The Atacama Cosmology Telescope - A Test of the #GravitationalForce Law on Cosmological Scales Using the Kinematic Sunyaev-Zeldovich Effect: https://arxiv.org/abs/2604.14327 -> Gravity follows Newton and Einstein’s rules, even at cosmic scales: https://penntoday.upenn.edu/news/gravity-follows-newton-and-einsteins-rules-even-cosmic-scales - by tracking galaxy clusters hundreds of millions of lightyears apart, Penn physicist Patricio Gallardo and collaborators find that the laws of gravity written by Newton and Einstein still hold, leaving little doubt that invisible dark matter exists.
