Read this response and predict the preceding dialog. In particular, contrary to the popular claim that quantum mechanics and general relativity are fundamentally incompatible, one can demonstrate that the structure of general relativity essentially follows inevitably from the quantum mechanics of interacting theoretical spin-2 massless particles (called gravitons). No concrete proof of gravitons exists, but quantized theories of matter may necessitate their existence.

Read the following conversation:
 -What is meant by Quantum gravity?
 -At present, one of the deepest problems in theoretical physics is harmonizing the theory of general relativity, which describes gravitation, and applications to large-scale structures (stars, planets, galaxies), with quantum mechanics, which describes the other three fundamental forces acting on the atomic scale.
 -Are there any other interesting aspects about this article?
 -This problem must be put in the proper context, however.
 -In what context?
