Compactifying M-theory on 7-manifolds with exceptional holonomy group G2 provides a relatively unexplored route to minimally supersymmetric 4-dmensional physics. Unlike the heterotic and F-theory routes, the mathematical tools needed to systematically construct and study these manifolds do not yet exist. This has started to change, with new constructions available which produce millions of examples. In order to obtain physically realistic models with non-abelian gauge symmetry and chiral matter, we must learn how to study singular G2 spaces. I will report on recent progress in this direction (joint work with Jim Halverson), studying singular G2 spaces as limits of nonsingular ones.
