On Thursday, June 28, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) revealed the detection of low-frequency gravitational waves, a historic breakthrough that ...

Researchers at the Niels Bohr Institute, University of Copenhagen, have developed a tunable system that paves the way for ...

The universe is continuously rippling with gravitational waves, a 15-year survey has reported. Using pulsars as distant beacons and radio telescopes to plumb the galaxy, a massive collaboration of ...

Cosmic lighthouses as gravitational wave detectors . To detect the gravitational wave background, astronomers studied fast-spinning stars called millisecond pulsars, which are dead stars that spin ...

Today, a humongous team of astronomers called the NANOGrav Collaboration announced something remarkable: the first evidence for a background hum of gravitational waves that permeates our universe ...

The frequency and intensity of past cyclones are determined by geologically dating and topographically surveying these features, then running numerical models that estimate surge and wave heights ...

A 0.5 Hz ultrasound frequency has a wavelength of over 600 microns. Human cells size from a few microns up to about 150 microns, all which are too small to exhibit internal resonance with a sound ...

Strange waves rippled around the world, and nobody knows why. Instruments picked up the seismic waves more than 10,000 miles away—but bizarrely, nobody felt them.
