On a cosmological level, Einstein's general theory of relativity doesn't seem to be entirely correct. A research team has a solution to the “cosmic error”

Munich – In 1915, Albert Einstein presented his theory of general relativity, which is still in effect today. For example, it very accurately predicted what black holes look like, and the first image of a black hole confirmed this theory. The existence of so-called gravitational lenses – massive objects in the universe that act as a magnifying glass for the objects behind them – also confirmed the theory of relativity.

“This model of gravity has been important in everything from the Big Bang theory to imaging black holes,” says Robin Wen of the University of Waterloo in Canada. The researcher continues: “But when we try to understand gravity at the cosmic level, at the level of galaxy clusters and beyond, we encounter clear contradictions with the predictions of general relativity.” “It's as if gravity itself no longer quite fits Einstein's theory.”

“Cosmic error”: Gravity weakens by one percent at long distances

According to Wayne, this phenomenon is called “cosmic error.” “Gravity gets weaker by about one percent when it comes to distances of billions of light years.” For more than 20 years, physics and astronomy have been trying to develop mathematical models that can explain these discrepancies in the theory of relativity. It appears that Wen, in collaboration with a research team, has now succeeded in developing such a model. It was work In the specialized magazine Journal of Cosmology and Astroparticle Physics published.

“Almost a century ago, astronomers discovered that our universe is expanding,” says co-author Nish Afshordi in one of the articles. notice. “The farther away the galaxies are, the faster they move, to the point where they appear to be moving at almost the speed of light, the maximum allowed by Einstein's theory. Our results suggest that Einstein's theory may be inadequate on these scales.

The research team is modifying and expanding Einstein's theory of relativity

The new “cosmological error” model modifies and extends Einstein's mathematical formulas so that the discrepancy in some cosmological measurements is resolved without affecting the working part of general relativity. “Think of it as a footnote to Einstein's theory,” Wynn points out. “Once you reach the cosmic scale, different conditions apply.”

Fellow researcher Afshordi is certain that this new model could be the first clue to the cosmic puzzle we are just beginning to unravel across space and time. (unpaid bill)
