Scientists have detected a strange new type of high-frequency wave on the sun's surface, and the waves are moving three times faster than scientists thought was possible. The acoustic waves, called ...

These acoustic waves, which astronomers spotted within a dataset spanning 25 years of observations by both space and ground-based observatories, travel three times faster than predicted by current ...

In September 2015, a vibration lasting just one-fifth of a second changed the history of physics. It was the first direct detection of gravitational waves — perturbations in the geometry of space-time ...

Until recently, gravitational waves could have been a figment of Einstein’s imagination. Before they were detected, these ripples in spacetime existed only in the physicist’s general theory of ...
