It from bit — a concrete attempt

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. 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 an omni-reaching superluminal messenger and by a binding 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, the duality, is added. Moreover, as an economic theory, it requires a single, de facto, input parameter. 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 in a small incision in the CA 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 in a toric lattice of a cellular automaton. In particular, it predicts that gravity, like the other static forces, is not quantized and that interaction between matter and antimatter is repulsive.
