Massive Cosmic Test Shows Newton And Einstein Still Explain Gravity Accurately

Massive Cosmic Test Shows Newton And Einstein Still Explain Gravity Accurately Authored by Neetika Walter via Interesting Engineering, Scientists have tested gravity across some of the largest structures in the universe and found that it behaves exactly as predicted by long-standing physical laws. Galaxies and clusters trace gravity’s pull across the universe.iStock Photos Researchers led by University of Pennsylvania used data from the Atacama Cosmology Telescope to examine how galaxy clusters move across vast cosmic distances. Their results show that gravity weakens with distance in line with the inverse-square law first described by Isaac...
