Gravitational waves may leave a permanent timing gap in light, revealing how gravity preserves information through a memory ...

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of ...

Should this gravitational wave even be possible?

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 ...

Could gravitational waves be used someday to probe distant matter in the universe? Through a theoretical physics calculation, researchers from Case Western Reserve University suggest that they could.

A new way to measure the cosmic expansion rate could help resolve a long-standing cosmological crisis. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

Caught in a fatal inward spiral, a neutron star met its end when a black hole swallowed it whole. Gravitational ripples from that collision spread outward through the cosmos, eventually reaching Earth ...

The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

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 ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

When a gravitational wave passes through a location in space, it causes an expansion and a compression at alternate times in alternate directions, causing laser arm-lengths to change in mutually ...

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is dedicated to detecting gravitational waves scattered across the universe in ancient cosmic events. Science correspondent Nell ...
