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.
