General relativity is one of the most successful theories mankind has ever developed, but one of its predictions—the existence of gravity waves—has never been confirmed. Gravity waves are ...

LIGO confirmed the existence of gravitational waves in 2015, detecting one-time perturbations of spacetime from the merger of large black holes. There should be a background of gravitational waves ...

The gravitational wave background, a kind of cosmic noise that has long been theorized but never detected, is made up of ultra-low-frequency gravitational waves.

What occurs when two black holes, each greater than a hundred Suns, smash into each other in the shadows past our galaxy? In ...

Astronomers may be getting closer to discovering as-yet hidden cosmic secrets, such as the nature of dark matter and the presence of widespread distortions in space-time, researchers reported at ...

NANOGrav hears “hum” of gravitational wave background, louder than expected Exotic stars called millisecond pulsars serve as celestial metronomes. Jennifer Ouellette – Jun 28, 2023 8:00 pm | 46 ...

A team of astronomers have compiled 12.5 years of data from the Fermi Gammy-ray Space Telescope to form a gamma-ray pulsar timing array, a system of cosmic lighthouses that could help reveal ...

The hunt for elusive gravitational waves has a new target: singing cosmic superstrings that theoretically emit the long-sought waves as they vibrate. The superstrings are "so light that they can't ...
