Cosmic maps appear consistent with the proposal that black holes could turn one 'dark' substance into the other.

The oldest and most distant black hole known to scientists dates back 13.3 billion years ago, when our universe was still in its teething stage.

Supermassive black holes exist within galaxies, significantly heavier than normal black holes, requiring advanced detectors like LISA for direct observation.

Everything is unusual about this galaxy. Not only does it look very strange, but it also has this supermassive black hole that's pulling a lot of material in.

Black holes could be the key to a quantum theory of gravity, providing a deeper understanding of how reality, space, and time works. They are regions of space from which even light can't escape, and have fascinated physicists since their theoretical predictions, which date back to the early 20th century. The existence of black holes forces physicists to think about both quantum theory and general relativity together, highlighting the need for a unifying theory or quantum gravity.
