WebAug 31, 2015 · 2. Black holes and the area theorem. In terms of our traffic analogy, a black hole is a one-way street . The simplest black hole is a spherical one-way street, sitting at the origin. It was discovered by German physicist Karl Schwarzschild, in 1915, while he was serving on the Russian front. Webdynamics. Famously, we now interpret M as the black hole’s total internal energy U, the quantity S A 4 as the Bekenstein-Hawking entropy of the black hole, and T 2ˇ as its Hawking temperature. Thus black holes obey the second law of thermodynamics (dS 0), and the equation above looks a lot like the rst law of thermodynamics, with and in-

Abstract Black holes have often provided profound insights into the nature of gravity WebMotivation The thermodynamics of black holes suggests certain relationships between the entropy of black holes and their geometry. Specifically, the Bekenstein–Hawking area formula conjectures that the entropy of a black hole is proportional to its surface area: S BH = k B A 4 ℓ P 2 {\displaystyle S_{\text{BH}}={\frac {k_{\text{B}}A}{4\ell _{\text{P}}^{2}}}} … WebMay 28, 2024 · Black Hole Paradoxes Reveal a Fundamental Link Between Energy and Order.
