Jeff-Relf.Me <@.> writes: >What happens to your precious "potential energy" after >black holes have all evaporated away, Moroney ? You have all the emitted photons & particles radiating away from the BH location, with their center-of-mass still located at the site of the BH at the time of emission. Their CoM will be co-moving with that of the BH (conservation of momentum) so gravitational potential energy in total will continue to increase, unchanged. Even when there is no longer a BH the CoM continues along the same path, receding from the rest of the universe. These particles may or may not encounter each other, so now we would have to ask if protons, electrons, neutrinos and photons decay over (infinite) time, and if so, to what. >Entropy ratchets up, so time ticks on, relentlessly. We see the universe get larger, infinitely, less of the energy being thermodynamic free energy, yet still more energy becoming gravitational potential energy (not countering entropy as it's decreasing the energy of motion (and dark energy?)). The total gravitational energy does have a limit, essentially the energy corresponding to the escape velocity of everything with respect to everything else. Is there a process that, with infinite time, can convert this gravitational energy (and residual motion energy) to heat energy? None known at this time AFAIK.
