  • Maxwell's Equations Do Not Predict That the Speed of Light Is Constant

    The derivation says nothing about whether or not the speed of light relative to an observer varies with the speed of that observer. Maxwell believed that it did vary:

    John Norton: "[Maxwell's] theory allows light to slow and be frozen in the frame of reference of a sufficiently rapidly moving observer." http://www.pitt.edu/~jdnorton/papers/Chasing.pdf

    The speed of light relative to an observer OBVIOUSLY varies with the speed of the observer. Consider Doppler effect (moving observer):

    The speed of the light pulses relative to the stationary observer is

    c = df

    where d is the distance between subsequent pulses and f is the frequency at the stationary observer. The speed of the pulses relative to the moving observer is

    c' = df' = c+v

    where f' = (c+v)/d is the frequency at the moving observer.

    What isn’t understood even by anti relativists like Norton or Pentcho is that we *can*
    see light “frozen”. It is called the atom. Each atom is a “frozen “ set of standing waves
    where the the atom doesn’t move relative to us the observer...but rather the source is moving
    away from us and the atom at c. Specific wavelengths of these waves overlap at a single point in space forming a collection of standing or frozen waves called...
    ...the atom.
