  I posted an answer to a similar question here: ////neptuniumn17-zone//2017/11/06/are-there-other-universes/ – that question asked if there were other universes, and I ended up going with a guarded “maybe, but it’s hard to know.” I think that if there *are* infinite other universes, then it stands to reason there might be similar timelines, ones like us but a bit further forward or back in time from us. After all, if there are infinite universes then there are infinite possibilities, right?
  If any of you ever figure out the truth of this question (and maybe how to travel there) please let me know! 😉
