PITTSBURGH (KDKA) -- We have another question to answer, and this one has to deal with some very interesting clouds. Ray C. took a picture just outside of Uniontown, Pennsylvania, where you can see ...

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 cosmos, ...

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two ...

Gravity waves are a type of cloud pattern that have little to do with gravity and more to do with the waves. Think of a rock being thrown in a lake or pond and the ripples it creates. As the ripples ...

The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

Gravitational wave astronomy is starting to do more than confirm Einstein’s equations. It is turning into a precision tool for mapping the invisible, with theorists now arguing that ripples in ...

On May 21, 2019, the mass of eight suns disappeared. In a universe like ours, in which mass and energy are conserved, mass cannot disappear without consequences: and so it went that, as two distant ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By transferring minute amounts of energy between light and gravity, the interaction ...

Until recently, gravitational waves could have been a figment of Einstein’s imagination. Before they were detected, these ripples in spacetime existed only in the physicist’s general theory of ...

Decades ago physicists realized that gravitational waves are no mere passing phenomenon. Instead those ripples in space should leave behind permanent marks: a fixed distortion in their wake. So far ...

The gravitational wave background has probably been detected using a pulsar timing array. A few weeks ago a large team of gravitational wave astronomers announced something pretty wild - pervasive ...
