Emergence of Minkowski Spacetime by Simple Deterministic Graph Rewriting

The causal set program and the Wolfram physics project leave open problem of how a graph that is (3+1)-dimensional Minkowski spacetime according to its simple geodesic distances could be generated solely from deterministic rules. This paper provides solution by describing rules characterize discrete Lorentz boosts between 4D lattice graphs, which combine further form Wigner rotations produce isotropy lead emergence continuous group spacetime. On such speed light, proper time interval, as well length are all shown highly accurate.
