Abstract A model of the universe is developed using a constructive approach. It is a deterministic, discrete, finite (including time), spatially three-dimensional structure with an array of integer registers attached to each node, forming a toric cellular automaton. Information (bits) travels through the lattice mainly as spherical wavefronts at the speed of light, being eventually reissued when interacting. These collisions are assisted by a momentum compensation mechanism and by a bonding property. Motion is achieved with the combination of a kinematic rule plus a borrow/return scheme with the vacuum. The asymmetry of matter and antimatter and the Cosmic Microwave Background Radiation are explained when a new charge is added. Moreover, as an economic theory, it has required very few input parameters so far. A quantitative analysis is initiated when the bird's eye view used to develop the automaton core gives way to the use of operator mechanics and large number approximations in a small incision in the grid. In short, Physics (it) is conjectured to emerge from this ontological, unified picture as the system evolves from a highly symmetric unphysical hologram pattern of registers defined at a sub-Planckian scale to a physical, everlasting Poincaré cycle. The foundational stance is: This is not an intepretation of Quantum Mechanics, but a deeper description of nature. In particular, it predicts that gravity, like the other static forces, is not quantized and that interaction between matter and antimatter is repulsive.
