OPERA review serves up a feast for physics geeks

c Can't Be Measured Using Light "in a vacuum"

The OPERA results and Einstein's relativity can both be correct as long as the definition of "c" is re-evaluated. When light travels through air or water it travels slower than "c". So to measure "c", the speed of light was measured "in a vacuum". Why, until now, hasn't anyone said "Wait a minute, according to quantum mechanics, there's no such thing as a vacuum, so that measurement must really be slower than 'c'"?

In a vacuum, a quantum soup of particles is constantly coming into and out of existance. Light interacts with these particles. Neutrinos interact with matter alot less, so the speed of nutrinos in the earth's crust could actually be closer to "c" (but still a bit slower). The speed of neutrinos in a vacuum would begin to approach the real value of "c".

In addition to these temporary particles, a vacuum may also contain a Higgs field, which could be another factor in slowing the speed of light below the real value of "c".
