The observed near flatness of galactic rotation curves has long been interpreted as evidence for large amounts of non-baryonic dark matter. Here we show that this phenom ...

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

Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe's gravitational wave background.

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, ...

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

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 ...

Our understanding of the universe may be completely wrong.

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 ...

You can't see or feel it, but everything around you — including your own body — is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our ...

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 ...
