 That is not a valid science.

 And tachyons? Yes?

 And they don't violate causality.

It's impossible.
They will prefer to sink into the absurd and the ridiculous loss of causality.
Note that the speed of neutrinos is c, because their transaction is instantaneous (zero natural time).
It is true that if a supernovae explodes, the neutrinos, whose speed is not modified by the interactions of intergalactic gases, can arrive slightly before the light (supernovae of 1987).
But this does not come from the fact that they are faster than light (this is impossible) but from the fact that light is slightly slowed down by the presence of tiny quantities of gas present in interstellar environments (this which is no longer the speed of light in a perfect vacuum).
