The Theory of Relativity does not show to us a strange behaviour of nature. Strange may be, however, why it could be so widely accepted. It shows to us that every day's methods must not be used in an environment where they are due to fail. Albert Einstein's methods of defining simultaneity and determining it don't match. This paper is intended for nonprofessionals in this matter and does not use mathematical notation.
We present a thought experiment similar to Einstein's train and lightning example. This experiment yields very paradox consequences. Some basic knowledge about the special theory of relativity is assumed. Supporters of the Theory of Relativity are invited to give answers.
In the derivation of his Special Theory of Relativity Einstein uses a definition of simultaneity and a way of determining it which are not compatible. Although the way of determining simultaneity is adequate for common daily problems, it is in contradiction to the concept of synchronized clocks given by himself. Einsteins method of determining simultaneity is some kind of ?habit of thinking? while a different method is a ?necessity of thinking?.
The observations predicted by the theory are artefacts produced by this incompatibility.
