The spins of some early galaxies could be a clue that the entire observable universe exists within a black hole—except, that ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

The black hole pressures—P S, the outward pressure keeping it inflated from the negative scalar curvature, and P M the inward pressure from self-gravity trying to compress it—are gravitational ...

This galaxy's central black hole appears to be a "messy eater" as its interstellar scraps are strewn into space.

Whether a galactic environment has the right conditions for habitable planets to form could depend on how the black hole in ...

In a new book release, two scientists combine forces to explain the discoveries, developments and theories made in the realm ...

One of the most powerful objects in the universe is a radio quasar—a spinning black hole spraying out highly energetic ...

This might change our understanding of the universe. Scientists have developed a theory that eliminates the problem of ...

A new model has been proposed that challenges the long-standing belief that black holes contain a singularity, a region where space and time break down. This theory suggests that black holes could ...

Whether a galactic environment has the right conditions for habitable planets to form could depend on how the black hole in ...

The James Webb Space Telescope has given us a view of the earliest moments of galaxy formation in the universe. It's also ...

First, the outer boundary of these cosmic titans is a one-way light-trapping surface called an event horizon, the point at which a black hole's gravity is so powerful that not even light can escape.
