Rejection of the Use of Thought Experiment in Physics

In physics, whenever we cannot do an experiment in the real world for physical, technological, financial or ethical reasons, we use from "thought experiment" . In this letter, we prove that sometimes a thought experiment may lead us to the wrong results; and to achieve the definitive and reliable results, all experiments must be done in the real world. Here we prove that thought analysis of an experiment before performing in the real world, namely thought experiment, is a wrong work.
