    I made a technical correction, and added Idea and Applications.

    Thanks.

    I am not quite following where the reference to a “theory of everything” comes from, though.

    added (here) statement of Bernal & Sánchez 2005, Thm. 1.1 that a smooth globally hyperbolic spacetime admits a smooth foliation by smooth spacelike Cauchy surfaces.
