Hyperverse, 5-dimensional gravity and multiverses as nested Gogberashvili shells

Résumé

We consider the Hyperverse as a collection of multiverses in 5-dimensional 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 $\varepsilon_k^{}$ its thickness then $G\sim\varepsilon_k^{}g_k^{}$. The physical universe is supposed to be one of those shells inside the local nested bouquet called Local Multiverse. We relate 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.
