Are there any experiments that show how light is treated as a frames velocity is changed (not the light source, rather the "eye".) For example if a huge clock that is counting down from 10 is 10 light seconds away before I accelerate (at t=0) to a velocity where my length contraction is *.5 (I think that is gamma = 2?) How long will it be before I see the clock reach 0? If I had not accelerated it would have taken 10 seconds. (As a side note the large clock has counted down to 0 simultaneously with my t=0, just the distance delays the signal 10s in the original rest frame.) Once I have accelerated would it still take 10 seconds to travel to me or since there is length contraction would it only take 5 seconds now? or perhaps something else?
