  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.
