Standard calculations suggest that the entropy of our universe is dominated by black holes, whose entropy is of order their area in Planck units, although they comprise only a tiny fraction of its total energy. Statistical entropy is the logarithm of the number of microstates consistent with the...

One of the rules about entropy is that it cannot decrease. What is the effect of this on our everyday lives? To better understand let’s zoom in on the molecular basis of matter. Part one: a simple definition Part two: birth of the Second Law Part three: the way the universe will...
Scitation is the online home of leading journals and conference proceedings from AIP Publishing and AIP Member Societies L Lederman,VV Raman - 《Physics Teacher》 被引量: 112发表: 1993年 What is the entropy of the universe? Standard calculations suggest that the entropy of our universe is domina...
However, this would result in the "Big Freeze," with energy being so spread out and the universe reaching a state of maximum entropy, meaning that no work can be done and no energy can be transferred because everywhere would have exactly the same, cold temperature. The big caveat to all ...
To superstring theories, dealing with the unification of the four known forces during the evolution of the early Universe, and black holes, the end product of gravitational collapse, have been attributed rather peculiar thermodynamic properties such as lack of concavity, with the consequence of ...
probability of a new particle being of some type “A” is proportional to the number of states that “A” can be in, which is exactly how you go about maximizing entropy. So, you can write off the selection of new particles as just another attempt by the universe to increase entropy. ...
Entropy and Heat Death of the Universe Some scientists predict the entropy of the universe will increase to the point where the randomness creates a system incapable of useful work. When only thermal energy remains, the universe would be said to have died of heat death. ...
Q: What is the entropy of nothing? Q: How can quantum computers break encryption? Q: How does quantum computing work? Q: What causes buoyancy? My bad: If atoms are mostly made up of empty space, why do things feel solid? Q: How many mathematicians/physicists does it take to screw in...
not decrease. Black holes seemed to reduce the entropy of the universe, because when the cup falls inside it is lost forever. Wheeler didn't like the whole thing. He turned the problem over to Jacob Bekenstein, one of his students at Princeton. To solve the dilemma, he proposed ageneraliz...
