  1. The problems of movement behind the light barrier in the Special Theory of Relativity formation and developmentcontext Olena Shcherbak Dnepropetrovsk National University, Ukraine elena.scherbak@mail.ru

  2. One of the main postulates of the Special Theory of Relativity, such as the constancy of the velocity of light, arose to extensive controversies in the scientific world. Its acceptance as the main postulate, allowed refusing the ether theories and thus explaining the outcomes of Michelson and Morley’s experiments. • The theories, which allowed explaining Michelson and Morley’s experiments, thus giving an opportunity to remain within the framework of classic physics: • Ritz’s ballistic hypothesis: This theory was supported by W. Ritz (1908), Comstock (1910), Kunz (1910), R. Tolman, (1910), Ya. Grdina (1923) • Abraham’s theory, on the basis of the ether fixed theory, proposed the law of the velocity addition : Dnipropetrovsk National University elena.scherbak@mail.ru

  3. A. Einstein himself, in the paper of 1907, justified supraluminal velocity impossibility concluding from the character of our experience, which is not the main law Kirgnic D.А., Sazonov В.Н. in the paper “Supraluminal movement and the special theory of relativity” paid attention to this fact. A number of physicists, such as Terleckiy Ya. “Paradox of the theory of relativity”, Feinberg G. “On the possibility of Faster than Light Particles”, Bilaniuk О. and Sudarshan Е. “Particles Beyond the Light Barrier ”, in 60-s of the past century came to the conclusion, that supraluminal movements did not contradict the STR. The further push in the development of the theory of supraluminal motions belongs to Gerald Feinberg, who in 1967 brought in the concept of a supraluminal particle - tachyon.

  4. Conclusion proposed by L. Strum In the system S: OD=x, BD=U=ct, OD1 =-x1; B1D1=u1=ct1 tgφ = ; tgψ = ; XOA= OA, OA1– the cone intersection with the plane XU. At V>c, ψ< , and point B lies in the middle of the corner XOA, that is in "intermediate space". The same reasoning can be also conducted for point В1. When v > , that is tgφ > tgψ. The point B lies in the middle of хОх/ therefore has a negative coordinate U/. «…not only of the fact that the coordinate of time becomes negative, but also owing to the fact that the coordinate of time is negative only in the system S/ whereas in the other system S the given coordinate is positive. It demonstrates that only at the condition of theexistence of processes, which spread with the speed exceeding the velocity of light in any system S, only such speed of rectilinear and uniform motion of the other system S/ relatively S, is possible, at which the direction of time in the system S/ for such processes is opposite to the direction of time in the system S. Thus, the theory of relativity reduces to new consequences as contrasted with earlier version. … the possibility of speeds exceeding the velocity of light does not contradict the STR…» Dnipropetrovsk National University elena.scherbak@mail.ru

  5. Conclusion proposed byBilaniuk О. and Sudarshan Е.'s papers Having introduced the concept of the «particles with the negative energy», they noted, that «…the return sequence of events is supervised when point P lays below axis х. It is astonishing, that it comes exactly under the same conditions, at which the product > с2 (where, - the speed of a tachyon concerning the system S, -the movement speed of the system S/ relatively S). As it will be seen hereinafter, the interpretation of this coincidence of signs change is a clue to the sequent theory of superluminal particles…». The given principle was called the principle of rе-interpretation which asserts that the particles «…with negative energy, at first absorbed and then emitted, are emitted and absorbed in the return order…» Dnipropetrovsk National University elena.scherbak@mail.ru

  6. If to compare two conclusions of these authors: Strum L. Bilaniuk О. and Sudarshan E. Dnipropetrovsk National University elena.scherbak@mail.ru
