  The fact that mass has an effect on surrounding space is the first essential
element of general relativity. This paper unifies this mass/space distinction
of general relativity with Newtonian gravity at a subatomic scale and with
reported experimental findings of the last century. The subatomic distinction
of mass concentration mainly in nucleons surrounded by empty space as we know
it now was not known when the general relativity was written. The author uses
this distinction to set forth a consistent classical equation of gravity valid
to the Planck length and peeps into the quantum world. It is difficult to
exaggerate the importance of fundamental nuclear theory for the understanding
of matter in the universe and its cosmological evaluation, and also for the
inclusion of gravity in the unified family of all four forces.
