  If Newtonian gravitation is modified to use surface-to-surface separation
between particles, it can have the strength of nuclear force between nucleons.
This may be justified by possible existence of quantum wormholes in particles.
All gravitational interactions would be between coupled wormholes, emitting
graviton flux in proportional to particle size, allowing for the point-like
treatment above. When the wormholes are 1 Planck length apart, the resultant
force is 10^40 times the normal gravitational strength for nucleons.
