It should be thought of as a collection of more fundamental "microscopical" entities (atoms of geometry), much like a solid system, in which an atomic (classical) structure must be first recognized in order to ensure a correct and meaningful quantization procedure. In other words, we claim that the classical limit from a quantum theory of gravity could not give a four dimensional Einstein spacetime directly, but requiring {\it a further} macroscopical limit. This is analogous to a material medium, whose complete description does not come from any quantized field. We also discuss a possible realization of this hypothesis for black hole spacetimes.This note contains the conceptual framework of the essay presented in the Gravity Research Foundation Competition, 2004High Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
