Study on Universes Being Invisible on Earth Outside the Portals Are Visible in Portals

The authors of the existing version of the special theory of relativity had to use the principle of light
speed non-exceedance to explain relativistic formulas obtained therein within the space of real
numbers. The principle implied existence of only our visible universe and absence of physical content
in imaginary numbers. However, since the principle is just a postulate, i.e. an unproven assumption, it
has always carried little credibility. The paper refutes the principle by the experimentally proven
principle of physical reality of imaginary numbers. As follows from the principle of physical reality of
imaginary numbers, relativistic formulas of the existing version of the STR are wrong and incorrectly
explained, and conclusions drawn from them are misguided. In other words, this version is incorrect1
and, thus, the STR was not actually created in the 20th century. Moreover, it could not be created in
the 20th century, as its creation required experimental data obtained in the 21st century. The paper
provides an alternative version of the STR containing relativistic formulas corrected given
experimental data obtained in the 21st century. These formulas imply that instead of the Monoverse,
whose existence is supposed in the existing version of the STR, there is a Multiverse, whose
universes are mutually invisible (and the invisibility is explainable) and therefore it has been referred
to as hidden. The paper explains that existence of invisible universes of the hidden Multiverse gives
rise to the phenomenon of dark matter and dark energy that is actually a sort of optical effect
(however, not electromagnetic, but gravitational), a shadow, rather than some physical substance2. It
also explains that existence of other invisible universes outside the hidden Multiverse gives rise to the
phenomenon of dark space. Invisible universes are claimed to really exist, which can be
experimentally proved by astronomical observations in portals, where universes not visible outside
portals become partially visible. Therefore, constellations observed in the starry sky inside the portals
are different from those observed in our visible universe. The corrected alternative version of the STR
proves the existence of invisible and, therefore, considerably unknown world that has yet to be
studied by science of the future. The alternative version of the special theory of relativity can also
successfully solve other issues of astrophysics. In particular, it can explain where antimatter is located
and why it does not annihilate with matter, as well as where tachyons are located and why they don’t
violate the principle of causality, etc.
