On social simulation in 4D relativistic spacetime

Agent-based modeling and simulation allow us to study social phenomena in hypothetical scenarios. If we stretch our imagination, one of the interesting scenarios would be our interstellar future. To model an interstellar society, we need to consider relativistic physics, which is not straightforward to implement in existing agent-based simulation frameworks. In this paper, we present the mathematics and algorithmic details needed for simulating agent-based models in 4D relativistic spacetime. These algorithms form the basis of our open-source computational framework, "Relativitization".
