<p>You do get the torsion 1-form by locally gauging only T4, because the tetrad is the torsion 1-form. The torsion 2-form is what gives the gap in the parallelogram. It is what gives the contortion tensor addition to the Levi-Civita connection. Remember torsion gaps are translational defects. Curvature is a disclination defect - i.e. change in orientation of a vector around a small parallelogram - that won't close if there is a curl in the torsion 1-form.<br /><br />torsion gap 2-form = D(tetrad...Jack SarfattiSat, 01 Jan 2011 01:42:54 +0100Einstein Curvature Gravity as a Spin 1 Yang-Mills Torsion Field

Henry Hudson, according to Catskill Hudson Valley legend met “little people” on top of a mountain who said they came to Earth every twenty years. Washington Irving, who knew the Henry Hudson story, has Rip Van Winkle “sleep” for twenty years. Allegedly this story was based on a real man who reappeared after twenty years after a hike to that same Catskill Mountain. Thousands of people allegedly saw huge silent triangular craft flying over that area in the early 1980’...Jack SarfattiTue, 21 Dec 2010 14:18:16 +0100Has David Bohm's realist quantum theory been falsified by experiments?

The Kerr-Newman solution is a vacuum solution. First consider Schwarzschild solution - modified to have dark matter in the interior.

https://stardrive.org/stardrive/index.php/all-blog-articles/myblog-ftd/ted-jacobsons-paper-on-gravity-entropy-holography-2nd-draft.html
<p>We have a chicken - egg problem - a horizon is part of a solution to Einstein's Guv + kTuv = 0. So we need a self-creating back-from-the-future post-selection effect for the whole thing to make sense on the cosmological scale. Note that Jacobson has a local argument based on the EEP/Rindler Horizon - very very clever. It shows to my mind that Zielinski's attempt to try to chuck the EEP is not correct. Similarly with the other philosophers, mathematicians, and theorists that Zielinski cites.<b...Jack SarfattiFri, 17 Dec 2010 10:42:03 +0100Gerard 't Hooft's suspicious argument on the holographic conjecture

<p>General Relativity is the local gauging of the four-parameter translation group T4, but the four spin 1 tetrads are the natural compensating gauge potentials not the spin 2 graviton second rank tensor metric field's Levi-Civita-Christoffel connection components. In all the quantum gravity schemes 't Hooft describes the tetrads are not mentioned.<br /> "A point made repeatedly by this author is that it is quite likely, at least philosophically<br /> more acceptable, that the quantum properties...Jack SarfattiTue, 14 Dec 2010 09:34:16 +0100Dark energy density is not back from the future Unruh advanced Wheeler-Feynman black body radiation
