Within our galaxy alone there are millions upon millions of stars Within our universe there are millions upon millions of galaxies Humans have known the existance of stars since they have had eyes Although interpretations may have differed on what they were they were always thought of as white glowing specks in the sky but the mystery does not lie within what we can see but what we can not see There are billions of stars lighting the darkness of our universe but the question lies in what happens when one of these enormous lamps burns out Upon many speculations one of the most facinating is the black hole theory Not any star can become a Black Hole For instance the possibility of our sun becoming a black hole is highly unlikely simply because it is too small Only a very large star has the potential to become a black hole The definitions of black boles are somewhat sceptical Generally a black hole is an area of super-concentrated mass So concentrated that no object can escape its gravitational pull In other words once you get caught by its graviational pull you arent getting out again The velocity you need to break away from a graviational pull is called the escape velocity Roughly earths escape velocity is about 25000 MPH 112 kilometerssecond Earths mass is nothing compared to the mass of a star that has the potential to become a black hole A black hole has so much mass in such a small area that its escape velocity is greater than the speed of light So if were all living on earth and earth was a black hole we would need to go at the speed of light in order to get to the moon and not to mention a lot of milk so our bones
