Very true scientists, such as Rutherford, Soddy, Michelson, Sagnac, Lenard, Larmor, McMillan and others, have claimed, that the Theory of relativity is wrong. Even Poincare and Einstein are hinted something similar. Classical physics is far from simple, already during the XIX century has been spoken about things like gravity waves, nuclear power and variable mass. Theory of relativity as a whole, is based only on the hypothesis, that the speed of light in Euclidean empty space is, invariant universal constant. But in reality this velocity is variable, in Newtonian sense. Newton's emission theory of light, has been proven through many experiments, for example by those of Michelson, Sagnac and Fizeau. Also, the velocity of photons in one ray, is variable with respect to lateral observer, and is consistent with the classical law for velocity addition.
