Neutrino's still going too fast

[Jeroen Vriesman]

What I mean is that the world for a neutrino is only a collection of magnetic material properties and nothing else.
So normally the lightspeed is c0/sqrt(er * ur),
Where c0 is the speed of light in vacuüm, er is the relative permitivity and ur is the relative permeability of the material.
But for the neutrino's it's c0/sqrt(ur) because for the neutrino there is no electric interaction with matter, just magnetic interaction.

So in a diamagnetic material the neutrino has a speed higher than c0, even if er >1.

That would also explain why they don't loose energy by cherenkov radiation.

They are traveling at the speed of light, it's just that for neutrino's the speed of light >c0

This is not in conflict with relativity, relativity just says that a particle with zero rest Mass will travel at maximum possible speed.
But this maximum speed is not lightspeed, it's c0/sqrt(er * ur), Where er=1 if electric interaction is irrelevant.

It would be easy to verivy by placing a strong diamagnetic material in the bram and see if they arrive sooner.

Relativity seems a bit more relative than expected.
