WebAug 25, 2024 · In this article, Clifford M. Will and Nicolás Yunes survey the new and future tests of Einstein's greatest achievement, the theory of general relativity. WebUsing this comparison between theory and observation, no evidence was found that gravity is different from Einstein's theory on scales larger than 130 million light years. This limit corresponds to a hundred-fold improvement on the bounds of the modified gravitational force's range that can be set without using the cluster data.
