    Black Holes

    Black Holes are, according to NASA (2014), "a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star's life. Some black holes are a result of dying stars. Because no light can escape, black holes are invisible." Black holes come in a number of sizes but according to NASA (2014), there 3 main ones. Primordial Black holes are the smallest which, " is as small as a single atom but with the mass of a large mountain." The next is a stellar or medium black hole which according to NASA (2014), "can be up to 20 times greater than the mass of the sun and can fit inside a ball with a diameter of about 10 miles. Dozens of stellar mass black holes may exist within the Milky Way galaxy." And lastly, the biggest are the supermassive black holes (NASA, 2014), "have masses greater than 1 ...
