Heat Death

Postby 905373636 » Fri Feb 28, 2020 12:23 pm

What does the eventual heat death of the universe say about its entropy and enthalpy relationship? Is all of the energy in the universe in its potential energy form?

The idea of the universe's eventual heat death suggests that the universe will eventually evolve to a state of no thermodynamic free energy. Therefore, it would be unable to sustain processes that increase entropy. Once we reach this maximum entropy, no more work can be extracted from the universe.

There are some cool videos on Youtube that talk about this.

One implication of the heat death of the universe that I've always wondered about is what it implies about the universe's time frame and origins. If the universe has always existed, then maximum entropy would have already been achieved and no more work could be achieved by the universe. But we have not reached the heat death of the universe, so surely, the universe came into existence at some point. The fact that we haven't already reached the heat death of the universe, by proving that the universe has not "always existed", seems that the universe was created by something bigger than us. Curious to hear your thoughts on this.
