Scientists Uncover Secrets at Centre of Black Holes
Friday, April 25th, 2008
Scientists say they have moved one step closer to understanding the processes occurring in supermassive black holes. Black holes are thought to be the feature at the rotational centre of most galaxies. For the first time astronomers have observed a blazer in action – one of the most energetic objects in the universe that is fuelled by supermassive black holes. Periodically these black holes emit jets of high-energy plasma at almost the speed of light. The astronomers, based at Boston University and the University of Michigan (U-M), discovered that the jets were propelled by magnetic fields that were twisted by the gravity of the black hole and the materials falling into it. The sighting was made by a variety of telescopes aimed at the blazar BL Lacertae, about 950 million light-years away from Earth. Optical, X-ray and radio telescopes monitored the galaxy at different electromagnetic wavelengths periodically for several years. “What we’ve observed is the mechanism by which the acceleration of relativistic particles in the emanating jets occurs,” said Hugh Aller, a professor in the U-M Department of Astronomy. “Knowing that mechanism enhances our understanding of the physics that goes into the acceleration process.” Margo Aller, a research scientist and lecturer in the U-M Department of Astronomy, added: “This is the first observational evidence that really fits with the picture that the theoreticians have had. “The reason we have this evidence is a very fine sampling of a large number of instruments.” The discovery is published in the journal Nature.

I love all the jibe around black holes. I propose a simple explanation. Take the black holes each one of us has, namely our mouths. Stuff it full of matter such as food, and then be amazed as it is transformed (assimilated and metabolized) to another form of energy. Now that wasn’t so hard was it? Might save a lot of money in the process. Frankly, I think it would be more interesting if we solved some of our mysteries closer to home, namely crop circles.
