Web2 giu 2016 · First, the Unruh and Hawking radiation aren't quite "the same thing". They have a similar origin and the Unruh radiation may be considered a flat space (large black hole) limit of the Hawking radiation. Now, the near-horizon metric of an extremal black hole is A d S 2 × S 2 while for a non-extremal one, the A d S 2 is replaced by the Rindler space. Web13 ago 2024 · Aggiornato il 13 agosto 2024.

WebHawking radiation (also known as Bekenstein-Hawking radiation) is a thermal radiation with a black body spectrum predicted to be emitted by black holes due to quantum effects. WebSeth Lloyd calculated the computational abilities of an "ultimate laptop" formed by compressing a kilogram of matter into a black hole of radius 1.485 × 10 −27 meters, concluding that it would only last about 10 −19 seconds before evaporating due to Hawking radiation, but that during this brief time it could compute at a rate of about 5 × 10 50 …
WebAs a black hole emits this thermal radiation one would expect it to lose mass. This in turn would increase the surface gravity and so increase the rate of emission. The black hole would therefore ...
