My hunch is that black holes do exist, but I would like to read the article. Is it around on-line? Thanks, Joe --- On Sun, 9/27/09, Don J. Colton <djcolton@piol.com> wrote: From: Don J.

Colton" <djcolton@piol.com> To: "'Utah Astronomy'" <utah-astronomy@mailman.xmission.com> Subject: [Utah-astronomy] Perhaps Black Holes Do Not Exist Date: Thu, 24 Sep 2009 11:25:32 -0600 The October Scientific American argues that black stars more dense than neutron stars may form instead of black holes. Black holes are predicted by classical general relativity but do not take properly take into account quantum mechanics. A quantum effect called vacuum polarization may grow large enough to stop a hole forming and create a "black star" instead. Such a star would not have an event horizon but any energy emitted would be shifted far to the red and not show as visible light. A major problem with black holes is the loss of information that would occur violating a fundamental feature of quantum mechanics called unitarity. I have always been skeptical of singularities since in every other area of physics singularities mean a failure of the math or theory or both. When the theory predicts such things as infinite energy (the ultraviolet catastrophe) or singularities it usually means the theory needs to be modified. _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com ____________________________________________________________ Best Weight Loss Program - Click Here! http://thirdpartyoffers.juno.com/TGL2141/fc/BLSrjpTFoYcCfBKQy4ydOwf0CuJk4NEc MFnxQvkeHfBp4mOWw0ucUQKZ3BO/ _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com
