Can we do away with the troublesome singularity at the heart of black holes? A new paper in JCAP reimagines these extreme objects in light of current knowledge. “Hic sunt leones,” remarks ...

According to Einstein’s theory of general relativity, if enough mass collapses under its own gravity, it forms a black hole with a central point known as the singularity. A singularity is a ...

That's what many physicists believe is happening with the black hole singularity. The infinitely small point might not physically exist, but general relativity can't quite grapple with the true ...

Once you form a black hole with an event horizon, all the matter inside gets crunched into a singularity. And since nothing can escape, you might think a black hole would remain a black hole forever.

Both of these approaches can replace the traditional singularity in the center of a black hole with something else. But when you replace the singularity, you usually also eliminate the event horizon.

What [does] it means for a black hole to spin? What is actually spinning? How can a singularity spin? Is there a "speed limit" to this spin rate and how does the spin affect the size of the event ...

Falling into a black hole may not be as final as it seems. Apply a quantum theory of gravity to these bizarre objects and the all-crushing singularity at their core disappears. In its place is ...

When a star collapses forming a black hole, a space-time singularity is created wherein the laws of Physics no longer work. In 1965 Sir Roger Penrose presented a theorem where he associated that ...

Black holes are regions of infinite density, known as a singularity. And according to mainstream physics, each of these cosmic matter munchers is fringed by an event horizon –- a boundary where ...
