Closed Timelike Curves

  1. Jan 14, 2015 #1
    In theory, is time travel to the past possible by traveling completely around the loop of the CTC (where it would seem future links with its own past) or is a wormhole the only way to time travel by way of short cutting the CTC.

    I'm not aware of any formal physics definition for a "wormhole" and have always thought of a CTC being the same thing as a wormhole.

    So what's a wormhole?

    Google for "wormhole metric".
