What’s really inside a black hole? Long considered one of the greatest cosmic mysteries, black holes were first predicted in 1916 through Einstein’s theory of relativity. Yet it wasn’t until the 1960s ...

With the recent first light milestone for the Vera Rubin Observatory, it's only a matter of time before one of astronomy's ...

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

In a new paper, published in Physical Review D (full preprint here), my colleagues and I propose a striking alternative. Our calculations suggest the Big Bang was not the start of everything, but ...

The Black Hole Universe: New Model Suggests The Big Bang Was Not The Beginning Of Everything "We are not witnessing the birth of everything from nothing, but rather the continuation of a cosmic ...

The black hole universe also offers a new perspective on our place in the cosmos. In this framework, our entire observable universe lies inside the interior of a black hole formed in some larger ...

Black holes—areas of space where gravity is so strong that not even light can escape—have long been objects of fascination, with astrophysicists, theoretical physicists and others dedicating ...

While black holes are often described as sucking everything, including time, into a point of nothingness, in the paper, white holes are theorised to act in reverse, ejecting matter, energy and ...

New research suggests black holes may transition into ‘white holes’, ejecting matter and potentially even time back into the universe, defying our current understanding of these cosmic giants. The ...

Here’s how it works. Jets of plasma erupt from both sides of a supermassive black hole in a distant galaxy. (Image credit: NSF/AUI/NSF NRAO/Meyer at al. 2025) ...

Even more surprisingly, both the disk and black hole were rotating at a 90-degree angle relative to the rest of the galaxy, meaning both features are essentially "lying on their sides," NASA said.

Some scientists think black holes are back doors to other universes. If true, this theory could explain how all of the matter in our universe was created.
