A group of Canadian scientists from the University of Waterloo and the University of British Columbia have discovered a potential “glitch” in the gravity of the Universe. It turns out that from a large distance the gravitational effect begins to weaken. The research was published in the scientific journal broadcasting Journal of Cosmology and Astroparticle Physics (JCAP).
For the last 100 years, physicists have relied on Albert Einstein’s theory of general relativity (GR) to explain how gravity works in space. General Relativity suggests that gravity affects not only three physical dimensions but also a fourth, time.
“When we try to understand gravity at the cosmic scale, at the scale of galaxy clusters and beyond, we encounter apparent inconsistencies with the predictions of general relativity. We call this discrepancy the “cosmic glitch”: at distances of billions of light years, gravity weakens by about 1%,” explained Robin Wen, lead author of the project.
According to scientists, this may be due to the expansion of the universe, and the further away galaxies are, the faster they move, approaching the speed of light.
The team is trying to develop a new mathematical model to resolve the discrepancy in cosmological measurements.
