I once heard something somewhere. It was, basically, that we cannot explain what is not of our universe. Of a universe unlike ours. I don't quite agree with that. Since we can come up with things that are not logical in any way, other universes could be explained. Only difference is that here in our universe all that knowledge would have no practical value. What do we know about our own world? Everything we know comes from seeing how one acts with another. So, if we could somehow see how things act with each other in another universe, "rules" would start deriving. A new, different kind of science. Any thoughts?
