Choquet-Bruhat's weak cosmic censorship conjecture

Let $(\Sigma,\leftidx{^\Sigma}{\mathbf{g}}{},\leftidx{^\Sigma}{\mathbf{K}}{},\mu,J)$ be generic asymptotically flat initial data, and let $(M,\mathbf{g})$ be its maximal globally hyperbolic development (MGHD). A future null infinity $\mathscr{I}^+$ is complete when its null geodesic generators are complete with respect to the conformal metric of the maximal development. Choquet-Bruhat's weak cosmic censorship conjecture. The MGHD $(M,\mathbf{g})$ of generic asymptotically flat initial data possesses a complete future null infinity $\mathscr{I}^+$. This is one of the two standard formulations of cosmic censorship and is intended to exclude naked singularities visible from infinity. Its general validity remains open.
