Light Tag

    A quick question, lets just say that my friend and I became photons, and were emitted from a light source in the same direction 1 second apart. My photon friend would never catch up to me, right? Am I correct to say that I wouldn't even be able to tell that he was following me since his information would never catch up to me?

    Before you get too much further, you must live with the fact that photons cannot have a frame of reference. It is meaningless to ask what a photon experiences, even in principle.

    This may not seem relevant, but as this question continues, you will surely find this post being referred to.

    That would be true in flat spacetime but not necessarily true in certain curved spacetimes.
