Astrophysicists have proposed a new way to measure cosmic expansion by analyzing the gravitational-wave background—the faint spacetime “hum” from countless distant black hole mergers.
Known as the stochastic siren method, this approach offers an independent tool to address the Hubble tension. As detection technology advances, it could refine estimates of the universe’s size, age, and the nature of dark energy.
