| contents | We propose a 2+1d simulation of Energetic Causal Sets (ECS). These are a class of Causal Sets where the agency of time and its irreversibility are taken as fundamental. Events are endowed with energy-momentum conservation laws being applied at events dictating the dynamics of the Set. Unlike Causal Sets, ECS have three orders, a birth total order, a partial dynamical order which prescribes the flow of energy-momentum between events and a partial causal order that arises from the embedding of these events in Minkowski spacetime. These orders aren't necessarily in agreement with each other, something we call discausality or disordered causality. We therefore explain our first attempts at expanding to two spatial dimensions the simulations of the Energetic Causal Set model to see if we can still obtain reversible dynamics from fundamental time-irreversible laws like in the 1d case. |
