The story posits that there are multiple universes, and The Flash (Barry Allen) can travel between them by changing his "vibrational frequency". He travels to "Earth-2" where he meets the Flash from that world, a Flash he's only read about in comics books, named Jay Garrick.
Maybe writer Gardner Fox wasn't so crazy...
From NPR's science desk, a story on the possibility of multiverses.
From the article:

Does that sound confusing? Try this:
Think of the universe like a deck of cards.
"Now, if you shuffle that deck, there's just so many orderings that can happen," Greene says. "If you shuffle that deck enough times, the orders will have to repeat. Similarly, with an infinite universe and only a finite number of complexions of matter, the way in which matter arranges itself has to repeat."
|I'm just saying.|
