Rejecting the Use of Thought Experiment Results in Physics

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