Hubble Constant Puzzle Deepens as Supernova and CMB Measurements Clash
- Wednesday March 4, 2026
- Written by Gadgets 360 Staff
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
- Monday February 16, 2026
- Written by Gadgets 360 Staff
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.
