It's a speedster thing. I mean, we all know how time slows down the faster you go, so technically, the folks who flew on the space shuttle are maybe a second or two younger than the rest of us, relativistically. This is more, well, you go as fast as you can and take a blind leap. It's really hard to control when you end up, or where. It could be a decade or two, or a thousand years.

[Bart doesn't want to go into how they're pretty sure that the Speed Force helps with pulling someone where it thinks they need to be. It's...spiritual, and that doesn't always go over well. Most people don't like the idea of fate or destiny.]

I've never done it. I've got too much holding me back.
