I think that's a slightly incorrect TL;DR. Here's an updated version based on my reading: TL;DR: a heat death (Big Freeze) due to eternal acceleration was the previously favored candidate for the fate of the universe; but there's now evidence that dark energy varies, so acceleration may not be eternal; we may still get a Big Freeze (if it stop varying soon) or we may get a Big Crunch (if it keeps going far enough in the direction it has been going) or we may get a Big Rip (if it starts going in the opposite direction that it has been going) |
