A research team at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) has shown that it is possible to manipulate photons so that they can collide, interacting in new ways as ...

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.

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 ...

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 ...

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves ...

Ten years ago, scientists heard the universe rumble for the first time. That first discovery of gravitational waves proved a key prediction from Albert Einstein's theory of general relativity and ...

On Sept. 14, 2015 astronomers “heard” two black holes crashing into each other at close to the speed of light. This discovery was a watershed moment in physics and astrophysics, heralding an entirely ...

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 ...

Now, in the journal Physical Review Letters, researchers say their ability to analyze gravitational waves has improved so much over the past decade that they were recently able to verify a key idea ...
