Yes he's not up there with the top guys in understanding, but I'm sure that not only does he know that it should be spelled kaon, but that he also knows what a koan is.
Considering the small difference in speed I suspect we are dealing with something closer to virtual particles in a vacuum slow down light and physical particles. It's not drag because virtual particles don't remove energy from the system but you get some propagation delays. It just so happens that gravity waves also propagate the speed of Neutrino etc. and relativity while nearly true has some edge cases. <- wild ass guess 1. Neutrino's ignore curved space time <- wag 2. Neutrino's time travel <- wag 300.
