For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

In one of the biggest discoveries in the history of space science, scientists have directly detected gravitational waves, the ripples in space-time predicted by Albert Einstein’s famous theory of ...

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 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, ...

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 ...

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

Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, known as quantum foam. It was a state where spacetime was unstable, and ...

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 tiny fraction of a second following the Big Bang, the universe allegedly experienced the most inflationary period it has ever known. During this inflationary era, space expanded faster than the ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...
