That some violation of energy-(if-we-don’t-count-energy-from-large-scale-spacetime-shape-stuff) (not counting energy from large-scale spacetime shape stuff may be sensible, because AIUI you can’t really obtain it as just a sum of local quantities, and like, it depends on boundary conditions or something) occurs doesn’t imply it is possible to exploit to obtain more energy. Does this violation even ever result in more usable energy rather than less? Like, red-shifting photons reduces their energy… I suppose if we wanted to do the opposite, it would be making the contraction of space result in photons being blue-shifted, but uh… Well, that would result in things getting closer together, and unlike expansion, that seems to run into a limit at some point? I don’t think the laws of physics as they currently are, are sufficient to support an eternity of life (or civilization). For there to be hope of that, it must be hope of something or someone outside of the laws of physics we inhabit (or are well-approximated as inhabiting). A new heaven and a new earth.
