Abstract: We describe a CDT-like model where breaking of W (3) symmetry will lead to the emergence of time and, subsequently, of space.Surprisingly, the simplest such models which lead to higher dimensional spacetimes are based on the four "magical" Jordan algebras of 3×3 Hermitian matrices with real, complex, quaternion and octonion entries, respectively.The simplest symmetry breaking leads to universes with spacetime dimensions 3, 4, 6, and 10.
