I race with a beam of light, start point A n finish point B.You cannot travel at the speed of light.
Both light beam n my velocity is same = speed of light.
No matter how close you come to the speed of light (as measured from your point of departure,as well as that of the beam of light) the beam of light ,if you were able to measure its speed would still be c .
The only difference would be its frequency .
