Heat death was never the only option in GR. The field equations always allowed for a big crunch or a big rip.

- fpoling 2y agoYes, but that implies that in GR entropy or at least the value based on the classical definition can decrease. So apparent increase in complexity can be attributed to gravity.
- gsf_emergency_2 2y agoSean Carroll today's go-to person for GR has been working at popularizing these ideas (for more than 10 years(!)) https://arxiv.org/abs/1405.6903 https://arxiv.org/abs/1405.6903 >For example, our universe lacked complex structures at the Big Bang and will also lack them after black holes evaporate and particles are dispersed.
