Black holes are the strangest things that we know of in the universe precisely because we know nothing about them. What we do know is based on theories which scientists are working on to uncover. The death of a star substantially large enough will collapse in on itself after a supernova with such force it will form a black hole… we think.
This documentary interviews scientists from around the world to help gather what we think we know about black holes. It’s a strange field of science where quite literally finding nothing is better than finding something and where the fundamental laws of science break down into a blur of bizarreness.
