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 ...

Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

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

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 ...

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, ...

On May 24, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) began an 18-month campaign to detect the most distant collisions between black holes and neutron stars ever ...

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 ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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 ...

Black holes are not cosmic vacuum cleaners. They are among the universe’s most extreme objects - and come in different sizes.

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 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 ...
