General relativity may preserve habitable planets around white dwarfs
Reported by AI
A new study suggests that Einstein's general relativity could prevent tidal heating from destabilizing rocky planets in the tight habitable zones of white dwarfs. Researchers found that orbital precession caused by the theory's effects might decouple inner planets from larger companions, allowing life to persist for trillions of years. This challenges prior models that predicted runaway greenhouse effects on such worlds.
Twin black hole mergers test Einstein's general relativity
Reported by AI
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.
