The quantum gravity mainstream versus my problem of time

Abstract

Abstract A critical reflection on the mainstream thinking regarding the quantum gravity problem is presented, revolving around the status of certain intuitive starting assumptions, that are usually kept implicit. The powerful AdS/CFT correspondence is reviewed. In the way it is used, it is actually by construction avoiding the quantum–gravity conflict. It is detached from semiclassical black hole physics and using it for these purposes does not make sense. The fact that the diffeomorphism of GR is sacrificed in the context of the Unruh effect by tracing out the quantum information beyond the horizon, is a separate postulate that has not been independently verified. The information paradox is explored: why claim that macroscopic black holes are subjected to eternal unitary time evolution, while there are no other macroscopic objects known accomplishing this feat?
