Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to physicists. Neutron star mergers are a treasure trove ...

The 2026 budget request states that NSF will operate only one of the two LIGO sites, drastically reducing its cosmic listening ability. Reading time 3 minutes Nearly 10 years ago, scientists observed ...
