CERN theorists seem baffled, but it’s no surprise that standard physics predicts supraluminal (FtL) neutrinos to slow down via Cherenkov radiation analogous to FtL charged particles, although Cohen & Glashow call it bremstrahlung of electron-positron pairs. Cherenkov radiation is best depicted by analogy with the sonic boom of a supersonic projectile – a sonic boom in the electromagnetic field from a supersonic particle. Likewise, a FtL neutrino would generate a sonic boom in the gravitational field and slow down to ‘c’ (not lower as suggested).
Another argument (neutrino-reaction) is that light is slowed below ‘c’ due to transient electron-positron pairs – zeropoint vacuum fields – but neutrinos are not slowed. This forgets that the field energy has an equivalent gravitating mass (E/c2), which decreases ‘c’ below cvaccuum – FtL neutrinos slowed to ‘c’ by Cherenkov-type emission.
It seems physicists need reminding that the powerful Einstein-Hilbert gravitational field equation includes source terms from field-energy, both gravitational and electromagnetic. Depicting fields as particles – whether gravitons or photons – can readily mislead.
