Again, we think of an emitting antenna.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We know that \u201cs\u201d can stand for spin, and that electrons have spin. The electrons in the antenna may impart spin into a \u201ctensor space T<sub>s<\/sub><sup>r<\/sup> \u201c ([1], pg. 209], where \u201cr\u201d is the vector away from the antenna, and \u201cs\u201d is the spin. What we can liken this to is a corkscrew in a gravitational field. Each corkscrew \u201cs is a direct sum of simple ideals: s<sub>1<\/sub> + \u2026 +s<sub>k<\/sub>\u201d ([2], Appendix 5, pg. 279)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To send these corkscrews out in all directions from an antenna is a phenomenal amount of work. It is not absolutely necessary that accelerated free electrons expand for this to occur, though they would at least absorb gravitons at a greater rate than a free electron at rest or traveling at constant velocity in a straight line.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is not known what percentage of these corkscrews would be left-handed. When two electrons are near each other, \u201c(\u03b2<sup>i<\/sup>) is invariant by the left translation\u201d ([2], pg. 207), and they repel each other.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Furthermore to the Ricci tensor field containing spin, there are the following two corollaries:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cCorollary 5.5&nbsp;&nbsp; <em>If M is a compact Riemannian manifold with vanishing Ricci tensor field, then every infinitesimal isometry of M is a parallel vector field<\/em>.\u201d ([2], pg. 251)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cCorollary 5.6&nbsp;&nbsp; <em>If a connected compact homogeneous Riemannian manifold M has zero Ricci tensor, then M is a Euclidean torus<\/em>.\u201d ([2], pg. 251)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As the output from an emitting antenna turns into tori, there is a \u201cconcatenation of paths\u201d ([3], pg. 229].<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Of course, as these tori wear out, they disintegrate, because of \u201ca theorem of Weyl that any representation of a semisimple Lie algebra is completely reducible\u201d ([2], Appendix 5, pg. 279]. We now know that these Lie algebras are reducible to gravitons.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[1] Kobayashi, Shoshichi and Nomizu, Katsumi, \u201cFoundations of Differential Geometry Volume II\u201d, John Wiley &amp; Sons, Inc., c. 1969<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[2] Kobayashi, Shoshichi and Nomizu, Katsumi, \u201cFoundations of Differential Geometry Volume I\u201d, John Wiley &amp; Sons, Inc., c. 1963<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[3] Mackenzie, Kirill C.
