Finite action principle and Hořava-Lifshitz gravity: Early universe, black holes, and wormholes

The destructive interference of the neighbouring field configurations with infinite classical action in gravitational path integral approach serves as a dynamical mechanism resolving black hole singularity problem. It also provides an isotropic and homogeneous early universe without need inflation. In this work, we elaborate on finite framework Horava-Lifshitz gravity -- ghost-free QFT. Assuming mixmaster chaotic solutions projectable H-L theory, show that beginning is isotropic. Furthermore, selects only regular black-hole spacetimes. We comment possibility traversable wormholes theories higher curvature invariants.
