Thispaper present threetheorems on a Lorentz manifoldwhich yield an on pointprediction ofthefine structureconstant, and as the result theawaitedequation of coupling magnitudes.this paper than allow us tounify QM with GR. The equation also predicting the magnitude of any additional element in the series, the next element should stand at ratio of 1/850 compared to the strong interaction. Updated to 7.9.21
