Implications of General Covariance and Maximum FourDimensional YangMills Gauge Symmetry
Abstract
General covariance and maxium fourdimensional YangMills gauge symmetry lead to these results: (1) Gravity is characterized by a dimensionless constant F~10^{19} (2) the Newtonian force is always attractive; (3) spacetime has a torsion; (4) gravitational spinforce between two protons is about 10^{19} times stronger than the corresponding Newtonian force. A possible experimental test is discussed.
