I don't think there's really an end to anything, it's just what our human brains perceive. If one were to think in terms of what there was before "anything" come to be, then it only makes sense that this very same "stuff" exists eternally, looming infinitely to spark everything into being again.

I found it kinda funny about the inset picture of "The Dark Ages", click to enlarge for a close-up view of absolutely nothing......lol.
