Simply put, a black hole is a region of space-time where gravity is so strong that nothing can escape from it. This includes light, which travels at the cosmic speed limit of 186,000 miles per second.

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 ...

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 ...

In the world of black holes, there are generally three size categories: stellar-mass black holes (about five to 50 times the mass of the sun), supermassive black holes (millions to billions of times ...

The younger black hole, the product of a cataclysmic cosmic event known as a black hole merger, was first spotted in 2019. Now, about 6 years later, a team of international researchers led by the ...

Scientists say they detected the largest-ever merger of two black holes, forming one that is 225 times the mass of the sun, adding that the new discovery "pushes the limits of" how astronomers ...

A tiny fraction of known black holes emit X-ray signals that resemble a human "heartbeat." Now, new research may finally explain the strange phenomenon. Stars that wander too close to supermassive ...

Astronomers have detected the signal of a colossal black hole in deep space that likely formed when two already-large black holes crashed into each other billions of light-years away. The result is a ...

Scientists have for the first time ever succeeded in getting some data on a newborn black hole that was sent hurtling off into space after two larger ones collided together and "birthed" it. The ...
