Black holes are for real. Yes you heard that right. The studies, all reported last month, suggest new ways to find black holes at the cores of galaxies and measure their mass. Supermassive black holes are the big brothers of stellar black holes, which typically weigh about 10 times the sun's mass. Imagine that.(actually how much is the sun's mass ?) Not all black holes hide behind dust. Some fuel quasars, the beacons of visible light that rank among the most brilliant objects in the cosmos. Black holes power quasars by converting gravitational energy--the energy gained as they suck in gas and dust--into radiation. The more a black hole eats, the more radiation it generates. These are some wicked black holes

    This is a very interesting topic, but one full of speculation. What is very important when reading and thinking about anything astrological is that all unmeasureable astronamy has to rely on mathematical presupositions. These presupositions basically dictate the outcome. For instance, Steven Hawking is an atheast and has spent his whole life trying to prove that God does not exist. the problem is, he has forgotten that his starting prsuposition was that God does not exist. the only reason his big bang theory kind of works (it has many many problems to this very day) is that he started from the presuposition that God does not exist, and therefore, earth could not possibly be close to the center of the universe. so he is trying to prove that God doesn't exist by starting a mathematical calculation that starts at the same point, hes been going in circles. There is another theary which sais God exists, it uses black holes in reverse to describe its own type of "big bang" and works out just fine. Black hole are very interesting but only serve to tell us that in reality we really don't know very much at all....
