## Main Question or Discussion Point

If someone would be so kind as to show me the math of why a reference frame for a photon wouldn't work?

"Problem #1: In the frame of reference of some photon in that beam, what is the velocity of some other photon in the beam? We have a slight problem here with the second postulate of special relativity, which says that the local speed of light is the exact same value, c, in all reference frames.

Problem #2: Another aspect of special relativity is that one can transform from any one inertial frame to another using the Poincare transform. Try going to/from the photon frame of reference using this transformation. There will be a slight problem with dividing by zero / multiplying by infinity here."

This was quoted from the user D H in a thread I came across. I would like to see the math involed with is, along with any other equations that back up why photons have a frame of reference wouldn't make sense.

Thank you
