speed of C = speed of A ie:C&A are maintaining the same distance between themselves....B just happen to be between them
after rethinking my answer, i further propose a new problem...B is s stationary object....A moves away at the speed of light, C moves away in the opposite direction at the speed of light....now what is the relationship between objects.
if fact, if the "big Bang" theory is correct....there is matter traveling in opposite directions.....therefore, if you are going 1/2 the speed of light north, and I am going 1/2 the speed of light south....we could never see each other. ever
No, I was trying to describe:
< < < A < < < - - - B - - - > > > C > > >
A and C are moving in opposite directions, each moving away from B at the speed of light. It has been a few decades since I had quantum mechanics.
