> This solves all paradoxes with time travel as you never change the past, but rather, you are creating/finding forks of reality that appear backwards/forwards in time. You would be breaking conservation of mass/energy, though. Either you restate 'conservation' such that it applies across all universes instead of just within one (and you are moving energy/mass , in which case the number of timelines has to be fixed (which leaves open the possibility of paradoxes), or you're still violating conservation by creating entire universes every time you fork the timeline. There are ways to get it all to work out, but they are all pretty weird and unintuitive. The first is that paradoxes are simply not permitted (or more accurately, can't be observed) and that the universe hides attempts to create them the same way it hides information that would violate the uncertainty principle. The other main way you can resolve it is by asserting that while there are an infinity of parallel universes, and more are being spawned all the time, just as many are merging, keeping the number of universes at the same infinite number. Time travel is then permitted to spawn a new universe as long as the books remain balanced. Of course, the easiest way to balance things is for any changes to not matter enough to prevent timelines from merging again.
