Black Holes 2

Black Holes What are black holes? Black holes are the remains of a massive star that has collapsed and shrunk to a tiny point in space. They have all of the gravity of the star concentrated into a miniscule point many times smaller than the original. Black holes are difficult to see because they are spinning faster than the speed of light. This causes all light to be pulled to them leaving no refractions to …

…energy sources are also good clues. Astronomers have also located black holes by studying the speeds of swirling galaxies. If large objects are moving at very high speeds astronomers usually try to track their orbits and try to locate a central object that could be the source of the gravity. Astronomers believe there may be thousands of black holes and other mysteries of space, and they hope to learn more about them in the future.
