Let's say that scientists somehow discover that the universe is infinite. In particular, they say that after the big bang, the universe expanded everywhere. In that case, if the universe is infinite and it takes up all space, does that mean that the multiverse isn't real and that our infinite universe is all there is? Or, could the multiverse still be true? 

**Could there be an infinite number of universes, all of which are infinite but are separated from each other?**
