where [r.sub.G-pi] is gravitational-radius of the pi-meson.
Since the classical-radius of the electron re = [e.sub.2]/[m.sub.e][c.sup.2], radius of the pi-meson [r.sub.pi] = [Ng.sup.2]/[m.sub.pi][c.sup.2] and the radius of nucleus of an atom [r.sub.n] can also be expressed in the similar manner by inserting the masses of the electron, the pi-meson and the nucleus in the right-hand-sides of the above expressions, though they are bound by electric-force, strong-force and the nuclear-force respectively, it suggests a possibility that the currently-believed fundamental-forces may not be truly fundamental; rather, the law followed by them, as expressed in the expressions (4) to (9), may be more fundamental than the "fundamental-forces"; and the strengths of forces may be getting decided by these expressions (4) to (9).
