A controversial theory suggests the observable universe is the result of matter rebounding after the collapse of a black hole ...

The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

When two enormous black holes collide in deep space, they send shockwaves rippling across the universe. These shockwaves, called gravitational waves, bend and stretch the fabric of space itself.

Black holes, when they're just lurking around in space, are very difficult to spot, especially in other galaxies. They don't emit any radiation we can currently detect, and that's our main tool ...

A star met a violent end in a galaxy far, far away — about 600 million light-years from Earth. It wandered too close to a black hole and was ripped apart in a bright burst of light.

NASA's X-ray space telescope Chandra spotted the cosmic collision from the supermassive black hole at the heart of the galaxy Centaurus A.

Findings could imply that the Big Bang would no longer be an isolated event and suggest that every black hole in our universe ...

Crucially, this bounce occurs entirely within the framework of general relativity, which applies on large scales such as ...

The James Webb Space Telescope (JWST), launched in 2021, is currently the most powerful space observatory ever built.

Whatever its origin, this rogue black hole may not remain isolated forever. A black hole merger that could release these powerful gravitational waves that Yao mentioned could one day be detected by ...

Using NASA's Chandra X-ray telescope, astronomers witnessed a massive black hole jet slam into an unknown object in space.
