Abstract: In the present short letter we aim at deriving the cosmic ordinary effective quantum gravity energy density as well as that of dark energy from the SO (10) Lie symmetry group of grand unification. Remarkably the derivation makes no use of quantum mechanics and remains largely classical except for nonclassical geometry and topology. Finally our mai... Show More

Abstract: In the calculation of structures in beams with spherical plain bearings (SBSPB) static bindings, movements are continuous, while rotations are staple to a node where a ball. is located in Dynamics, in several calculation codes, and mechanical frictions are often supposed to be neglected. In this paper, we proposed a modeling of the SBSPB which take... Show More
