  1. Electrodynamics paradox

    by , 06-11-2011 at 06:49 PM
    This is a question about general relativity and classical electrodynamics. Consider an electron freely falling under the influence of gravity. In it's own frame of reference it feels no acceleration and should not radiate (principle of equivalence). But in the frame of the body exerting the gravitational force it is accelerating, so it should radiate. How can it radiate in one frame of reference and not in another?
