There's Time Travel and there's Dimension Hopping. Both of these are fairtly straightforward, once you get the hang of it. But visiting Parallel Universes is a bit trickier. You're there, and you're there also. But one of the you's isn't you, cuz he/she was subject to a different set of events following a spin-off at a Key Historical Juncture.
That's how Parallel Universes come into existence, you know - at critical points in History. In theory, there are an infinite number of PU's. But when you're in one, with another you, it's dreadfully diffucult to make a jump to yet another PU. And you really don't want to get too far away from your Home Reality.
