Gravitational Waves
Strongest Black Hole Collision Detected
Riportato dall'IA
Astronomers detected the strongest black hole collision yet on September 11, 2025, resonating with Einstein's predictions. The event involved massive black holes merging, producing significant gravitational waves. This finding was published in a leading science journal, advancing astrophysics.
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.
Astronomers propose detecting gravitational wave beats via pulsars
Researchers at Hirosaki University have suggested a method to identify the source of ultra-low-frequency gravitational waves by looking for 'beat' patterns in pulsar signals. This approach could distinguish between waves from cosmic inflation and those from supermassive black hole binaries. The proposal builds on 2023 evidence from pulsar timing arrays that falls short of full confirmation.
