• Classically, black holes are perfect absorbers but do not emit anything; their physical temperature is absolute zero. However, in quantum the-ory black holes emit Hawking radiation with a perfect thermal spec-trum. This allows a consistent interpretation of the laws of black hole mechanics as physically corresponding to the ordinary laws of thermo-. The Black Hole by Alan Dean Foster was a science fiction novel for me. I mean that it was predictable for me because it involved things like space ships, robots, lots of technology that the author must explain to the reader, and a large chunk of the story being devoted completely to /5(17). Black Holes and Thermodynamics Stationary black hole ↔Body in thermal equilibrium Consider an ordinary system composed of a large number of particles, such as the gas in a box. If one waits long enough after one has filled a box with gas, the gas will “settle down” to final state of thermal .   We review the present status of black hole thermodynamics. Our review includes discussion of classical black hole thermodynamics, Hawking radiation from black holes, the generalized second law, and the issue of entropy bounds. A brief survey also is given of approaches to the calculation of black hole entropy. We conclude with a discussion of some unresolved open by:

The radiation is purely thermal. The Hawking temperature of a black hole is such that the Wien wave length corresponds to the radius of the black hole Size: KB.   Originally Answered: What are some good books on black holes? You know, Stephen Hawking is the one who has spent his major part of life in doing research on black holes. Then probably his books would contain the stuff you want on black hole, for example A brief history of time, although this book doesn't contain everything about black hole but still this topic is a major part of the book.

anism by which the black hole produces thermal radiation, its nature and origin, and the energetics of back-reaction on the hole are reviewed. The thermal states of quantum holes are also treated using the theory of thermal Green functions, and the entropy of the hole is shown to be related to the loss of information about the quantum.   Kip S. Thorne is one of the most important researchers in gravity and black holes.

They're so weird, Stephen Hawking says that much of what we know about them is probably fundamentally we do know is they have so much gravity, not even light can escape. And they can be as small as a single atom, but still have the mass of a epitomise 'the fear of the unknown', but don't worry - we can all sleep a little easier .
