Main Question or Discussion Point
i wish to know if matter can be transferred from one universe to other universe? does our universe have valve like thing to let the matter in or out of the system?
What he said, but I sometimes like to speculate that there are many Universes, since the beginning of time we've been wrong about much of the Universe, and when I like to think about it, I say why not, it could be a possibility (Don't count on my words because there is no proof for this), we used to think there was just the solar system, but nope there's billions which is probably an understatement! Also then we discovered that we live in an island of stars which is our galaxy, that was only 1 of billions! So I like to think, why can't there be more than 1 universe or even billions, where they can transfer energy from one universe to the other!"Other universe" is highly speculative and is not supported by ANY evidence so your question has no answer.
There are two ways of defining "universe". One is anything that we can measure or affect. So, by that definition, the universe is a closed system.i wish to know if matter can be transferred from one universe to other universe? does our universe have valve like thing to let the matter in or out of the system?
