Is there entropy in a black hole
WitrynaIn a variety of quantum gravity treatments, string theory, LQG and doubly-special relativity, models based on non-commutative geometry, there exists a common topic: … WitrynaHowever, there exist classical solutions to the Einstein equations that allow values of the entropy larger than those allowed by an area law (radius squared), hence in principle larger than those of a black hole. ... Black hole entropy is deeply puzzling – it says that the logarithm of the number of states of a black hole is proportional to ...
Is there entropy in a black hole
Did you know?
WitrynaAnswer (1 of 4): Brief answer: Thermodynamic entropy will increase in ordinary black holes, but only decrease in central black holes in the center of galaxies. That is … WitrynaThe quest to understand the quantum aspects of gravity has a long history. Namely, since Einstein introduced the theory of general relativity (GR) [] and the first black …
Witrynatoday, most of the entropy is converted into gravitational en-tropy in the form of black holes. The central result is that there is no entropic limit on how many cycles there could have been in our past or will be in our future. Slow contraction and non-singular bounces Bouncing mod-els based on slow contraction and non-singular bounces require WitrynaI derive the Bekenstein-Hawking formula for the entropy of a Black Hole. In my opinion my derivation is just as rigorous as one based on Quantum Field Theory...
Witryna18 maj 2024 · Now, three independent studies have shown that string theory can offer a microscopic accounting of entropy for certain theoretical black holes [ 4 – 6 ]. The … WitrynaEntropy of black holes and cosmic horizons are considered. The contribution to the gravitational entropy according to the Weyl curvature hypothesis is discussed. The …

WitrynaThe initial entropy of the system (black hole plus cosmological horizon) is S = Sm+Ac/4. Here, Sm is the entropy of the matter (black hole) inside the cosmological horizon and Ac is the area of cosmological horizon in the presence of black hole. At the end of process of gedenken experiment for constructing D-bound when there is no black hole github 5city hackWitrynaThe entropy of a black hole is given by the area A of its event horizon according to the formula S = k A 4 l P where k is Boltzmann's constant and l P is the Planck length.
