AI framework links gravitational waves and radio afterglows
Los Angeles CA (SPX) Feb 02, 2026 When two neutron stars collide, they generate gravitational waves and light across the electromagnetic spectrum, from intense gamma ray flashes to faint radio signals that can persist for years. These multi-messenger events contain rich information about the physics of compact objects, their environments and the formation of heavy elements, but extracting that information efficiently has proved challenging. A collaboration led by researchers at the U.S. Department of Energy's Argonne National Labo ... read more |

Is gravity quantum?
Boston MA (SPX) May 21, 2025 One of the most profound open questions in modern physics is: "Is gravity quantum?" The other fundamental forces - electromagnetic, weak, and strong - have all been successfully described, but no complete and consistent quantum theory of gravity yet exists. "Theoretical physicists have proposed many possible scenarios, from gravity being inherently classical to fully quantum, but the debate remains unresolved because we've never had a clear way to test gravity's quantum nature in the lab," s ... read more
