Hawkins described an event horizon as the boundary of a black hole, "where gravity is just strong enough to drag light back, and prevent it 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.”
But now, Hawking is proposing 'apparent horizons' could exist instead, which would only hold light and information temporarily before releasing them back into space in 'garbled form', Nature has reported.
