THE-MATRIX Universe: Matrix Unified Framework of Causal Partial Order, Unified Time Scale, and Boundary Algebra

Building on unified time scale, boundary time geometry, and causal network--observer framework, this paper introduces a new ontological object---THE-MATRIX Universe. The core idea is: to view all observable structure of the universe as a large but strongly constrained operator matrix, whose sparsity pattern encodes causal partial order, whose spectral data realizes unified time scale, whose block structure corresponds to consensus geometry of multiple observers, and whose self-referential closed
