Relativity, time, and aging
With Einstein's Theory of Relativity, would time travel be possible?
The closer you get to the speed of light, time supposedly slows down. I r
remember that an experiment was set up with two synchronized atomic
clocks. One was sent up in a satellite, and the other stayed on Earth.
When the orbiting clock came back down, it was slower than the other one.
How could we achieve those results with aging?
It works exactly the same way. The person who makes a fast trip to
Arcturus and back will find that the civilization that he or she left will have
totally died out (or progressed, or whatever). Unfortunately it only
works in one direction. If you could take a trip backward in time, you
would probably have to return to a different universe.
Find yourself a copy of "Faster Than Light" by Nick Herbert. It is very good,
short and fun to read.
