Time travel is implied right from the first episode of the CW’s rendition of The Flash where a newspaper from the future is seen in the closing scene. The rest of the first season builds a fine time-travel arc that includes a nefarious time traveler from the far future, a classic grandfather paradox with a twist (sadly not examined), a do-over day for the Flash (which Harrison Wells calls “temporal reversion”), and a final episode that sees the Flash travel back to his childhood (as well as a hint that Rip Hunter himself will soon appear on the CW scene). —Michael Main
Wells: Yes, it’s possible, but problematic. Assuming you could create the conditions necessary to take that journey, that journey would then be fraught with potential pitfalls: the Novikov Principle of Self-Consistency, for example.

Joe: Wait—the what, now?

Barry: If you travel back in time to change something, then you end up being the causal factor of that event.

Cisco: Like . . . Terminator.

Joe: Ah!

Wells: Or is time plastic? Is it mutable, whereby any changes in the continuum could create an alternate timeline?

Cisco: Back to the Future.

Joe: Ah, saw that one, too.
The Flash, in his red costume, zig-zags through an empty city street, leaving a
                yellow electric bolt behind him.
