could relativity proof have been falsified?

if that was true then negative refraction would implied negative refracted light is faster than normal light

refraction is very misterious i dont take mainstream interpretation

edit:

anyway the only prove i have light is instant and therefore cause and affect is simultaneous allowing tt is that the bending of light that proves light is slow is false because of sun atmosphere refraction

if something is fake the opposite is truth
