They will prefer to sink into the absurd and the ridiculous loss of

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).

The, "gravitational waves", happen to go at whatever "c_g" is,
not whatever "c" is.
