Is There A Maximum Possible Photon Energy?

  1. Nov 11, 2012 #1
    Ok, so I just had a thought.
    A planck length is 1.63e-35m
    Would that mean that the smallest possible wavelenth of light is 1.63e-35m?
    Giving a frequency of 1.84e+43 Hz, and, of course, an energy of 3e8 J.

    As far as we know right now, there is no minimum lenght. This means that according to the present theories space is not quantized and so there is no upper limit to a photon energy (and no lower limit to its wavelenght).

    The planck energy (apart from small prefactors, your result) is a region where our current models in physic cannot describe processes any more. It is not an upper limit on physics itself, it is just an upper limit on our understanding of the universe.
