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.

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 ...

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.

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

How exactly does the country "move on" when a sizable slice of its elite class appears to regard liberal democracy as more an anachronism than a governing philosophy?

Real-world optimization problems often require an external “modeling engine” that computes fitnesses or data that are then input to an objective function. These programs often have much longer ...

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 CuriousKidsUS@theconversation.com. Can we generate a way to interact with dark ...

In my January 23, 2026, “The Universe” column, I wrote about some of the biggest bangs the universe has to offer: exploding stars, hiccupping magnetars, stellar disruptions and colliding black holes.
