    No one knows what a photon looks like. Do you have any clue? I have done alot of reserch on that subjekt. It is fascinating.

    A photon is quite peculiar compared to other particles. However, the general nature of quantum mechanics is that the nature of a photon will depend on how it is prepared or measured. That is, one can't speak of what a photon "looks like" in the absence of its preparation or measurement. And it's not the case of not knowing what the photon looks like, but that the photon itself doesn't have a particular "look" in the absence of its preparation or measurement.
    A tensor equation that is valid in any coordinate system is valid in every coordinate system.
