Einstein’s theory of relativity and its associated "Block Universe" concept—monuments of modern physics—established the mathematical consistency of Lorentz transformations and the constancy of the speed of light c, while inadvertently forcing physics into an extreme determinism that freezes past, present, and future into a static picture. This paper redefines this geometric spacetime concept from the perspective of the Dejima Model (Universe OS), proving that Einsteinian speed-of-light constancy and the Block Universe do not contradict the overarching universe model, but are fully subsumed as a local, steady-state limit (a lower-order approximation) valid only in regions where the systemic response speed remains practically uniform. Furthermore, we propose a multi-bulk structure where the holographic screen—generated from fundamental pair creation from 0 (Null) and "Response Viscosity c (synchronization delay)"—serves as a shared "Information Base (OS / Data Layer)," from which multiple "bulks (phase spaces / physical universes)" with distinct parameters self-emerge and differentiate. While these bulks do not geometrically collide in 3D surface space, they remain deeply entangled at their core via the shared base screen. We demonstrate that this transient phase interference transmitted through the underlying base constitutes the true physical identity of both dark matter and quantum non-locality.
