Abstract

In the paper A New Approach to Quantum Gravity 1 we suggest a new approach to quantum gravity Using this theory we can study the noncommutative gravitational field in momentum space In this paper we obtain the general form of the Klein-Gordon equation in noncommutative gravitational field Then we find the symmetry associated with noncommutative gravity from the Klein-Gordon equation We study black hole in momentum space and conclude that the event horizon of black holes is formed by the dipoles in momentum space with limit state
