Hubble Constant Puzzle Deepens as Supernova and CMB Measurements Clash
Astronomers are testing a new way to measure the universe’s expansion rate using the gravitational-wave background detected by NANOGrav. By treating the cosmic hum from merging supermassive black holes as a statistical “stochastic siren,” researchers hope to calculate the Hubble constant and help resolve the long-standing Hubble tension betwe...

Scientists Identify Rare Black Hole Merger in the Early Universe Using Gravitational Mapping
Astronomers have identified two merging supermassive black hole systems named Gondor and Rohan using a new method combining quasars and gravitational wave background signals. The discovery offers a fresh way to map black hole mergers and understand galaxy evolution and cosmic gravitational waves in a clearer and more systematic manner.

Scientists Say Universe Has A "Background Hum", It Sounds Like...
Astronomers across the world announced on Thursday that they have found the first evidence of a long-theorised form of gravitational waves that create a "background hum" rumbling throughout the universe.
