Title

Abstract

It has been proposed that the nature of cosmological constant would be fundamentally related to the quantum nature of spacetime. The development of quantum gravity theory plays an important role for the quest of cosmological constant problem [1,2,3]. In this talk, the relationship between the cosmological constant problem and quantum gravity is discussed. The equivalence principle for quantum gravity is introduced and it leads to the scale invariant symmetry of the theory. The cosmological constant is an intrinsic property of the space-time-matter structure and its value could be reasonably calculated from the theory. Under the equivalent principle, the theory of quantum gravity is background independent and the classical picture for particles is a local equivalent representation of the quantum mechanical ones.
