There were apparently 1 nonsensical structures of space and time, spat 2 out when Albert Einstein's equations were taken to their extreme conclusion. Einstein's theory of relativity does lead us into very strange and unfamiliar 3 paths. Einstein himself didn't believe in black holes, but in our search to understand them, we might have found a clue to the biggest question of all, the very origin of the universe. It's like there is just a huge question mark in the sky where one of these things exists, they are the most mysterious objects in space, it's where the equations themselves break down. Black holes are so complex, so fantastical that even now we know they are real, they throw up more questions than answers, how can they exist? they simply don't make sense. A black hole represents a spot in space around which the gravity is so intense that nothing not even light can get away, it's a region bounded by something called the event horizon, within which all events are beyond the horizon of someone outside, meaning they can not see anything that's happening inside there, so it's region of space which no information can ever escape. Scientists think that these extraordinary monsters in space are created by the death of the most massive stars, rare stars whose cores are so huge that when they collapse 4, they don't turn into a pulsar, the collapse just keeps on going.
