Astronomers have reported a bumper crop of new gravitational wave detections. The 35 new signals, comprising the third Gravitational-Wave Transient Catalog (GWTC-3), help scientists probe the depths ...

It’s tricky business detecting gravitational waves – these ripples in the very fabric of spacetime are often drowned out by background vibrations from earthquakes, traffic and other human activity.

A compact stellar corpse in our own galaxy has just delivered one of the strangest surprises in recent astrophysics: a vast, ...

New observations of a far-flung galaxy cluster have left a group of scientists stumped as they ponder whether they’ve discovered a new form of physics. In their new paper, researchers Tessa Vernstrom ...

This video explains overlapping waves on a string using concepts from AP Physics 1. We explore superposition, interference, and how wave pulses interact when they meet, with clear visuals and ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By ...

Researchers at the LIGO gravitational wave observatory used a new technique called frequency-dependent squeezing to boost weak signals above quantum noise. When you purchase through links on our site, ...

As the Olympics get going in earnest this week, not everyone's attention is focused on the host city, Paris. Surf fans are heading to Tahiti, which is half a world away in French Polynesia. Why? Well, ...
