Gravitational wave astronomy is starting to do more than confirm Einstein’s equations. It is turning into a precision tool ...

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 ...

The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

Researchers have found the first direct evidence of a “background” of gravitational waves in the universe — a sign that gravitational waves from slowly merging pairs of supermassive black holes, or ...

Physics fans are a lot like surfers. Both think waves are really fun. For surfers, it’s all about having a good time. For physicists, it’s about understanding some of nature’s most important physical ...

Eight days ago, it rained over the western Pacific Ocean near Japan. There was nothing especially remarkable about this rain event, yet it made big waves twice. First, it disturbed the atmosphere in ...
