General Relativity
4 reportsThe most informative angles on General Relativity involve mathematical predictions; experimental tests; and symmetries and limiting cases. The account anchors symmetries and limiting cases in precision measurements and uses independent experiments to test whether the pattern extends beyond one dataset; interpretation remains cautious because agreement within one regime does not guarantee validity beyond tested conditions.
Quantum test reveals Einstein's gravity holds for falling atoms
A new experiment using ultra-cold rubidium atoms has measured how gravity affects quantum waves, providing the first direct test of Einstein's equivalence principle in the quantum regime
Quantum Computers Face Key Hurdles in Simulating Particle Physics
Quantum computers are being developed to simulate quantum systems that challenge classical supercomputers, but significant technical and theoretical barriers remain before these machines can reliably model particle physics or unify quantum information with general relativity
Black Hole Thermodynamics Updated Beyond Hawking's Original Theory
Physicists have proposed a new framework for describing black hole energy loss, extending thermodynamic laws to dynamic black holes and addressing a key limitation in Stephen Hawking's classic model
Gravitational Wave Data Reveals Black Hole Event Horizon Properties
Researchers have extracted direct physical parameters from a black hole event horizon using an unusually strong gravitational wave signal, providing new experimental access to a region previously studied only through theory
