[time-nuts] The GPS velocity of light versus neutrinos

[Bob Bownes]

Keep in mind that a common view or LOS light method will have a
problem with the variability of the medium density along the path
being unknown.
You could do it in a vacuum however.

I come back to the base question of 'since the speed of light varies
depending on the medium, does the speed of the neutrino also vary, and
if so, how?'
