By looking at radio waves and X-ray emissions, a team of physicists has found the supermassive black hole Sagittarius A* to be spinning— and altering space-time around it.

Researchers have found that the supermassive black hole in the center of our Milky Way galaxy, known as Sagittarius A*, is spinning so rapidly that it is altering the fabric of space-time around it.

A cosmic leviathan stirs across the great, quiet expanse of the early universe. About 12 billion years old, a supermassive ...

Space-time curvature around a black hole might sound abstract, but understanding it is crucial to grasp the nature of these ...

In a recently published paper in Physical Review Letters, scientists propose a comprehensive theoretical framework indicating ...

A defining feature of a black hole is its event horizon, a one-way membrane in space-time. Objects – including light – that cross the event horizon can never leave due to the black hole’s incredibly ...

A black hole is a terrifying concept, but the mysterious nexus of physics and space-time isn’t always gobbling up matter. While famous for devouring anything and everything in its gravitational ...

“This rare event provides an opportunity for astronomers to observe a black hole’s behavior in real time, using X-ray space telescopes XMM-Newton and NASA’s NICER, Chandra and Swift,” said Dr. Lorena ...

Crucially, this bounce occurs entirely within the framework of general relativity, which applies on large scales such as ...

Two of the universe’s most extreme objects—black holes and neutron stars—can spiral into cosmic collisions that crack crusts, ...
