Nobody is creating snapshots, the past is lost, but in a sense it is still entirely, umm, present (forgive the pun). It is apparently not true that there is more than one past that could have evolved into the present. This has bothered me a lot and I don’t entirely understand in this moment why that is, but I’ve looked into it several times and every time eventually assured myself that it was so. Though I haven’t accounted for the idea that spaces that were once causally bound to each other can possibly become causally unbound… oh well, down the rabbit hole again.
Time is a physical entity that can be warped, but nobody is creating snaphsots of reality to travel back to and future is entirely a human concept.
Or, analogy to a river (although flawed): you can’t create a loop and expect it to still flow. But circumstances can make it flow slower or faster.
