In real life a real scientist must test his own hypothesis and the hypotheses of others.
They must devise and test a hypothesis which lends itself to specific predictions offering a means of testing its validity. All observation, in a special field of science, must be either for or against your hypothesis or my hypothesis, if the observation is to advance science. Science advances only by investigators who know how to disprove the empty theories and are already working on it. Science advances only by disproofs. It can take many years before the scientific community gets it.
