hey. The way I think you use time is through the gravemetric force of a black hole. And a ship that can travel at faster then light speeds. accelerate through the worm hole to be put in a random place in the universe at a random time. OR you would be put at a random time same place. THESE ARE MY opinions if you want to add something please do so but copy it and e-mail it to me at [email protected]. Maby we can have a little discution.
