A newly merged black hole does not become quiet at once. It vibrates, sheds energy through gravitational waves and produces a ...

The universe is expanding; we’ve had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate. It’s no small feat to measure the ...

For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at Earth from a cataclysmic event in the distant universe. This confirms a major ...

Dark matter is thought to make up most of the matter in the universe, but the only way it interacts with its surroundings is through gravity. If two colliding black holes spiral through a dense region ...

Starting with the direct detection of gravitational waves in 2015, scientists have relied on a bit of a kludge: they can only detect those waves that match theoretical predictions, which is rather the ...

Global climate models capture many of the processes that shape Earth's weather and climate. Based on physics, chemistry, fluid motion and observed data, hundreds of these models agree that more carbon ...

Two colossal black holes among the most massive ever seen collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory.

PITTSBURGH (KDKA) -- We have another question to answer, and this one has to deal with some very interesting clouds. Ray C. took a picture just outside of Uniontown, Pennsylvania, where you can see ...

These are the questions that Dr. Nergis Mavalvala asks about the universe. It’s not the meaning-of-life stuff in the traditional sense, but more of how everything around us came to be. These are the ...

Fuzziness may rule the quantum realm, but it can be manipulated to our advantage. When two black holes spiral inward and collide, they shake the very fabric of space, producing ripples in space-time ...

The Laser Interferometer Gravitational-Wave Observatory, or LIGO, has already won its researchers a Nobel Prize — and now artificial intelligence is poised to take LIGO’s search for cosmic collisions ...

General relativity describes gravity not as a force but as the curvature of spacetime produced by mass and energy. Matter tells spacetime how to curve, and this curved geometry guides the motion of ...
