Hi guys, I am sure this little problem has been aired before. Topic The postulate that 'c' is invariant from all frames of reference and the outcome of having a velocity of 'c' means contraction of space to zero. This would indicate that from a photons perspective space has contracted to zero thus the photons 'speed" is zero or instantaneous, and yet from a relatively stationary perspective the photon has a speed of 'c'. two frames of reference - the photons - instantaneous - zero space. the stationary observer - 'c' - 4 dimensional space. Firstly if the above is correct I DO NOT not see this as a contradiction or paradox of special relativity. If anything I see it as a strength and further validates the invariance of 'c' postulate. However, this pseudo paradox, seems to complicate things a little. yes? So I ask is 300,000 kps in a vacuum a measurement for the instantaneous? Could this figure 300,000 kps be a figure that could be extrapolated to a figure for time dillation experienced by the photon? If we work out the lorenze trandformation inversely from a position of 'c' = zero space would we arrive at 4 dimensional space?
