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 ...

Space might seem calm when gazing up at the night sky, but invisible waves ripple continuously through the universe, bending space and time. These waves, known as gravitational waves, carry crucial ...

Until recently, gravitational waves could have been a figment of Einstein’s imagination. Before they were detected, these ripples in spacetime existed only in the physicist’s general theory of ...

A recent preprint claims that we may someday be able to create gravitational waves in a lab. Through the use of “twisted” light, we could create powerful, high-frequency waves in a controlled setting.

There’s a big debate in cosmology about how fast the universe is currently expanding. The collision of two neutron stars in 2017, seen in an artist's rendering, created both gravitational waves and ...

When two massive objects – like black holes or neutron stars – merge, they warp space and time. Mark Garlick/Science Photo Library Scientists first detected ripples in space known as gravitational ...

In a paper published in The Astrophysical Journal Letters, the international LIGO-Virgo-KAGRA Collaboration reports on the ...

The universe is expanding; we’ve had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate. It’s no small feat to measure the ...

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today. A new theory suggests gravitational waves ...

Learn about two black hole mergers in 2024 that experts revisited with new information from gravitational waves, confirming ...

FROnt Surface Type Irradiator, or FROSTI, will allow future detectors to run at higher laser powers, reducing noise and expanding capabilities ...
