New theory of physics suggests that the universe is not expanding after all

The results of a new study, published in Classical and Quantum Gravity, suggests that the theory of the expansion of the universe may be wrong. The new approach also provides clues to the mystery of dark matter and dark energy, which scientists believe account for about 95% of the energy and matter in the universe.

The author of the scientific article is Lucas Lombrisier, theoretical physicist and lecturer at the University of Geneva. He casts doubt on the generally accepted theory that the universe is constantly expanding due to dark energy. Its confirmation is the redshift, that is, the shift of the wavelength of light to the red end of the spectrum is the stronger, the more the galaxies emitting this light are removed from the Earth.

According to Lombrisier's mathematical interpretation, the universe is in fact flat and static, in line with the assumption that Einstein once held. What we have mistaken for evidence of the expansion of the universe is actually explained by the evolution of the mass of particles over time.

In the model of the universe proposed by the physicist, protons and neutrons arise from a field that pierces space-time. The mass of this field changes with time, which also affects the mass of particles born in it. But this mass shift is explained by evolution, not by the expansion of the universe, and it is the change in the field that leads to the redshift.

A static universe also explains the problem of dark matter. According to Lombrisier, a change in the field can lead to the formation of an axion field (axions are hypothetical particles that dark matter can consist of). With dark energy, it is even simpler: the effects associated with it are explained by a change in the mass of elementary particles, and the need for the existence of dark energy disappears altogether.

This is an interesting theory, but it needs to be treated with caution, as some of its elements cannot be verified by observation - at least in the near future.
