Hawking radiation is black body radiation released outside a black hole's event horizon due to quantum effects 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.
This book is a collection of essays and lectures written by Hawking, mainly about the makeup of black holes, and why they might be nodes from which other universes grow. Hawking discusses black hole thermodynamics , special relativity , general relativity , and quantum mechanics .
In 1973–1975, Stephen Hawking showed that black holes should slowly radiate away energy, and he later argued that this leads to a contradiction with unitarity. Hawking used the classical no-hair theorem to argue that the form of this radiation—called Hawking radiation —would be completely independent of the initial state of the star or ...
In 1974, Stephen Hawking predicted that black holes might not be the bottomless pits we imagine them to be. According to Hawking's calculations, some information might escape black holes in the ...
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 never stopped trying to unravel the mysteries surrounding black holes -- in fact, he was still working to solve one of them shortly before his death. Now, his last research paper ...
Hawking created Stephen Hawking: Expedition New Earth, a documentary on space colonisation, as a 2017 episode of Tomorrow's World. [212] [213] In August 2015, Hawking said that not all information is lost when something enters a black hole and there might be a possibility to retrieve information from a black hole according to his theory. [214]
In 1974, Stephen Hawking made one of his most famous predictions: that black holes eventually evaporate entirely.According to Hawking's theory, black holes are not perfectly "black" but instead ...
