Resumen:
We present the first explicit global conformal diagramof Kerr spacetime and discuss some implicationson the causal structure.For this construction we use a new doublenull coordinate system for Kerr spacetime, which we have recently presented.These null coordinates are smooth everywhere andare naturally adapted to thehorizons and to the null infinities.In this setting there naturally appears a family of spheres that are parameterized by $r_s$, which are the intersections of both null coordinates, and $r_s$ can be thought of as the extension of the tortoise coordinate for the Kerr spacetime.
