John, we are all doing this now. We are moving forward through time
while moving through space. Special relativity theory states that our
rate of moving through space affects our rate of moving through time,
essentially. As one travels faster and faster, one travels less quickly
through time. The traveler's clock appears slow to outside observers --
"time dilation". With enough speed and a sufficiently long trip, one
could end up younger than one's children. However, that clock does not
run backwards; it is impossible to see one's parents growing up. The
cost of this slowed pace of traveling forward in time is the energy
required to reach that speed. This is especially noticable as one
approaches the speed of light in free space.
Possibilities become broader with the general relativity theory,
however, due to the warping of space. Modern theories that go beyond
Einstein's theories have included such fascinating possiblities as "worm
holes" -- short cuts through space and time, as it were, with the
possibility of moving backwards in time. Unlike the special theory of
relativity and the general theory of relativity, these have not been
proven experimentially, however.
