Taking from the infinite. With my original question I didn't think too hard on the point that if one did take a drop of water from an infinite ocean they would have no place to take it. And if I created infinite land next to an infinite ocean that might create even more questions.
I was largely thinking in terms of the movie, "Dr. Strange" in which the Ancient One keeps her youth by stealing energy from the dark dimension which I was led to believe is an infinite world as perhaps our universe maybe as well. So basically 2 or more infinite universes at least in the fiction exists. The Ancient One had an ethical dilemma over her theft from the dark dimension even though in theory nothing is lost, but I wasn't sure. Many physicists believe there could be many worlds split into more worlds whenever a paradox needs to be resolved so Schroder's Cat can actually be both alive and dead, but in different worlds.
