This paper develops a distributed-systems reading of causal order, locality, and the formation of facts in a relativistic universe. It extends the interpretive framework of The Universe as a Consistency-Constrained Information History, in which physical reality is redescribed as a causally consistent history of information updates rather than as a collection of objects independently existing within spacetime. The paper asks what kind of consistency structure such a history can possess if it has no privileged global clock, no instantaneous long-distance coordination, and no external coordinator. The answer is not that the universe literally runs a distributed protocol. Rather, distributed systems provide a…
