Gravity is the one asymmetry on earth.  Magnetism on earth is symmetry with N and S on earth.  Electric field is also symmetrical with + and - on earth.  Such symmetrical forces of electric and magnetic fields cannot as well explain the chiral nature of life’s molecules.  But RBL theory of gravity better explains homochirality of biomolecules as gravity on earth is asymmetrical with mostly Br gravity on earth. In this work, RBL theory is developed more that Br gravity on earth is what broke the symmetry of chirality for one chirality for life on earth. Prior theories of homochirality do observe magnetic effects on physical processes, but magnetic fields on earth are not asymmetric, macroscopically.  So different magnetic fields can alter chirality and the two polarities can manifest both chiralities.  But why is there only one chirality in healthy organisms?  RBL’s theory explains homochirality better by his gravity theory.  Gravity on earth is asymmetrical. RBL theory determines earth’s gravity and its Br nature and irrational, fractional nature acts on stable isotopes of nonzero nuclear magnetic moments 13C and 17O in aqueous solvents on earth to organize organic compounds with preferred chirality for origin of life on earth. Such basis for life’s chiral origins is consistent with other aspects of RBL’s theory as isotopic enrichment in living organism can alter the primordial isotopic blueprint of chirality for altering metabolism for aging and disease.
