A number of physicists have claimed that the neutrinos emitted by supernova SN 1987A constitute counter-evidence against the OPERA results which indicate neutrinos travelling at superluminal speeds.
The argument goes as follow. Neutrinos emitted by the SN 1987A supernova arrived approximately three hours before visible light emitted by the same source. Considering the estimated distance of the SN 1987A, if neutrinos had been travelling at speeds comparable to those measured by the OPERA group, the supernova neutrinos would have arrived not three hours but approximately four years before visible light from the same source.
Although the argument appears to make sense, it holds only if the superluminal speed measured by the OPERA group is taken as being the absolute speed of the neutrinos. But if, as QGD suggests, the superluminal speed of the OPERA neutrinos is the relative speed between neutrinos emitted by CERN and the target as Gran Sasso, that is, the difference between the measured superluminal speed and c corresponds to the absolute speed of the Earth along the CERN-Grand Sasso axis, then the argument loses its meaning.
Thus, according to QGD, the absolute speed of the OPERA neutrinos is the same as the absolute speed of the SN 1987A neutrinos, which is the exactly speed of light.
That said, the relative speed between the supernova neutrinos and the Earth may be different from the speed of light. And since neutrinos can travel only at the speed of light, any difference between the measured speed of neutrinos from a source and c should be attributed to the absolute speed of the Earth along the axis that connect the source to the target or detector. This can be used as the theoretical foundation for the construction of neutrino telescopes. Neutrino telescopes would allow much more precise measurements of cosmic distances and speed than what are possible using current methods.
A complete discussion of the principles behind neutrino telescopes will be included in volume two of my Introduction to Quantum-Geometry Dynamics.
