In physics, Wheeler–Feynman theory is a nonlocal, Lorentz invariant, theory of electromagnetism in which charged particles do not act on themselves, but only on other particles. As a consequence, the motion of a charged particle depends on the past and future motions of all other charged particles. This theory avoids the problem of the self-mass of a charged particle, but requires considering future motions, and so is not commonly used.
Richard Feynman, a Nobel Prize winning physicist, was a graduate student while Professor John Wheeler's taught at Princeton. Although Wheeler was less than 10 years older than Feynman, he admired Wheeler and his intellect so much that he asked him to be his thesis advisor.
