Simulation World Theory — A Spacetime Causal Framework Based on Information Computation

Description: This paper reinterprets spacetime as a real-time rendering system with finite computational resources, and proposes a unified causal framework for gravity, black holes, dark matter, and dark energy.

Why the universe keeps expanding while we cannot find those "invisible masses"? This paper proposes a bold yet logically self-consistent hypothesis: the spacetime we perceive is essentially a real-time rendering system with finite computational capacity, created by an external entity for some purpose (one plausible conjecture being "for external observation"). Starting from the simplest premise—"computational resources are finite"—we attempt to provide a unified causal chain for phenomena such as gravity, time, black holes, dark matter, and dark energy. This is not science fiction, but a serious metaphysical framework intended to offer a supplementary perspective from information science to existing physical observations.
