Slow time at high speed

2/28/01

Sometime in the far distant future a spaceship may leave the earth bound for a nearly galaxy – perhaps the Andromeda Galaxy, two million light years away. The ship will be far more advanced than any we know today, so advanced that it will be able to travel at a speed very close to the speed of light. At such speeds according to the theory of relativity, time appears to slow down for the ship and its occupants. The trip will require only 28yrs earth time to reach Andromeda, and another 28yrs to return. An astronaut on board will age by 56yrs during his journey but he will not recognize the earth, he’ll return to. For during his 56yrs in space, his home, the earth will have become four million years older.
