TL;DR

This paper demonstrates the theoretical possibility of a nested hierarchy of inflating brane worlds across multiple dimensions, each created from nothing and existing beyond Rindler horizons, forming an infinite tower of such universes.

Contribution

It introduces a novel construction of a nested tower of inflating brane worlds with increasing dimensions, expanding the theoretical landscape of higher-dimensional cosmology.

Findings

Existence of (n-1)-dimensional inflating brane worlds beyond Rindler horizons.

Construction of an infinite tower of successively higher-dimensional brane worlds.

Each brane world is instantonically created from nothing.

Abstract

It is shown that an (n-1)-dimensional inflating brane world instantonically created from nothing can exist in the region beyond the Rindler horizon of the Lorentzian spacetime associated with another inflating brane world in n dimensions which is also instantonically created from nothing. Generalizing this construction we obtain an unbounded from above tower of successive brane worlds, each having one more dimension than the one which it nests and one less dimension than the one which nests it.
