Closed Timelike Curves

    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".
