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 ...
The entropy of a black hole is given by the well-known Bekenstein–Hawking formula S = k B c 3 A 4 G ℏ {\displaystyle S={\frac {k_{\text{B}}c^{3}A}{4G\hbar }}} where k B {\displaystyle k_{\text{B}}} is the Boltzmann constant , c {\displaystyle c} is the speed of light , G {\displaystyle G} is the Newtonian constant of gravitation and A ...
Conversely, an acceleration of 1 m⋅s −2 corresponds to a temperature of 4.06 × 10 −21 K. The Unruh temperature has the same form as the Hawking temperature T H = ħg / 2πck B with g denoting the surface gravity of a black hole, which was derived by Stephen Hawking in 1974. [7]
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 ...
Jacob Bekenstein was born in Mexico City to Joseph and Esther (née Vladaslavotsky), Polish Jews who immigrated to Mexico. [2] He moved to the United States during his early life, gaining U.S. citizenship in 1968. [3]
In theoretical physics, quantum field theory in curved spacetime (QFTCS) [1] is an extension of quantum field theory from Minkowski spacetime to a general curved spacetime. This theory uses a semi-classical approach; it treats spacetime as a fixed, classical background, while giving a quantum-mechanical description of the matter and energy ...
More challenging still, such a black hole has a radiated power—for the entire black hole—of 1.2 × 10 −29 watt (12 billion-billion-billionths of one milliwatt). [9] Such an infinitesimal transmitted power is to one watt as 1 / 3000 th of a drop of water (about one-quarter the volume of a typical grain of table salt) is to all the ...
To whoever is willing to improve the article, here is a link to a review article: Don N. Page, Hawking radiation and black hole thermodynamics, New Journal of Physics 7 (2005) 203.. --Lambiam Talk 18:16, 29 October 2006 (UTC) Thanks (although the link seems to be broken), I plan on improving this article sometime, only I can't say when.
