New Method Uses Gravitational Waves to Improve Measurements of the Universe's Expansion Astronomers have long known that the universe is expanding, but the exact rate of expansion, measured by the Hubble constant, remains a mystery. Multiple methods used to calculate this constant have produced conflicting results, leading to the so-called 'Hubble tension.' Researchers from the University of Illinois and the University of Chicago have developed a new technique that uses gravitational waves—ripples in spacetime caused by black hole collisions—to measure the expansion rate. This approach refines earlier gravitational wave-based methods and promises more accurate measurements as detectors improve. Their findings show that gravitational waves could provide an independent way to measure the Hubble constant, potentially resolving the tension in current estimates. This research could offer insights into the universe's age and composition, and the team hopes to apply it to future data. The method relies on a new concept called the 'stochastic siren,' which uses the background gravitational wave hum from numerous black hole mergers, not detectable individually, to estimate cosmic expansion. This technique may help narrow the range of the Hubble constant and resolve the discrepancies in current cosmological models.

Gravitational Waves

Today marks the 10th anniversary of the announcement of the direct detection of gravitational waves by @ligo.org. In honor of that milestone, we've put together a collection of our coverage of gravitational-wave research through the years. #LIGO #gravitationalwaves #physics #astronomy

Today, 11 February, #GW stands for two things: #GravitationalWaves 〰️ and #Girls&Women ❤️.
We mark 10 years since the first GW detection announcement (11 Feb 2016) and the International Day of Women and Girls in Science.
Both began in 2015 (GW150914). ✨
