Jan 30 at 15:24 comment added Anton Petrunin @WillieWong, you are right, still the question is formulated differently and it is better to write an answer (now it is removed from "unanswered questions").
Jan 30 at 12:12 comment added Willie Wong Yes, I am aware that's how it actually works. But the OP is evidently confused, if you look at the comment thread below the question.
Jan 30 at 4:32 comment added Anton Petrunin @WillieWong The null vector that is normal to the null cone is tangent to it (the metric is not Riemannian).
Jan 30 at 2:16 comment added Willie Wong As posed by the OP (including even the clarifying comment) the question is unanswerable, since the initial setup is ill-defined.
Jan 30 at 2:11 comment added Willie Wong Your answer is posted two years after the OP's clarifying comment, in which it was clearly stated that the intention is for geodesics transverse to the cone, not the geodesics tangent to the cone. So it doesn't answer the question at all.
