But what exactly are white holes, and why have we never detected one? The idea of white holes challenges everything we know about gravity and the nature of space-time.

The James Webb Space Telescope has found perhaps its most profound discovery to date. The uncovered preferred direction for galaxies supports the idea that the universe was born in a black hole.

"This black hole could then grow and consume the entire planet, turning it into a black hole with the same mass as the ...

NASA finds supermassive black hole called ‘Space Jaws:’ Why it deserves sci-fi horror name A sneaky black hole was the source of a tidal disruption event that was so large and so bright that ...

Space & Spaceflight Black Holes Could Be Tunnels to White Holes, New Theory Suggests Black hole singularities might be the beginning rather than an end, new research suggests.

For years, scientists have theorized that some black holes could actually be wormholes, and a new study shows that this space-time mimicry could in fact be possible.

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 ...

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 ...

Instead, space and time transition into a new phase called a white hole -- a theoretical region of space thought to function in the opposite way to a black hole.

Supermassive black holes are seen as sources of wanton cosmic destruction, but there may be more to their powerful influence than first meets the eye.

Scientists discovered a distant black hole 300 million times the size of the sun. It's a portal back in time.
