I personally believe that as a universe is written or created it comes into existence, and that time is fluid and non-linear and so all universes are always happening in the past, future and present all the same. This is why I have a hard time thinking my “kinself” is any different from me now, because I exist in the past, present and future. AUs and stuff are the same, in that they become a separate world with existing framework, just different. Just offering someone else’s take on it. :3
Great perspective, anon! Very interesting.
