Controversies arise when specialists disagree on some particular issue. This normally occurs in any scientific brunch. We analyze some controversies, which have a good cause in Special Relativity. The paper does not question Special Relativity Theory but it challenges changing deeply held academic beliefs about imaginary experiments in Special Relativity Theory.

The wide availability of information has led to the fact that students are well aware of the difficulties of existing physical theories. In this article we analyze some logical paradoxes of the special relativity theory (SRT), concerning the time dilation and length contraction. The Lorentz transformations and the relativistic law for velocity addition are considered in detail. The notion of relativity and the transverse Doppler effect are discussed. The whole complex of numerous paradoxes in the special theory of relativity worries us by further complications.

The special theory of relativity has been honored with high interpretations about human mental performance for more than a century and it played a role in increasing interest in science. With the improvement of methodology and its becoming more competent, the flaws of the theory and its superficial analyzing became transparent, and in its 200 th anniversary it became the case for the error file in the history of science. Through this widely known example, this study summarizes the reasons why humanity is deceived oneself while searching for reality.

After 100 years, Einstein's Special Relativity Theory (SRT) is still both widely believed and widely disputed. This paper claims the cause is insufficiently precise and ambiguous wording. The deductions that form the foundation of "Special Relativity" require only the first 5 pages of SRT. While the remainder of SRT and popular SRT academic papers are replete with complex math, SRT's 5-page foundation uses only a very simple analysis of a simple imaginary experiment. Its deductions are arrived at using only high school level math. Using verbatim wording, this paper provides clarifying annotations and calculations that describe every individual assertion in the foundation. The conclusion is that the foundation clearly rejects the 3 basic postulates of SRT. Given this sound rejection, the remainder of SRT should be viewed as a misleading math exercise that develops coordinate transformations for an impossible set of physics principles. The conclusion also suggests that all uses of the SRT "beta" formula in later papers and research, that rely on SRT for the validity of the "beta" model, only lead to fictitious results.

The speed of light postulate is closely examined from the perspective of two inertial reference frames―unprimed (‘stationary’) and primed (‘traveling’)―in relative motion, revealing that the speed of light postulate actually requires length contraction with respect to the unprimed reference frame, and length expansion with respect to the primed frame. It is shown that when symmetry is imposed on the inverse length transformation (i.e., to make it exhibit the same length contraction from the perspective of the primed frame), the common length contraction factor becomes nothing but the Lorentz contraction factor .  However, this would necessarily result in  1, implying that the frames are being at rest with respect to each other, and thus refuting the special relativity predictions! When the coordinate’s transformation symmetry assumption is applied on the direct transformation resulting from the light speed postulate―which is shown incompatible with this assumption―, the Lorentz transformation and its inverse are erroneously obtained; it is shown to be restricted to certain coordinate relations, resulted in mathematical contradictions, and thus demonstrated to be unviable.

In this stroll about the Special Relativity Theory, I analyze Einstein’s insights about the actual meaning of his Relativity Theory. This analysis clarifies us about the way that the Special Relativity Theory should be understood, and help us to see if one really needs to be a genius for fully understanding it. It is found that the Special Relativity Theory is consisting of two independent concepts, of which the basics are unveiled and put in the right context of physics. The experiments that are claimed to prove the Special Relativity Theory are scrutinized in the context of the findings.
