Is there a generally accepted Physics explanation of the apparent "small entropy" of the big bang vs the apparent "large entropy" of theoretical the big crunch?
Entropy is a measure of the disorder or randomness in a system. In the context of the big bang and big crunch, it refers to the amount of disorder or randomness present in the universe at different stages of its evolution.
During the big bang, entropy is thought to have been very low, as the universe was highly ordered and uniform. As the universe expanded and cooled, entropy increased, leading to the formation of stars, galaxies, and other structures. In a big crunch scenario, entropy would decrease as the universe collapses back into a highly ordered state.
Yes, entropy is thought to play a crucial role in the eventual fate of the universe. The second law of thermodynamics states that entropy always increases in a closed system, which suggests that the universe will continue to expand and become more disordered over time. This is known as the "heat death" of the universe.
No, it is unlikely that entropy can be reversed in the big crunch scenario. The collapse of the universe into a highly ordered state would require a significant decrease in entropy, which goes against the second law of thermodynamics. However, some theories suggest that a big crunch may lead to a new big bang, restarting the cycle of expansion and increasing entropy.
Entropy is closely related to the concept of time in the big bang and big crunch. As entropy increases, time moves forward and the universe becomes more disordered. In a big crunch scenario, time would seemingly reverse as the universe collapses and becomes more ordered. However, the concept of time in these scenarios is still a subject of debate among scientists.
