Show me a quantum theory of gravity, and I'll tell you the answer. Gravitons, unlike photons have been postulated but not yet found or proven. The task of a large number of theoretical physicists is to find a way of uniting quantum theory (which predicts gravitons) with general relativity. Superstring theory is a good, but as yet unproven, candidate for a theory of everything. Perhaps when a theory of gravitons exists, I will know the answer.
