Black holes, dark energy... and darkwing duck
What the above have in common? They are all fantasy. True, the first two are the result of a mathematical model of the universe. But is seems that math constructs beat observations, in the current scheme of things, hands down.NASA Satellite Captures Black Hole Birth GREENBELT, Md. (AP) -- The birth of a black hole has been captured for the first time, a NASA scientist said Monday. NASA's Swift orbiting observatory detected the gamma ray burst of the collision between two dense neutron stars about early Monday and pointed its visible light and X-ray telescopes at the collision about a minute later, said Neil Gehrels, lead scientist for the Swift mission. "The birth cry of a black hole is one way people like to put it," Gehrels said, adding the huge flash of gamma rays was "seen across the whole universe." "Birth cry"..., Oh, the sheer poetry of it! "Across the whole universe"... mc squared be damned! The satellite recorded the x-rays from the collision, but the visible light was too faint to be detected by the satellite. However, alerts sent to ground-based telescopes enabled them to view the afterglow of the collision, Gehrels said. Astronomers have theorized the collapse or collision of massive stars is what produces black holes - so dense not even light can escape - and that the resulting gravitational energy sends gamma rays shooting out across time and space. The collision matched what theorists had predicted would happen when two dying stars collide, Gehrels said, helping solve a "mystery that has been with us for 30 years." #1. So, which was it, x-rays or gamma rays? If the model predicts gamma rays and you get x-rays burst, the prediction does not pan out. #2. The stars in question have different red-shifts (I still have to verify this), that would place them so apart that it is not even funny, according our esteemed cosmologists take on the red shift. So, did they colide via some 'spooky mechanism at a distance'? It may be a considerable distance, I may add. #3. "the visible light was too faint to be detected by the satellite". But "black holes - so dense not even light can escape". OK, it may be just that the writer is too dense. Posted by: Sobiesky 2005-05-10 |
