On a level that makes sense. But then I wondered, "wound down" from what? I think then that the cosmos would have had to start out in a wound down state. If it was ever in a non-wound down state, then I don't think it would not be able to wind down.

I don't know, but I can't imagine it any other way. It would seem illogical for one to be infinite but the other to be finite. Having an infinite space with fine time makes one wonder, what happens to the unused space? By contrast, a finite space and infinite time would lead to heat death, I think.
