Black Holes - schoolphysics
... How we can ‘see’ a black hole We can’t actually observe a black hole directly but we can ‘see’ black holes because of its effect on its surroundings. The material close to the event horizon of a black hole forms a disc. This disc is compressed and the motion of the gas within the disc means that the ...
