  It is proposed that space is a four-dimensional Euclidean space with
universal time. Originally this space was filled with a uniform substance,
pictured as a liquid, which at some time became supercooled. Our universe began
as a nucleation event initiating a liquid to solid transition. The universe we
inhabit and are directly aware of consists of only the three-dimensional
expanding phase boundary. Random energy transfers to the boundary from thermal
fluctuations in the adjacent bulk phases are interpreted by us as quantum
fluctuations. Fermionic matter is modeled as screw dislocations; gauge bosons
as phonons. Minkowski space emerges dynamically through redefining local time
to be proportional to the spatial coordinate perpendicular to the boundary.
Other features include a geometrical quantum gravitational theory, and an
explanation of quantum measurement.
