Cosmic Gravity Holds Its Ground Across Galaxy Clusters
TL;DR Summary
Using data from the Atacama Cosmology Telescope and the kinematic Sunyaev–Zeldovich effect, researchers tracked hundreds of thousands of galaxy clusters across hundreds of millions of light-years and found gravity obeys the inverse-square law on cosmological scales, aligning with Newtonian and Einsteinian gravity, reinforcing dark matter as the source of extra gravitational effects and challenging alternative gravity theories like MOND.
