![]() ![]() "For an example application, we studied spherically symmetric solutions and the evolution of the universe at early and late times. The new theory's indications are consistent with experimental observations. As an example, the author tested the new theory by calculating two stages of the development of the universe-inflationary and accelerating expansion. The astrophysicist showed that the new gravitational model is consistent for different environments and can be used in astrophysical and astronomical research. One describes temperature–entropy, and the second describes charge and interaction. ![]() The field equations were supplemented with two terms. After the transformations, we have an equation that resembles the classical Einstein equation in form, but with different factors and constants. ![]() This is an equation that shows how the indicators of its components change in a thermodynamic system. He started from the so-called Gibbs–Duhem relation. However, in any case, the law of conservation of energy-momentum can be violated at high energy levels," Hamidreza Fazlollahi, a graduate student at the Educational and Scientific Institute of Gravity and Cosmology of RUDN University said.įazlollahi has built a new gravitational model. "This can be explained in different ways. So it is possible that at high energy and/or within the event horizon of black holes, spacetime curvature and gravity deviate from Einstein's general theory of relativity. For example, in string theory, Einstein's classical equation is just the first term in an infinite series of gravitational corrections. It has led to dozens of attempts to treat it as a low-energy theory. "The problem of non-renormalizability of Einstein's gravity is well known. The study is published in The European Physical Journal C. Technically, this means that mathematical flaws appear that cannot be eliminated.Ī RUDN astrophysicist has built a new theory of gravity, in which the "law of conservation" of the energy–momentum tensor is not required. For example, at sufficiently high energies the so-called non-renormalizability problem arises. However, this assumption is not always justified. Just as, for example, in ordinary mechanics, the law of conservation of energy is fulfilled. In general relativity, the energy–momentum tensor is considered to be unchanged, or conserved. ![]()
