I never was comfortable with the idea of an infinite number of possible universes resulting from time travel to the past.
"I never was comfortable with the idea of an infinite number of possible universes resulting from time travel to the past."
The number of universes ceases to be infinite once one has been "fixed" into place. So, if time travel is at all possible, know that you're destined to do it, if an older version of you ever pops in to say "hi." And nobody will be erased from existence due to your having done it. I still wonder why this would be the case, if there is no deity, though.
