What is phyiscs
Physics is a science. Science works according to the scientific method. The scientific method accepts only reason, logic, and experimental evidence to tell among what is scientifically correct and what is not. Scientists do not simply believe - they test, and keep testing unless satisfied. Just because some "big scientist" says something is right, that thing does not become a fact of science. Unless a discovery is repeatedly established in dissimilar laboratories at dissimilar times by dissimilar people, or the similar theoretical result is derived by clear use of established rules, we do not accept it as a scientific discovery. The real strength of science lies in the fact that it continually keeps challenging itself.
