What is a Black Hole?
Black holes are some of the strangest object in space due to the effects they have on absolutely everything, even light!
A black hole is an area in space with extremely strong gravity. The gravity is so strong around black holes that once you get within a distance called the 'event horizon' of them, nothing can escape and everything is trapped within the black hole. This includes matter which makes up the world around us as well as light - and if light can't escape, as far as we know nothing can!
