ok stay where you are we'll talk more in a moment first we're going to take more of a look at what black holes actually ah and why people say fascinated by them. black holes they're like cosmic vacuum cleaner sucking up anything that comes too close and the matter that crosses the so-called event horizon is then gone forever. black holes are created when dying stars collapse in on themselves or when two stars collide and their masses merge. the gravitational forces become so massive that the matter is squeezed into a single point called the singularity. black hole start small but as they suck up more and more material in their path they can begin to grow and eventually become super massive black holes like the one of the center of our galaxy the milky way. with the gravitational pull stronger than four million stars similar to our sun. until now astronomers had been unable to see the milky way central
