A study by an international team of astronomers has found that even the largest, most distant structures in the universe follow similar gravity rules to those of Isaac Newton and Albert Einstein. The study, published in Physical Review Letters, tested cosmic observations against Albert Einstein's general relativity, which is built upon Newton's basic laws of gravity. This discovery disproves alternative theories that modify fundamental rules of gravity to explain observational inconsistencies in cosmology. The researchers concluded that modified laws ofgravity were not as successful as the conventional equations. Despite not having found direct evidence for dark matter, there is strong consensus that its presence helps to explain many unexplained phenomena in the cosmos.
