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.

Ever wondered what happens when the most extreme space objects collide? Prepare to witness cosmic chaos where white dwarfs, neutron stars, and black holes crash into each other, releasing unimaginable ...

A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?

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.

A low-mass star races through the Milky Way at over a million miles per hour, a journey that began with either the supernova explosion of a vampire star or an encounter with black holes.

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.

The secret recipe of black holes: Study finds they can 'cook' their own meals in space A self-sustaining cycle ensures the cosmic juggernauts are constantly fueled with a continuous supply of ...

Dependent on polarization, this optical device can either absorb or reject light almost entirely, analogous to the behavior of a gravitational black or white hole in space.

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.
