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 chapter discusses an aspect of black holes' behavior that Stephen Hawking discovered in the 1970s. According to earlier theories, black holes can only become larger, and never smaller, because nothing which enters a black hole can come out. However, in 1974, Hawking published a new theory which argued that black holes can "leak" radiation.
The Thorne–Hawking–Preskill bet was a public bet on the outcome of the black hole information paradox made in 1997 by physics theorists Kip Thorne and Stephen Hawking on the one side, and John Preskill on the other, according to the document they signed 6 February 1997, [1] as shown in Hawking's 2001 book The Universe in a Nutshell.
See Stephen Hawking through the years: Acoustic black hole. To test this prediction, Steinhauer created an analogue black hole using extremely cold atoms trapped in a laser beam. When he applied a ...
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 ...
Hawking discusses black hole thermodynamics, special relativity, general relativity, and quantum mechanics. Hawking also describes his life when he was young, and his later experience of motor neurone disease. The book also includes an interview with Professor Hawking. [2]
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.
This idea suggests that Hawking radiation stops before the black hole reaches the Planck size. Since the black hole never evaporates, information about its initial state can remain inside the black hole and the paradox disappears. But there is no accepted mechanism that would allow Hawking radiation to stop while the black hole remains macroscopic.
