If it’s true, this work could have ramifications for some of the biggest mysteries of the universe, including learning where ...

University of Colorado Boulder astrophysicist Jeremy Darling is pursuing a new way of measuring the universe's gravitational wave background—the constant flow of waves that churn through the ...

There’s a third way to measure the Hubble constant that uses collisions of extremely massive objects in space—such as black holes and/or neutron stars—as “standard sirens.” These collisions can ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how ...

It tends to move the object towards the mass. The strength of this force depends on the gravitational constant. Denoted by a ‘G’, it is a fundamental physical constant. It was first accurately ...

In June, researchers from the North American Nanohertz Observatory for Gravitational Waves, or NANOGrav, published the results of 15 years of observations, finding evidence for a constant, ...

There was a secret inside the envelope in the hands of Stephan Schlamminger, one of the world’s leading experts in experimental tests of gravity. He appeared to be on the verge of opening the ...

2: They use changes to the cosmic microwave background (CMB) – radiation leftover from the Big Bang event – to estimate the Hubble constant. 3: They use gravitational waves, ripples in ...

Stocktrek via Getty Images The universe is filled with a constant hum of gravitational waves, according to new observations from separate teams of scientists around the world. Gravitational waves ...

Astronomers and astrophysicists at five different pulsar timing array collaborations today announced data that strongly suggests the presence of a gravitational wave background: a constant murmur ...
