Hawking radiation is emission released outside a black hole's event horizon according to a model developed by Stephen Hawking in 1974. [1] The radiation was not predicted by previous models which assumed that once electromagnetic radiation is inside the event horizon, it cannot escape.

At this stage, a black hole would have a Hawking temperature of T P / 8π (5.6 × 10 30 K), which means an emitted Hawking particle would have an energy comparable to the mass of the black hole. Thus, a thermodynamic description breaks down. Such a micro black hole would also have an entropy of only 4 π nats, approximately the minimum ...
In 1974, Hawking predicted that black holes might not be the bottomless pits we imagine them to be -- and now, there may be evidence to support that theory.
Stephen Hawking provided a ground-breaking solution to one of the most mysterious aspects of black holes, called the "information paradox." Black holes look like they 'absorb' matter. Every time a ...
Black holes are often viewed as inescapable vortexes, but, in a recent talk at Harvard University, Stephen Hawking suggested they might be more like portals than prisons, reports the Boston Globe. ...
If black holes evaporate via Hawking radiation, a solar mass black hole will evaporate (beginning once the temperature of the cosmic microwave background drops below that of the black hole) over a period of 10 64 years. [152] A supermassive black hole with a mass of 10 11 M ☉ will evaporate in around 2×10 100 years. [153]
While the black hole itself is invisibly dark, astronomers managed to observe the “point-of-no-return” precipice around its edge – the boundary scientists call the Event Horizon – made up ...
