"This tells us that objects like white dwarfs may be able to live very close to an event horizon for a relatively extended period of time." When you purchase through links on our site, we may earn an ...

"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

A new study suggests that a black hole singularity—where time and matter are condensed into infinitely small space—could be a transition to a beginning. This beginning is a white hole—a theoretical ...

Here’s what you’ll learn when you read this story: Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their ...

Science fiction is full of amazing space phenomena. Some of those phenomena have gone from theory to reality — like black holes and pulsars. But what about wormholes? These portals through space are ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Our understanding of black holes, time and the mysterious dark energy that dominates the universe could be revolutionised, as new University of Sheffield research helps unravel the mysteries of the ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

Black holes are well known for swallowing everything around them, which is probably why they get talked about so often. On the flip side, white holes are their mysterious opposite. These theoretical ...

Astronomers have discovered the oldest and most distant black hole — a behemoth that likely formed at the dawn of the universe, more than 13 billion years ago. The black hole lies at the center of a ...
