About the clocks part, that was one of the first real experimental time-dilation
tests conducted physically, with a real clock. A group of scientists boarded
a plane that went from (I think, London to New York) with a Maser/Laser Clock,
which, at the time, was ridiculously accurate, and found that people on that
flight were actually trillionths of a second younger than those who were not
on the flight (excluding others who happened to be flying elsewhere, I suppose.)
As far as this post, the only Time Travel theory I know of is moving into
the future, it basically consists of a giant gravity hole somewhere in space,
and the distance around the circumference of the circle is actually a lesser
distance than going into the well, so, if you were travelling at the speed of
light, (not 88 MPH) you could see yourself some out of the well, of course,
it would be a ridiculously short time later.
