So on the History channel, there was a special on quasars and black holes. So basically quasars are active galaxies millions of light years away from Earth. Since they are so far away, scientists have concluded that these galaxies are ancient. At the center of these galaxies are black holes. Black holes are a region where great amounts of compression has occurred. The bodies and matter in the region have collapsed under its own gravity. Black holes compact matter so densely, even light. The spinning action produces a "swirl of space" pulling gas streams in a spiral direction towards the hole. The gas streams collide as a result of the massive gravitational energy creating intense friction and heating the galaxy. This is what gives a quasar such luminous light. Astronomy is ver intriguing to me. But these black holes are some scary sights. I saw an example of one on the latest Star Wars movie that was released earlier this year. But nonetheless, they are still interesting to me. Some scientists are proposing an experiment where they can monitor minute black holes and observe how they form as well as disappear. They believe that this will reveal remarkable things about the universe. Black holes can expand great distances. There is some fear that these black holes may grow to swallow the entire Earth. But scientists state that the experiment will not put Earth in a catastrophic circumstance.
