suggest dimension hops as the means for neutrinos traveling faster
than light, as measured in the CERN OPERA experiment, described by
Adam et al., "Measurement of the neutrino velocity with the OPERA
detector in the CNGS beam" here:
http://arxiv.org/abs/1109.4897
The arrival time of the neutrinos across a 730 km distance was 60.7
ns early, representing 2.48x10^-5 relative difference vs light travel
time.
This measurement conflicts with early arrival time data for neutrinos
from supernova. The New Scientist article quotes Marc Sher of the
College of William and Mary in Williamsburg, Virginia, "It's not
reasonable." ... "If neutrinos were that much faster than light, they
would have arrived [from the supernova] five years sooner, which is
crazy," says Sher. "They didn't."
This implies a difference in travel speed in matter vs vacuum for the
neutrinos.
That's a possibility. Another is that this implies an extra difference
in travel speed in air vs. vacuum for light.
The electromagnetic signals sent by the gps systems are delayed a little
bit more than expected according to current theory. And that becomes
apparent only when compared with neutrino speeds, which are unaffected.
This is consistent with the Cahill and Kitto paper about the non-null
results of Michelson & Morley type experiments and the relation with the
refractive index of the medium:
http://arxiv.org/abs/physics/0205065
Interestingly, the 7.5 km/s reported difference in neutrino speed is in
good agreement with the 8 km/s result estimated for Michelson & Morley
type experiments in air.
And a third possibility: the underground distance estimation between
laboratories is wrong according to current theory. This can be the case,
by example, if unaccounted for length contraction is happening due to
gravitational effects. I would search for the difference in height
between both laboratories, the way to estimate length contraction due to
gravitational effects, and the estimated intensity of the gravitational
field at the neutrino beam mean travel depth.
