  Extending black-hole entropy to ordinary objects, we propose kinetic entropy
tensor, based on which a quantum gravity tensor equation is established. Our
investigation results indicate that if N=1, the quantum gravity tensor equation
returns to Schrodinger integral equation. When N becomes sufficiently large, it
is equivalent to Einstein field equation. This illustrates formal unification
and intrinsic compatibility of general relativity with quantum mechanics. The
quantum gravity equation may be utilized to deduce general relativity, special
relativity, Newtonian mechanics and quantum mechanics, which has paved the way
for unification of theoretical physics.
