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 ...

EPFL researchers have developed a method to calibrate electron spectrometers with extreme accuracy by linking microwave, ...

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.

New methods of detecting ultra-low frequency gravitational waves can be combined with other, less sensitive measurements to deliver fresh insights into the early development of our universe, according ...

Optical frequency combs are essentially high-tech "rulers" for measuring different colors of light; they're useful for making better atomic clocks and hunting for exoplanets, among other things. Now ...

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 ...
