A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

An international collaboration of astrophysicists that includes researchers from Yale has created and tested a detection system that uses gravitational waves to map out the locations of merging black ...

Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

Scientists have named two systems of colliding supermassive black holes after Lord of the Rings locations, Gondor and Rohan.

The total energy of the ball consists of its potential energy (related to position) plus its kinetic energy (related to motion). To zero out both components, you would have to give a precise value to ...

At the heart of flight lies Newton's third law: for every action, there is an equal and opposite reaction. This principle explains how an airplane wing generates lift. When an airplane moves forward, ...

Astronomers at the University of Alabama in Huntsville may have found the closest evidence yet of a hidden clump of dark matter near the Sun. Led by astrophysicist Sukanya Chakrabarti, the research ...

On January 14, 2025, a pair of black holes with nearly identical masses crashed together roughly 1.2 billion light-years away, producing a gravitational wave signal so clean and powerful that it ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

Webb telescope data confirm a supermassive black hole fleeing its galaxy, carving a 200,000 light-year wake of new stars.

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to ...

Bobsledders rely a lot on specialized equipment to perform well and stay safe during the "Formula 1 of ice.” Here’s a quick guide.
