Shortest Proof That SR Self Contradicts In The World Suppose SR is correct, it would then follow that the Lorentz contraction formula is correct. That formula is: L = L0 (1-v^2/c^2)1/2 Suppose that formula is true. As you can see, if v=c, then L = (L0) times zero, hence L=0. Now, by the fundamental postulate of relativity, all photons in a single inertial reference frame have the same speed, which is 299792458 meters per second. So let us discuss photons, so that we know v=c in the above formula. The question now is, how are we to interpret Length contraction. IN the case of bodies, we conclude that the bodies themselves shrink. In the case of motion through space, we have to say that the distance traveled has shrunk. So consider a photon moving though space. Suppose that in its frame, it has traveled 299792458 meters, and suppose that this value is L, according to another observer in an inertial reference frame. Thus, an observer in an inertial reference frame has to have the following relativistic calculation: 299792458 = L0 (1-1)^1/2 = 0, which is clearly contradictory. This is the shortest proof that relativity is self contradictory in the world.
