Article Actual Problems of Modern Physics, Astrophysics, and Cosmology

The lack of experimental data, the ambiguous representation of the real picture of the world in most models, theories, and hypotheses about the Universe, and the huge scale factor of the issues under study, have led to the fact that many problems have arisen in modern physics, astrophysics, and cosmology. Among this set, the most relevant and debatable are the following problems:

- the optimal choice of the metric tensor for solving the Einstein equation of the General Theory of Relativity, which most fully corresponds to modern experimental data. As a consequence of this optimal choice, there is a need to correct the basic equations of cosmology, which is also due to new experimental measurements of the Hubble constant;

- an ambiguous experimental estimate of the Hubble constant;

- stability of constants, the maximum transmission rate of physical interaction;

- dark energy and dark matter;

- correct choice of the coordinate system in cosmological studies;

- the physical nature of the cosmological constant;

- representations of the general structure of the Universe;

- concepts of the Big Bang, singularity point, initial conditions, and limitations;

- connections of the Standard Model of physics with gravitational interaction;

- understanding the features of the quantum-wave nature of the gravitational field;

- the physical nature of time and its relationship with real space;

- the optimal choice of the quantum-wave model of the gravitational field of the observable Universe and the development on this basis of its physical and mathematical description, which corresponds to the modern set of experimental data in astrophysics and cosmology;

- estimates of the scale factor between the microcosm and the macrocosm of the observable Universe; - estimates of the mass of distant objects of the observable Universe;

- carriers of the gravitational field and dark matter.
