It is not a secret, that in our truly dizzying era of change, science has already begun to advance at a much more impressive pace. Thanks to what, humanity is now quite successfully mastering new unexplored horizons, revealing to itself thereby the next hidden curtains of existence. As for potential time travel, a long before the start of serious academic research, this extravagant theme was repeatedly touched upon in popular works of a whole host of wide-famous sci-fi writers. Thus, the Englishman Herbert Wells described us in his novel “The Time Machine” the flying to the future; and the American Ray Bradbury illustrated very brightly and fascinatingly analogical voyages to the past in the story "A sound of Thunder". In their turn, leading Soviet specialists also tried to keep up with the recognized foreign colleagues. In particular, we are talking here first of all about the Strugatsky brothers, V.A. Chernobrov, S.V. Krasnikov and, of course, about Russian-Danish academician Igor Novikov. And it’s just to the critical analysis of some enough controversial views and hypotheses of the last name (or, to be more precise, the principle of self-consistency speculatively put forward by him) that most of given article is devoted. Wherein prime attention here is paid to proof of the absolute conceptual prohibition on moving into the past. For de facto the maximum that could be implemented in the present case (and plus with a fair amount of skepticism and sober irony), is test sending of some robot-like portable systems which would not be spotted allegedly by local retro-natives there. Although, in general, even such compromise proposal does not at all pretend to originality, since it echoes, anyway, with the main postulates of modern ufology. And in summary, the author leads his reader to a quite reasoned conclusion that unraveling the most complex outlook problems of existence, it is better, obviously, to trust philosophers rather than techies!
