It doesn't make it any less stupid. "Universe" is meant to be the all encompassing entirety of existence. "Multiverse" is just redundant. Actually, no. http://www.youtube.com/watch?v=kYAdwS5MFjQ And http://www.youtube.com/watch?v=jI50HN0Kshg OR (I'm more of a fan of this one) http://www.youtube.com/watch?v=JkxieS-6WuA http://www.youtube.com/watch?v=ySBaYMESb8o Can go on all day, the point is, the term "multiverse" is not redundant, far from it actually... May I suggest you consider the idea of looking at a universe as a "plane" of existence with its own natural "rules", and compare it to a multiverse, where there might be other universes with different rules? I guess that's the tl;dr version.[/hide] You do know who Michio Kaku is, right? He's a TV personality. He's an entertainer. He's a theoretical physicist who won't shut up about science fiction, futurism, and worst of all, string theory. He's only here to make science sound cool. The term "multiverse" at its core is redundant. As I said before, universe means "everything". There can't be more than one "everything", unless you're playing "what ifs" like DC comics, Marvel comics, and string theorists love to do. Sure, Runescape is a fantasy game, sure it can indulge itself in any silly pseudoscience bullshit it wants, but it doesn't even use the idea consistently. It's said that Guthix opened portals to different planes of reality after he stole Katagorborgogath's sword. One of these "planes" was a moon inhabited with fairies. It turns out that this moon was Gielinor's, and it was known as Zanaris. That means Zanaris and Gielinor, although referred to as "seperate planes" are actually existant not only in the same UNIVERSE, but also right next to eachother.
