@ Crazy Anglican:
"Show me where NASA refutes multiple universes theory and you might have something."
I can't quote NASA outright refuting multiple universes, but I can quote NASA saying that from a scientific standpoint the question is essentially pointless:
"There is no way to observe any universe other than our own. This is not a practical issue (like there not being good enough telescopes), but rather a fundamental theoretical issue. By definition, our universe is self-contained. No other universe can affect anything in our universe, so we cannot gather evidence about its existence.
"Applying Einstein's laws of general relativity, it is possible to come up with solutions that connect one universe to another via a spinning black hole. However even if we were to observe such a thing, it would still not tell us if there was another universe on the other side or if the other side was part of our own universe.
"So, from a scientific standpoint the question is moot, but from a philosophical standpoint, it is fascinating."
