The new “Chameleon theory” can solve the mystery of dark energy

The Work of albert Einstein published in 1915, describes the nature and impact of large objects in space. The General theory of relativity (GTR) formed the basis of our understanding of the Universe. However, General relativity is not the only explanation of the action of gravity. Periodically, scientists have put forward alternative theories, although it should be noted that none of them is consistent with the experimental data to the same extent as the work of Einstein. Recently, a group of scientists from the University of Durham , published a study in the journal suggests that one of these alternative theories — known as the “Chameleon theory” — could actually explain how gravity works in certain situations.
Theory of Chameleon — the fifth fundamental force of the Universe?
As the researchers write, “the theory of the Chameleon — this class of theories alternative to General theory of relativity”. In this theory, in addition to the standard gravitational force, there is one more power — the so-called “fifth force”, because it differs from the other four types of fundamental interactions. In some tight areas , such as our Solar system, the theory of a Chameleon can not be verified, however, in the regions with low density extra strength can affect the principle of gravitation of celestial objects. This behavior of the theory, depending on the environment, gives it the name Chameleon. Moreover, advanced modeling on a supercomputer showed that galaxies can form in a Universe where the principles of the theory of the Chameleon.
The Researchers do not exclude that the results obtained can be essential for understanding such phenomena as black holes and the role they play in forming galaxies, and the nature of dark energy — the most mysterious force in the Universe, which is believed to be responsible for the accelerating expansion of the Universe. The General theory of relativity succeeded in explaining many phenomena and is one of the pillars of modern cosmology. However, the fact that the expansion rate of the Universe increases greatly puzzles researchers. In the framework of General relativity, the expansion rate is determined by the density of matter in the and account of all the known kinds of matter. According to General relativity, this rate must constantly fall.
The Accelerated expansion of the Universe is one of the biggest questions in modern cosmology. In search of dark energy models and modified gravity have been studied intensively. Theory of Chameleon — is a popular modified gravity model. The researchers emphasize that their results do not prove that General relativity is wrong, it should not be the only way to explain the role in the evolution of the Universe. The next step for the researchers is to validate the obtained results using the experimental data in the real world. However, in order to conduct the study, scientists will have to wait for the opening of the world's largest Square Kilometre Array radio interferometer, which is scheduled for next year.
