Researchers spotted a second distant star orbiting a well-known black hole and its stellar companion in a never-before-seen ...

Black hole formation could be a little Big Bang in reverse, coupling the matter of a dying star with dark energy, the ...

In particular, the center of a black hole is predicted to be a point of infinitely high density, called a singularity, where all the mass of the black hole is concentrated, but fundamental physics ...

If true, this theory could explain how all of the matter in our universe was created.

New research suggests black holes are unstable, challenging Einstein's theory of general relativity and the Kerr solution.

Black holes have two parts. There is the event horizon, which you can think of as the surface, though it’s simply the point where the gravity gets too strong for anything to escape. And then, at the ...

At the center of every black hole is a point of infinite density, called a singularity. It's what gives black holes their strong gravitational pull. And for decades, scientists thought ...

Prof Stephen Hawking has died aged 76. The Cambridge theoretical physicist was one of the best-known scientists in the world, but what about his discoveries? His fame among researchers was founded ...

Astronomers have accidentally discovered the first-known "black hole triple" system, containing a dark void orbited by two stars. The unique configuration of this triad hints that the black hole ...
