Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

A new study has been accepted by the Journal of Cosmology and Astroparticle Physics that proposes two new models of black ...

As noted, the concept of black holes isn't new — scientists first theorized their existence in the early 20th century, according to the National Air and Space Museum.

Supernova concept challenged. The black hole’s apparent gravitational hold on an object so far away raises questions about its origins. Black holes are thought to form from the violent ...

Just three numbers—that’s all it takes to completely, unequivocally, 100 percent describe a black hole in general relativity. If I tell you the mass, electric charge, and spin (i.e., angular ...

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 ...

What is a black hole? A philosopher shows that physicists use different definitions of the concept, depending on their own particular fields of interest. A black hole is conventionally thought of ...

Black holes — regions of space-time with extreme curvature — first arose as a concept from solutions to Einstein's field equations suggested by German physicist and astronomer Karl ...

The type of black hole that’s sitting in the center of a galaxy is different. This is a supermassive black hole, or SMBH, and — as its name implies — it’s much heftier.

But isolated black holes are more elusive still. As a new study states: "Isolated BHs are extremely difficult to detect directly. They emit no light of their own, and the accretion rate from the ...

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 ...

This black hole image uses the same concept, converting the energy from a black hole that can be picked up at a massive distance using an ingenious planet-sized telescope into something our dumb ...
