>>13655564if multiverse is right, and there is a practically infinity number of universes, the particle in at least one of those universes will suffer a small random dipt in entropy that will make particle spontaneously organize in a structure that is indistinguishable from your body, complete with you memories and personality(or at least in the memories and personality, with the body and it's works being an equivalent for that, assuming that universe has different set of particles/physical law) or some being in that other universe will be born with your exact memories and personality
if the memories and personality are the ones that you have right before your death, you will have been functionally isekaied
therefore, if multiverse is true than isekai is inevitable
you only need to wait
