The Physical Essence of Observer Horizon (Event Pseudo-Horizon) and Schwarzschild Sphere. Cosmological Age of the Universe*

Abstract

Pavlo Danylchenko

The possibility to avoid physical realizability of cosmological singularity (singularity of Big Bang of the Universe) is substantiated. This can take place in the case of counting of cosmological time in frame of reference of spatial coordinates and time (FR) not comoving with matter, in which by the Weyl hypothesis galaxies of the expanding Universe are motionless. It is proved that only in the case of the joint application in the Universe of a metrically homogeneous scale of unified gravithermodynamic (beginningless cosmological) time and a dynamic gravitational field, which ensure the invariance in space and time of the vacuum velocity of light and the Hubble constant, it is possible to ensure not only the general covariance of all physical laws, but also the gravitational-relativistic invariance of thermodynamic parameters and potentials of matter. It is the beginningless cosmological time together with the infinite dynamic space of the Universe that form a global dynamic frame of reference of spatial coordinates and time of the people's world (GDFRPW), which is equivalent to the frame of reference comoving witch the expanding Universe.
