SCIENCE: Simulated black hole experiment backs Hawking prediction.
Prof Jeff Steinhauer simulated a black hole in a super-cooled state of matter called a Bose-Einstein condensate.
In the journal Nature Physics, he describes having observed the equivalent of a phenomenon called Hawking radiation – predicted to be released by black holes.
Prof Hawking first argued for its existence in 1974.“Classical” physics dictates that the gravity of a black holes is so strong that nothing, not even light, can escape. So Hawking’s idea relies on quantum mechanics – the realm of physics which takes hold at very small scales.
These quantum effects allow black holes to radiate particles in a process which, over vast stretches of time, would ultimately cause the black hole to evaporate.
But the amount of radiation emitted is small, so the phenomenon has never actually been observed in an astrophysical black hole.
On a long enough timeline, even the survival rate for black holes drops to zero.
