Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

Converting wave motion into electricity holds enormous potential as a renewable energy source, but a lack of standardized prototyping is holding back technological development. A research team led by ...

Astrophysicists propose a new “stochastic siren” method using the gravitational-wave background from black hole mergers to measure the Hubble constant and address the Hubble tension ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Astrophysicists from the University of Illinois and the University of Chicago have developed an innovative method to measure the Hubble constant -- the rate at which the Universe is expanding -- using ...
