Physicists discover cosmic glitch in gravity, challenging Einstein's theory

Physicists from the University of Waterloo and the University of British Columbia have uncovered a "cosmic glitch" in gravity, potentially shedding light on the universe's mysterious behavior on a cosmic scale.

In a paper published in the Journal of Cosmology and Astroparticle Physics, they suggest that Albert Einstein's theory of general relativity may not fully explain the accelerating expansion of the universe. Lead author Robin Wen explains that at cosmic distances, gravity appears to deviate around one percent from Einstein's predictions, prompting the team to propose a modification to the theory.

Coauthor Niayesh Afshordi believes this discovery marks the beginning of solving a cosmic puzzle that has puzzled astronomers and physicists for decades.
