WebAn important black hole observable is the Bekenstein-Hawking (BH) entropy, which is proportional to the area of the event horizon, SBH = Ah / (4 G ). For the 3-brane solution (3.1), the horizon is located at r = r0. For r0 > 0 the 3-brane carries some excess energy E above its extremal value, and the BH entropy is also non-vanishing.

WebSep 1, 2024 · In the next section, we obtain the analytical Hawking temperature for general velocity profiles z ± 1 ∕ n (sonic) and τ ± 1 ∕ n (optical). Two formulas for sonic analogs derived in Ref. [20] are included as particular cases, including the Schwarzschild spacetime, but the rest are new analytical results from this work. We also develop an equation for a …
The second law of thermodynamics requires that black holes have entropy. If black holes carried no entropy, it would be possible to violate the second law by throwing mass into the black hole. The increase of the entropy of the black hole more than compensates for the decrease of the entropy carried by the object that was swallowed. In 1972, Jacob Bekenstein conjectured that black holes should have an entropy, where by the sa… fish market highway 280 menuWebThe value of Tmax ∼ 1032 K −1/2 is exorbitantly large to be of any use, or so it seemed at least for a long time.
