: Well, in reality B does observe A's clock running faster than his own
: when they approach each other
: and slower than his own when they move away from each other.
:
: I will give a simple example:
Don't bother.
: If A and B move towards each other at relative speed of 0.8c (80% of
: speed of light) then they see each other living faster 3 times
Well, in reality that's bullshit. Learn basic Doppler.
c+v
f' = f* --------
c
They see each other living faster 1.8 times, your arithmetic is hopeless.
