I read an article a few days ago about a way to detect them indirectly, but it only works if they act in a very specific manner.

Michael Crichton's book Timeline used the multiverse concept. He deals with some of the 'what ifs' in it, but he kinda makes a little of it up too. But it's all based on solid physics.

Other universes could exist, but time and space are a property of the universe/universes itself/themselves, so whatever is between them is undefinable in our terms, so in effect, if there are other universes, they are infinitely separated in space and time. The question arises; "If there is more than one universe, with each one continually expanding(this is dependent on the Hubble constant but that aside), will they not eventually meet at some point?". But again, this question is pointless. If you were to suppose that you had more than one universe and that they were to expand until they met, you would have to assume that they had "positions" in the "void". But as position etc . is a property of the universe, you cannot have a way of telling "where" one universe is in relation to another. So again, the universes are infinitely separated in space and time. Still though, I would mind a look at that article Sol mentioned. As for the question of what we'd call our universe if other universes were discovered, well, I think thats a bit irrelevant. It's only a name after all.

Also, if you had more than one universe, who's to say that another universe's time and space parameters would be the same as our own? They could be completely different. Actually, the more I think about the existance of other universes, the more potential problems I see. For example, what size would another universe be in comparison to our own, and how could one compare them? If the other universe had different space parameters... I'm getting a headache.

Don't bother thinking of them... Camparison is impossible, because they'll have different rules. In fact, since they are outside all we know, we can only imagine what they are like.

Actually, the theoretically infinite universes that make up the multiverse are not separated by space and time. In space/time coordinates, they may actually be colocated, or "superimposed" on one another. The problem is that they are still utterly separate.
What separates them? Well, it isn't space and time, so perhaps its yet another one of those incomprehensible dimensions the scientists are always touting. Since I am not aware that this subject has been directly addressed, I propose that we call this "separating dimension" be called unspace/time.
