Is there a technical or scientific explanation behind Sams experiment?
It involves super string theory and an expanding but finite universe. The layperson’s explanation that was given on the show goes as follows: Imagine that your life is represented by a piece of string. One end of the string represents your birth, the other your death. If you tie the ends together, your life is a loop. Ball the loop and the days of your life touch each other out of sequence, thereby leaping from one point to another would move you back and forth within your own lifetime.
