To destroy enough matter to explain the Hubble tension, black holes would have to merge at an unrealistic rate.

This new theory proposes that black holes could actually be tiny "bubbles". This involves the conversion of matter into dark ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can ...

The deepest mysteries of the universe often begin with the biggest questions. Few are more puzzling than the birth of ...

Dark matter is one of the biggest puzzles in science. Although it makes up about 85 percent of all matter in the universe, it ...

The newly confirmed supermassive black hole at the heart of CAPERS-LRD-z9 is known as an active galactic nucleus (AGN), the ...

“The gas spans the entire width of the system and was likely shocked and compressed at the collision site,” they and their colleagues said in a study soon to be published in the Astrophysical Journal ...

Calculations suggest stars that are very viscous could reflect gravitational waves and produce signals very similar to those ...

Astronomers using AI have captured a once-in-a-lifetime cosmic event: a massive star’s violent death triggered by its black ...

Because of this, we expect that most, if not all, black holes will be spinning very fast. It’s an odd concept because black holes don’t have a physical surface that can spin.

Black holes are some of the most mysterious objects in the Universe – a reputation not helped by the difficulty of studying ...
