# Theory of relativity is 'updated' after astrophysicist eliminates important law

Published for the first time in the work Mathematical Principles of Natural Philosophy, in 1687, Newton's universal theory of gravity written by physicist and mathematician Isaac Newton was used to explain the concepts of physics.

In 1915, Albert Einstein proposed the theory of general relativity and expanded Newton's concepts, as the hypothesis was considered incomplete in relation to some concepts. Newton's theory isn't perfect, but Einstein also knew that his version couldn't explain everything about physics either.

According to a new study published in the scientific journal The European Physical Journal C, an astrophysics student at the Peoples' Friendship University (RUDN) in Russia,** extracted a law that can improve the theory of general relativity.**

According to Fazlollahi, **removing a conservative mathematical law of energy and momentum could improve the theory of general relativity** and overcome some obstacles involving Einstein's work.

The student states that general relativity tends to have problems integrating with quantum mechanics, so he is looking for a new way to explain the emergence of gravity from the curvature of space-time.

“Einstein's non-renormalizability problem of gravity is well known. This has led to dozens of attempts to treat it as a low-energy theory. For example, in string theory, Einstein's classical equation is only the first term in an infinite series of gravitational corrections. Therefore, it is possible that, at high energies and/or within the event horizon of black holes, the curvature of spacetime and gravity deviate from Einstein's general theory of relativity,” he said student Hamidreza Fazlollahi, associate of the Educational and Scientific Institute of Gravity and Cosmology at RUDN.

## Updated theory of relativity

The astrophysicist explains that, by abandoning some of the fundamental assumptions of the theory of general relativity, it is possible to explore a new way of describing gravity based on the curvature of space-time. Fazlollahi states that he turned to relativistic thermodynamics to find energy and momentum transformations similar to those used in Einstein's theory.

Albert Einstein's work became popular among scientists around the world, after all, it is responsible for explaining some of the most complicated concepts in physics.

However, it is important to highlight that the theory cannot explain everything and is probably wrong on some level. That's why, **Scientists like Fazlollahi try to find new ways to explain some concepts that are not yet completely understandable.**

“The astrophysicist demonstrated that the new gravitational model is consistent in different environments and can be used in astrophysical and astronomical research. As an example, the author tested the new theory by calculating two phases of the Universe's development — inflationary and accelerated expansion. The indications of the new theory are in accordance with experimental observations”, describes an official statement.
