…Then do our future descendants have any constraints in terms of... Because earlier we were mentioning, as a catastrophe, we found out about the cosmological constant because it limits our cosmic horizon and thus limits the free energy that our descendants would have access to. But if you can just make entire universes... Then this is a matter of extreme interest, I would say, to us. It won't be relevant for tens of billions of years, probably, because that's the timescale on which the cosmological constant operates. But if the cosmological constant is truly constant, and we've only known about it for 25 years, and there are astronomical observations that seem to be in tension with that, but if it is truly constant, then there is a finite amount of free energy in our universe. If it's not constant, if we can manipulate it, or even if it naturally decays on its own, then there is the possibility of an unbounded amount of free energy in our future, and we would avoid a heat death scenario. The situation you mentioned earlier, where somebody seeded our universe, they've created a bunch of energy. That's related to them having something equivalent to a positive cosmological constant in there.…
