It assumes life is subject to the second law of thermodynamics, which it is.
Avoiding heat death requires a renewable source of negentropy, to bypass the second law. Some sort of perpetual motion machine that you can pump energy out of. E.g. if you could extract work out of the expansion of the universe fast enough to build expansion-work-extractors faster than they decay, and expansion continues indefinitely, then you can avoid heat death.
- douglaswlance 5y agoLife itself is a renewable, exponentially growing form of negative entropy. We can't predict what life will be doing in 100 years. What will it look like in 100,000,000 years of exponential growth?
- Strilanc 5y agoYou should read the wikipedia article "Entropy and Life" [1]. Life is not a growing form of negentropy. This is why living things have to eat. 1: https://en.wikipedia.org/wiki/Entropy_and_life https://en.wikipedia.org/wiki/Entropy_and_life
