Hyperverse, 5-Dimensional Gravity and Multiverses as Nested Gogberashvili Shells

Abstract

We consider the Hyperverse as a collection of multiverses in 5-dimen-sional spacetime with gravitational constant G . Each multiverse in our simplified model is a bouquet of nested spherical Gogberashvili shells. If g k is the gravitational constant of a thin shell S k and ε k its thickness then G ∼ ε k g k . The physical universe is supposed to be one of those shells inside the local nested bouquet called Local Multiverse . We re-late this construction to Robinson-Trautman metrics describing expanding spacetimes with spherical gravitational waves. Supermassive astronomical black holes, located at cores of elliptic/spiral galaxies, are also conjecturally described within this theory. Our constructions are equally consistent with the modern theory of cosmological coupling.
