In simplest terms a black hole is an area of space that has so much mass concentrated in it that there is no way for nearby objects to escape its gravitational pull. To understand the magnitude of this gravitational pull we need to explore our best theory of gravity, at the present moment, Einstein’s general theory of relativity. His premise states that anything with mass will bend the fabric of space and time. The …showed first 75 words of 1296 total…

…showed last 75 words of 1296 total…tell us that Einstein’s theory of relativity is, for the most part, correct. Therefore when scientists apply these equations to cosmology, they can be confident that their calculations are correct. On a more direct level black can tell us the true size and mass of the universe. It is a little bit complex on this level, but black holes are important on many different standpoints and certainly deserve more study (http://www.singnet.com).
