In physics, black hole thermodynamics [1] is the area of study that seeks to reconcile the laws of thermodynamics with the existence of black hole event horizons.As the study of the statistical mechanics of black-body radiation led to the development of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the ...
Strange Days at Blake Holsey High (also known as Black Hole High) is a science fiction television series which first aired in North America in October 2002 on Global TV.It is set at the fictional boarding school of the title, where a Science Club (five students and their teacher) investigates mysterious phenomena, most of which is centered on a wormhole located on the school grounds.
Robert M. Wald (textbook, black-hole perturbations, black-hole thermodynamics, electric fields outside a black hole, quantum field theory in curved spacetimes), Arthur Geoffrey Walker (Fermi–Walker derivatives, Robertson–Walker metric), Mu-Tao Wang (quasilocal mass-energy), Joseph Weber (gravitational-wave detectors),
Black Holes and Beyond; An Answer to Everything; An extensive online companion site was produced to accompany the documentary. The online companion covers history of cosmology, unanswered questions and other topics related to the program. It was designed to function as both a supplement to the series and a stand-alone web piece.
In 1972, Bekenstein was the first to suggest that black holes should have a well-defined entropy. He wrote that a black hole's entropy was proportional to the area of its (the black hole's) event horizon. Bekenstein also formulated the generalized second law of thermodynamics, black hole thermodynamics, for systems including black holes.
A two-hour episode examines what scientists have learned about M87*, the supermassive black hole in the supergiant elliptical galaxy Messier 87 (also known as Virgo A or NGC 4486). M87* is the first supermassive black hole photographed by the Event Horizon Telescope.
A British theoretical physicist and cosmologist whose scientific work includes the Penrose–Hawking singularity theorems, the prediction that black holes emit radiation, and a theory of cosmology unifying the general theory of relativity and quantum mechanics. – Subject: Bill Hamilton: Presenter: Richard Dawkins
According to the Bekenstein bound, the entropy of a black hole is proportional to the number of Planck areas that it would take to cover the black hole's event horizon.. In physics, the Bekenstein bound (named after Jacob Bekenstein) is an upper limit on the thermodynamic entropy S, or Shannon entropy H, that can be contained within a given finite region of space which has a finite amount of ...
