Brian Greene's NOVA Elegant Universe

Consider the formula:
Potential Energy = G(M-m)m/L_a where
(M-m) is the rest of the universe and L_a is
distance between the mass m
and the mass of the rest of the universe..

Not the earth (m_1) and moon (m_2).
G(m_1)(m_2)/L_b.
As L_b increases L_a decreases..

Potential and Kinetic energies must be
considered relative to the rest of the universe.
This ,simple observation , has corrected the
problems previously
involved in the definition of gravitry by
Newton and Einstein. This unifies quantum
and gravity mechanics.
