Black holes, which are only theoretical but are believed to exist by nearly all astronomers, come in many sizes. Supermassive black holes are thought to reside at the centers of most or all galaxies. Less massive objects, called stellar black holes, seem to be distributed throughout galaxies like our own Milky Way. They are formed when massive stars exhaust their fuel supplies and explode their outer shell of gas in an event called a supernova. The remaining bulk, still several times more massive than the Sun, collapses into a black hole. A spinning black hole modifies the fabric of space-time near it. The spinning allows matter to orbit at a closer distance than if it were not spinning, and the closer matter can get, the faster it can orbit. Black holes are a great danger to almost everything. If a black hole were to come close to our galaxy, planet earth could not escape the powerful gravity and earth would be vacuumed or sucked right into the void of the black hole not only ending all life but completely obliterating the planet and the entire human race would cease to exist...which by my calculations would not be fun. .....as usual, just my thoughts. .....Johnny M.
