Quite true. However, most people tend to call the universe we live in the "universe" and everything else the "multiverse."

If we entertain the current hypothesis that our universe is expanding then it is also likely that other universes are in a state of expansion or contraction. I don't think light could exist in a static universe. If all universes are in a state of flux then perhaps everything is in a similar state. If we say that everything is either expanding or contracting then we can assume that everything has a border. If we are able to go in any direction and eventually arrive at that border I believe that nothing will be on the other side. Nothing must therefor be greater than everything. kj

Why must something that is expanding or contracting necessarily have a boundary?
