Given a massless particle (rest mass = 0), other than a photon or
graviton, what would be the relativistic explanation for why it can
travel faster than c? What aspect of electromagnetic radiation make
its speed of propagation in free space an upper bound on speed? I
suppose the answer lies with the derivation of the sqrt(1-v2/c2) term
in SR, but I could use some insight from those of you that have a
strong understanding of relativity and its derivation.
Thanks
It hasnt to do with relativity. Consider Nimtz double prism experiment.
Photons can move through
the tatal reflection gap between two prisms with superluminal velocities (in
the case of vacuum instantly).
The tunnelflux explaining this must be formed analog to the pointing vector
but the fields involved
is an overlay of the "refracted" and the "reflected" wave in the gap.
Nimtz interpretation therefore is right.
This tunnel fluxes are also needed in thin metal layers in order to get
energy consevation at the boundaries.
Besides them one needs also the concept of finte vacuum layers between other
material layers.
This finite vacuum layers seem to make renormalization exact solvable. And
they seem to be the ether
in the heads of physicists.
So this all is makroscopic electrodynamics or if you want a mix between
makroskopic and microskopic
maxwell theory.
