A LONG TIME ago, in a galaxy far, far away—somewhere in the general direction of the constellation of Leo—two black holes ...

Last month, OpenAI announced that its latest version of ChatGPT had solved a major math problem, one that had stumped experts ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

The World Health Organization has declared that an outbreak of Ebola in Central Africa is a public health emergency. Health officials are racing to trace contacts as the count of suspected cases rises ...

The Big Bang is often described as the moment everything began — a point of infinite density where the laws of physics broke down. But what if that picture is incomplete? A new study proposes a ...

General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from ...

As the war with Iran nears its one-month mark on March 28, complex escalation dynamics continue to drive the conflict. Iran’s escalation strategy centers on unrestrained retaliation in response to U.S ...

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the universe. For Joseph Farah, a fifth-year graduate student at UC Santa Barbara ...

When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. These distortions travel far out into the universe, but by the time they reach Earth, they have ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

According to @ai_darpa, an advanced AI-generated visualization demonstrates how mass curves spacetime, enabling smaller objects to naturally orbit within gravity wells created by heavier bodies. This ...
