Discussion on the Comparative Analysis of Existing and Alternative Version of the Special Theory of Relativity

The article explains that: 1) relativistic formulas obtained in the existing version of the special theory of
relativity (STR) are incorrect; 2) relativistic formulas obtained in the existing version of the STR are
explained incorrect due to the use of the nonexistent in nature principle of light speed nonexceedance;
3) conclusions on physical unreality of imaginary numbers and existence of only our
visible Monoverse drawn from relativistic formulas of the existing version of the STR are incorrect due
to the use of the incorrect principle of light speed non-exceedance. In other words, the existing
version of the STR created in the 20th century is not quite true. Moreover, the correct STR could not
be created in the 20th century, since 1) the principle of physical reality of imaginary numbers refuting
experimentally the postulated (i.e. being an unproven assumption) principle of light speed nonexceedance
was published only in the 21st century; 2) experimental data whose mathematical
analysis discerned the quaternion structure of the hidden Multiverse consisting of twenty to twenty-two
invisible parallel universes in six-dimensional space were obtained by WMAP and Planck spacecraft
only in the 21st century; 3) explanation of the way how astronomical observations of constellations of
the starry sky in portals can experimentally prove the existence of invisible universes was published
only in 2019. Therefore, the article presents an alternative version of the STR, free from the
shortcomings of its existing version. Other relativistic formulas that have been obtained in the
alternative version of the STR are explainable both at sub-light and hyper-light speeds, and for real
and imaginary values of all quantities corresponding to these formulas. Therefore, the principle of light
speed non-exceedance is excluded from this version of the STR. For the same reason, the alternative
version of the STR states that there is a Multiverse of mutually invisible parallel universes, rather than
a Monoverse, since all the mutually invisible parallel universes are relative to each other beyond the
event horizon. It also explains how the existence of these invisible parallel universes can be proved by
astronomical observations in portals. Moreover, the WMAP and Planck spacecraft data are used in
the alternative version of the STR to clarify the structure of the hidden Multiverse. Their mathematical
processing has testified that the hidden Multiverse has a quaternion structure and contains twentytwenty
two invisible universes in six-dimensional space.
