Quantum gravity is expanded in powers of 1/D, where D is the number of dimensions. The extra dimensions are highly compactified. The expansion is gauge invariant. The leading term is equivalent to the iterated one loop matter corrections due to a free, massless scalar field without the \(\frac{1}{6} R\phi ^2\). term necessary for conformal invariance. The 1/D expansion is renormalizable. Flat space is found to be unstable under small fluctuations.
