The laws of physics would not be as “stable” as scientists imagined

Australian researchers have just made a strange and exciting discovery. According to their work, the electromagnetic force could vary in certain parts of the Universe. Explanations.


The Universe would have a partially dipolar structure

With gravity, the weak nuclear force and the strong nuclear force, theelectromagnetism is one of the four fundamental interactions ofUniverse. To calculate the intensity of the electromagnetic interaction between electrons and the photons, scientists rely on the fine structure constant, whose value can currently only be estimated experimentally.

In an article published in Science Advances, researchers fromuniversity of new south wales ((UNSW) presented new measurements of the light emitted by a quasar located 13 billion light years away, which have enabled them to reaffirm the minute variations in the fine structure constant mentioned in previous work, which could have enormous implications for current physics.

Our work suggests that the fine structure constant is different in certain parts of the Universe. This suggests that there could be a direction in the Universe, and that it would therefore have a partially dipolar structure. What remains really very strange “Explains the astrophysicist John Webb, lead author of the study.

“This opens the way to exciting new concepts in the field of physics”

In order to measure this electromagnetic force as it would have appeared when theUniverse was much younger, the researchers relied on the data and images obtained by the Very Large Telescope ((VLT), installed at Chile.

These data suggest that electromagnetism gradually increases as we look far and seems to decrease in the same way in the opposite direction, while the fine structure constant remains strictly the same in other directions of the cosmos. “, Note John Webb. And it turns out that this idea of ​​directionality inUniverse was also supported by an independent American team, studying the nature of X-rays and identifying a similar cosmic alignment.

The teacher Webb asserts that if these results are supported by new studies, this could notably explain the presence of life in theUniverse. While the electromagnetism changes in different parts of the cosmos, suggesting that theUniverse either less isotropic provided that, could lead to a revision of the basic concepts underlying modern physics.

The standard model itself is based on Einstein’s theory of gravitation, which explicitly assumes the constancy of the laws of nature. If such fundamental principles turn out to be only approximations, this opens the way to exciting new concepts in the field of physics. “Concludes the researcher.
