Twin black hole mergers test Einstein's general relativity
Two black hole collisions detected in late 2024 have provided unprecedented tests of Einstein's general theory of relativity. The events, captured by the LIGO-Virgo-KAGRA Collaboration, revealed unusual spins and possible second-generation black holes. These detections confirm theoretical predictions with high precision and probe for new particles.
Black Hole Merger Supports Hawking's Theorem
Astronomers announced on September 17, 2025, the detection of a black hole merger that provides strong evidence for Stephen Hawking's area theorem. Observed via gravitational waves, the event aligns with predictions that black hole surface areas cannot decrease. This bolsters fundamental physics theories amid ongoing cosmic explorations.
New model revives Einstein's idea for universe's origin
Scientists from Spain and Italy have proposed a model that replaces cosmic inflation with gravitational waves as the key force in the universe's early formation. Published in Physical Review Research, the study suggests gravity and quantum mechanics alone can explain the cosmos's structure. This approach draws on a century-old concept linked to Albert Einstein's work.
