A soaring cosmic symphony surrounds us; its notes emerge from massive celestial objects crashing together hundreds of millions or even billions of light-years away. But scientists have only tuned into ...

The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many ...

For just one-tenth of a second in May 2019, the universe delivered a signal that did not fit the usual script. LIGO and Virgo ...

In a groundbreaking discovery, the LIGO-Virgo-KAGRA collaboration detected the loudest gravitational wave ever observed, confirming Stephen Hawking’s area theorem on black holes. The event, GW250114, ...

In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the ...

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 ...

No space-based gravitational wave observatory exists…yet. But that hasn’t stopped a team of astronomers from demonstrating how the gravitational universe might look, using simulated data to create a ...

When astronomers detected the first long-predicted gravitational waves in 2015, it opened a whole new window into the universe. Before that, astronomy depended on observations of light in all its ...

One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space. So far, ...

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 ...
