to the speed of light be constant,and be isotropic must produce a distortion
in the space-time,that thence are curves with vsrying curvatures of way uniform,it is are hyperboloid rotations
into at the ellipsoid rotations.thence appear the inertial frames with conservations of laws being equivalent between its.when appear gravitational fields them the varying curvaturs already are not more uniformly.
