The Kinky Singularity Conjecture
To state the conjecture we first need a
Let (M,g) be an asymptotically flat spacetime which is topologically of the form C x R, where R denotes the real line and C denotes some asymptotically flat 3-surface which is everywhere spacelike outside of some compact set U in C. Then we say that the spacetime (M,g) describes an asymptotically flat kink if kink(C;g) is non-vanishing (here, kink(C;g) denotes the kink number of g relative to the surface C, i.e., kink(C;g) is the degree of the map from C to the three-sphere S(3), which is defined by a timelike vector field V induced by g).

Given this definition we can then state the
Let (M,g) be a chronological spacetime describing an asymptotically flat kink and satisfying the strong and generic energy conditions. Then (M,g) is timelike and null geodesically incomplete.
