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.

When I start seeing you with a goatee I'm going to worry.
(Note to self: Don't wear a red shirt that day.)
I love to travel to a PU and screw up another me's life. But it's a PITA when one of them comes here and messes everything up.
