According to the author of the published post European Physical Journal CThe problem of general relativity is the so-called laws of behavior. This term refers to rules relating to physical systems isolated from the environment. These laws assume that specific physical quantities remain constant in such systems.

General relativity uses the concept of curved space-time. In order to describe how the energy and momentum of fields are distributed in space-time and how they interact with the gravitational field, physicists use what is called the energy-momentum tensor, which can be compared to the energy and momentum in ordinary mechanics.

According to the theory proposed by Albert Einstein, the tensor of energy and momentum should be constant, although this cannot always be justified. As a result, at sufficiently high energies, the problem of non-normalization may arise, which manifests itself in mathematical errors that are impossible to eliminate. Fadlallah claims that by eliminating the law of conservation of energy and momentum tensors, general relativity can be improved.

## Fadlallah's formulation of general relativity has been shown to provide results consistent with observations

As the author of the aforementioned post explains, the problem of non-renormalizability of gravity is well known. For this reason, various procedures have emerged, for example in the fact that Einstein's classical equation in string theory is only the first term in an infinite series of gravitational corrections. As a result, at high energy, such as inside the event horizon of a black hole, the curvature of spacetime and gravity deviate from Einstein's general theory of relativity.

How do we explain this? There are many ideas, but in each case the law of conservation of energy and momentum may be violated at high energy levels. In response to this problem, Fadlallah developed a new model of gravity. Use the Gibbs-Duhem equation relating how the indices of its components change in a thermodynamic system. In the end, an equation was created that resembled Einstein's classical equation, but had different coefficients and constants. Field equations contain two additional expressions: those that describe temperature, entropy, charge, and reactivity.

More importantly, in this model, the new model is shown to be consistent across different settings and can be used in research. To prove the usefulness of his model in practice, its author carried out calculations relating to two stages of the evolution of the universe, i.e. inflation and accelerated expansion. The results obtained were consistent with the observational results. Since the model showed no inconsistencies regarding Einstein's gravity of the vacuum, this is great news for Fadlallah and his achievements.
