You wish to make a round trip from Earth in a spaceship, traveling at constant speed in a straight line for 6 months and then returning at the same constant speed. You wish further, on your return, to find the Earth as it will be 1000 years in the future. (a) How fast must you travel? (b) Does it matter whether or not you travel in a straight line on your journey? If, for example, you traveled in a circle for 1 year, would you still find that 1000 years had elapsed by Earth clocks when you returned?

  1. This question is among one of the core question that force einstein to think about the most general situation that would finally results general relativity by einstein. In other word that think dont matter in STR but it will matter actually and that is question mark on str. the reson for this is that str is only aproximation, in which we suppose things as inertial but actually they are not.
