Stochastic ElectrodynamicsStochastic electrodynamics (SED) is a theory derived from quantum mechanics which attempts to explain numerous phenomena including inertia, gravity and the radiation paradox of the Bohr model of the atom in terms of a fluctuating electromagnetic field associated with zero-point energy. This field consists of a superposition of random waves of all frequencies and phases in all directions, with a power spectrum proportional to the cube of frequency, up to a very high frequency cutoff on the order of Planck time (presumed to be due to quark interactions). The zero-point field's existence is theoretically derived from the fact that in quantum mechanics the lowest-energy state of a harmonic oscillator (such as a single mode of an electomagnetic field in vacuum) is not exactly zero. This is assumed to be merely an abstract mathematical result in quantum mechanics, but stochastic electodynamics starts by assuming that the implied field is real, and treats it as a random (stochastic) classical field acting on classical point particles. The frequency-cubed form of the power spectrum is derived from the requirement that the power spectrum be invariant under Lorentz transformation. Phenomena explained by stochastic electrodynamics Inertia Inertia is predicted by stochastic electrodynamics as an electomagnetic drag force on accelerating particles, produced by the zero-point field. Gravity Gravity is predicted by stochastic electrodynamics as an electomagnetic induced dipole shielding effect similar in nature to the Van der Waals force. The commonality of mechaisms of inertia and gravity provides an elegant explanation for the equality of gravitational and inertial mass, which is assumed but not derived in general relativity. This also allows the Planck constant to be correctly calculated from the gravitational constant, or vice versa.
