No there are no famous reputable scienctist who reject relativity, not anymore, they used to. But the experiments thatprove it keep pouring in so there are very few left that reject it.
You can disagree all you want, but the fact remains reality proves it to be true. We **must** use relativistic equations to solve tons of seperate problems that cant be solved otherwise. We have proven beyond any doubt that the equations for relativity dictate the results they claim to.
So any issue you have with the hypothesis is on your lack of understanding, nothing more.
