Hello, recently I saw a poster with a clip from a magazine that had this situation and I was wondering if this is a completely impossible situation? Wouldn't you have to go several times the speed of light ?!
Suppose you wish to visit the red giant star Betelgeuse, which is 430 light years away, and that you want your rocket to move so fast that you age only 20 years during the round trip. How fast must the rocket travel relative to earth?
