Einstein predicted how gravity would work on the largest scales. And he was right, new research suggests

His model of gravity showed that Newtonian gravity, which has dominated astronomy and physics…

Saturday Quote: Everything that glitters is plastic. It awakened the diversity of trees. the gravity basin in which we live
A data visualization of the movement of galaxies within structures called gravitational basins. The Milky Way is a red dot. Credit: University of Hawaii This week, astronomers considered whether dark energy changes over cosmic time scales. Through neutron analysis, physicists have revealed that some early Iron Age swords have recently been altered by fraudsters to make them more historically exciting.…

Theoretical physicists develop method to model the central theory of quantum gravity in the lab
Illustration of the theory used to model quantum gravity: The lattice simulates a curved space-time. Near the boundary, the lattice becomes denser due to the curvature. Interacting electrical signals in the bulk (yellow, red, and blue lines) simulate the gravitational dynamics. The dynamics in the bulk and at the outer boundary correspond to each other. They are consistent with the…
