We propose a model for the universe based on Jordan algebras. The action consists of cubic terms with coefficients being the structure constants of a Jordan algebra. Coupling constants only enter the theory via symmetry breaking which also selects a physical vacuum. "Before" the symmetry breaking the universe is in a pre-geometric state where it makes no sense to talk about space or time, but time comes into existence with the symmetry breaking together with a Hamiltonian which can create space from "nothing" and in some cases can propagate the space to macroscopic size in a finite time. There exists symmetry breaking which results in macroscopic spacetime dimensions 3, 4, 6 and 10, based on the Jordan algebras of Hermitian 3x3 matrices with real, complex, quarternion and octonion entries,respectively.

The emergence of the universe
A Jordan-algebra W3 model knits one-dimensional universes via wormholes into a 4D spacetime; a singular point of its modified Friedmann equation is claimed to explain the hierarchy and the small coupling g.

Atmospheric muon flux suppression at potential new low-radiation underground physics laboratory in Israel
The muon flux inside the Kokhav HaYarden tunnel is measured at 3.75 x 10^-6 cm^-2 s^-1, about 4,456 times lower than at sea level.
