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

But in contrast to black holes, gravastars are not expected to have any singularities and are thought to be thin spheres of matter whose stability is maintained by the dark energy contained within ...

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

It's what gives black holes their strong gravitational pull. And for decades, scientists thought singularities were all the same, so anything that passed the event horizon would be destroyed the ...

The center of a black hole is known as a singularity, a point of infinite density. This is where our current understanding of physics breaks down. Simulations show that the singularities quickly ...

Singularities within equations are common ... With the discovery of the pulsar, the idea of Black Holes being real objects began to take foot in the halls of universities and observatories ...

A decade after the discovery of the “amplituhedron,” physicists have excavated more of the timeless geometry underlying the ...

No one called these superdense curiosities black holes—they were referred to as frozen stars, dark stars, collapsed stars, or Schwarzschild singularities, after the German astronomer who solved ...

We demonstrate that if the production technologies, too, are frictionless, all workers will eventually be pulled into the most labor friendly sector (economic black hole). If, instead, they are ...

Physicists are working on the problem in the laboratory by creating acoustic black holes - singularities that are strong enough to trap sound, but not light. The mathematics behind acoustic black ...
