Time Travel Creation

Time travel is the process of leaving the timestream at a given point, traversing through the timeless realm of Limbo for a timeless interval, and re-entering timestream at another point, not having physically aged in transit. Since there are alternate futures, it is not always possible to travel to the same one. Since traveling into the past always affects reality in at least a minute way, one can never physically travel to one's true past, which is by definition the past in its original state, uncomplicated by extra temporal factors.

Limbo is a dimension that is unique in that it exists outside the timestream and thus possesses no time. Reality in Limbo is comprised of a single, ever-changing moment in which everything that ever was, is, and could be coexist. Human  beings within Limbo might imagine that time passes there, since they are conditioned to think in such a way, but they cannot age or die there.
