Can our spacetime emerge from anti -- de Sitter space?

Abstract

We present a model showing that our four-dimensional spacetime with the signature $(+,-,-,-)$ and almost vanishing positive curvature may have originated from a $b$-ary tree-like branching of a single discrete entity, and the $Ad{S}_5$ space related to this branching process.
