Hello All,
I'm trying to wrap my head around SR and I have a couple questions: If two space travelers (A) and (C) take off from a Planet (B) in opposite directions and each travels just over 1/2c, do they vanish from each others' view? I don't see why they wouldn't but
If yes, doesn't that violate SR which nothing can travel at v > c? Since they don't observe each other is that avoided?
Also does that mean that no information can ever travel from (A) to (C)? If yes, couldn't (B) just act as a medium of communication which is moving at < c in relation to both (A) and (C).
Also, let's say (A) and (C) turn around and travel back toward each other with a combined v > c, what would this look like to each space traveler?
Thanks for your time,
Rich
