pln2bz writes: Scientists are spinning the recent observation of electrons' inherent rotational properties in the absence of a magnetic field as a breakthrough towards the eventual creation of a quantum computer. That may be the case, but it's worth noting also the works of Wal Thornhill and Ralph Sansbury, who have suggested a theory that can explain gravity, magnetism and light on the basis of an internal structure for electrons, called subtrons. Their theory appears to predict these latest observations: "Simply stated, all subatomic particles, including the electron, are resonant systems of orbiting smaller electric charges of opposite polarity that sum to the charge on that particle. These smaller electric charges he calls 'subtrons.'
... In this model, the electron cannot be treated like a fundamental, point-like particle. It must have structure to have angular momentum and a preferred magnetic orientation, known vaguely as 'spin.' There must be orbital motion of subtrons within the electron to generate a magnetic dipole. The transfer of energy between the subtrons in their orbits within the classical electron radius must be resonant and near instantaneous for the electron to be a stable particle. The same argument applies to the proton, the neutron, and, as we shall see — the neutrino." If Thornhill and Sansbury are right, then the speed of subtrons would be on the order of 2.5 million light-years per second — so fast, in fact, that they could travel to the other side of Andromeda within just one second. Not only might this elegantly explain why many quantum effects appear to us as instantaneous, but their combined works also clarify some prior anti-gravity claims.
