1.3 billion years ago, two orbiting massive black holes, circling each other at 250 times a second, collided in a violent, ...

EVANSTON, Ill. (CBS) -- A Northwestern University astrophysicist is part of an international team of scientists creating a gravitational wave detector system that will eventually be launched into ...

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all.

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

Scott Detrow talks to Lulu Miller, the host of Radiolab's Terrestrials podcast, about her conversation with the scientist Wanda Diaz-Merced, who studies gravitational waves that ripple through ...

A new effort to map the rumblings in spacetime caused by enormous black hole collisions paints a surprisingly loud and lopsided picture of the universe. When you purchase through links on our site, we ...

A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, ...

Gravitational waves are made by colliding neutron stars, and could explain essential . . . nutrients. Our bodies rely on some “heavy elements” that may be, at least partly, from neutron stars. It’s ...

Our understanding of the universe may be completely wrong.

One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space. So far, ...

Ripples in space-time point to the merger of a neutron star with another mystery object. The object, which falls right within the mass-gap range, sheds light on a long-sought, murky realm. When you ...
