Astronomers using the James Webb Space Telescope (JWST) keep finding the same impossible thing: ancient supermassive black holes; monsters millions of times the sun’s mass, existing when the cosmos ...

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all.

When Hurricane Helene tore into Florida's Gulf Coast on September 26, 2024, with 140 mph winds, its devastation rippled far ...

Astronomers have finally caught a spinning black hole in the act of twisting the fabric of spacetime itself. The discovery came from watching a distant star get torn apart, forming a glowing disk and ...

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 ...

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made ...

First direct evidence of black hole frame-dragging observed Spinning black hole seen twisting spacetime during stellar destruction Discovery confirms a 100-year-old prediction of general relativity ...

Einstein said a spinning mass should twist spacetime around it. For more than a century, that idea remained frustratingly hard to catch in the wild. Now, astronomers watching a star being ripped apart ...

An artist’s impression depicts the accretion disk surrounding a black hole, in which the inner region of the disk wobbles. In this context, the wobble refers to the orbit of material surrounding the ...

Scientists observing a dramatic cosmic outburst have confirmed a prediction first explored in Albert Einstein’s work on relativity more than a century ago. A global team detected the first clear signs ...
