Question
Let us assume that an object is travelling at speed of light and a flash light is kept pointed in the opposite direction to the velocity of object. Then can we see the beam of light coming out from the flash light if we stand still behind the object?
And will we be able to see anything behind us or will it be dark as we are travelling at the speed of light and it will not be able to to reach to our eye? And is my assumption correct that a man standing beside the object will see the object infinitely long?
Explanation / Answer
Ok let us assume that an object is travelling is travelling at speed of light
No, let's not do that because it violates known physics. You can't use physics to describe scenarios which violate physics.
If the object is traveling at some large fraction of the speed of light, the light from the flashlight will be Doppler-shifted
