In 2023, physicists were awed to find nearly imperceptible ripples in the fabric of space and time — united as an entity known as spacetime. They were ripples discovered in association with ...

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.

Researchers report their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits.

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency bands for mobile communications, Wi-Fi, and GPS in smartphones. Physicists ...

The very fabric of the universe is ringing with gravitational waves from its earliest epoch, and researchers have finally "heard" this cosmic symphony. On Thursday, June 28, the North American ...

The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one.

Giant ripples in the fabric of space and time, light-years in scale, have been discovered for the first time, according to new research announced by astronomers. Gravitational waves of this scale are ...
