[QUOTE="keeper blue, post: 6824657, member: 730986"] Body 1 travels 48 light years from point A to point B at 82% of light speed. Body 2 leaves point A 33 years after Body 1 and travels the 48 light years to point B at 99.99995% of light speed. What I think I know: [LIST] [*]Body 1 takes 58 years to reach point B according to an earth observer. [*]Body 1 takes 33 years to reach point B according to an on board observer. [*]Body 2 takes 48 years to reach point B according to an earth observer. [*]Body 2 takes 14 days to reach point B according to an on board observer. [/LIST] What I do not know and I hope someone can tell me: [LIST=1] [*]If Body 2 sends a message to Body 1 on their departure date [LIST=1] [*]When will Body 1 receive it (on board elapsed time) [/LIST] [*]According to Body 1, how much time will elapse between their arrival at point B and the arrival of Body 2? [/LIST] This is research for a SF novel but one which adheres to the known laws of physics, so I need to get it right and really appreciate your help in doing so. Mike [/QUOTE]
