Illinois and UChicago Physicists Develop a New Method for Measuring Cosmic Expansion

A team of astrophysicists, cosmologists, and physicists has developed a novel way to compute the Hubble constant using gravitational waves. As our capability to observe gravitational waves improves in the future, this new method could be used to make even more accurate measurements of the Hubble constant, bringing scientists closer to resolving the Hubble tension.

Scientists are also examining other explanations, including early dark energy, exotic dark sector interactions, and possible modifications to gravity.
