From: Osher Doctorow on 21 May 2010 02:08 From Osher Doctorow In searching for Quantum Gravity and/or Unification of Interactions/ Forces, physicists are now tending toward the Quantum rather than the GR explanation of those searches or their goals, and a new paper by Jong-Ping Hsu of U. Mass Dartmouth USA is no exception: 1) "Yang-Mills gravity in flat space-time, II. Gravitational radiations and Lee-Yang force for accelerated cosmic expansion," arXiv: 1005.3250v1 [gr-qc] 18 May 2010, . The keywords "Yang-Mills gravity" bring up 67 papers in arXiv, including 6 in 2010. Hsu has published papers in at least 2 books by World Scientific (2006 and 2007) and papers in Phys. Lett. A97 2005, Nuovo Cimento 91B (1986), etc The paper is especially interesting because it explains accelerated cosmic expansion in the latest era without GR, and because it clarifies exactly how Yang-Mills Gravity differs from GR including the former involving flat rather than curved space-time, as well as being a masterpiece of organization and discrimination in the sense of comparing points of differences between YM and GR. I do have a criticism of the Quantum Theory basis of Yang-Mills Theory, since Quantum Theory in my view is a distortion of the real or physical Universe based on its extreme microscopic "distance" from the human level observer, just as GR has an extreme macroscopic "distance" from the human level observer. But Yang-Mills Theory does seem to be the best of the distorted theories up to now, and is a gauge theory. I will try to discuss the paper of Hsu in more detail later. Osher Doctorow |
