Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

“Gravitational waves are really, really hard to detect,” Hogan says. It took decades of work before LIGO spotted its first swells, and the same is true of the pulsar timing technique.

Scientists are using pulsars to detect the gravitational wave 'hum' created from supermassive black hole mergers. Credit: ...

The achievement only made the direct detection of gravitational waves all the more alluring. But the task was daunting. Calculations show that as a gravitational wave ripples through space, ...

Predicted by Einstein and dismissed as undetectable, gravitational waves were finally heard in 2016. Now, with observatories ...

Detecting gravitational waves requires measuring the length of the laser to precise measurements: equivalent to measuring the distance to the nearest star, around four light years away, ...

But gravitational waves were not detected definitively until 2015, at the Laser Interferometer Gravitational-Wave Observatory (LIGO) — two facilities located in Washington state and Louisiana ...

These waves, known as gravitational waves, carry crucial clues about cosmic events. Scientists from the University of Colorado Boulder are taking a fresh approach to detecting these elusive signals.

Gravitational waves are very subtle. It takes extremely sensitive, precise instrumentation to detect the ripples that stretch and compress spacetime, a combination of time and three-dimensional space.

Thanks to LIGO (the Laser Interferometer Gravitational-Wave Observatory), which observes ripples in spacetime caused by cosmic events, we know that it’s possible to detect gravitational waves ...
