The subject of this paper is the geometry and topology of cosmological spacetimes and vector bundles thereon, which are used to model physical fields propagating in the universe. Global hyperbolicity and factorization properties of the spacetime and the vector bundle that are usually independently assumed to hold are now derived from a minimal set of assumptions based on the recent progress in differential geometry and topology.
