Theory of the Spatial-Material Continuum (SMC). Version 2.0

This work develops the Theory of the Spatial-Material Continuum(SMC), integrating physics, cosmology, and cognitive sciences. Keyinnovations include:- Complex coherence ξ = eiθ|ξ| with phase dynamics and noise; -Extended Lagrangian with linkage terms Φ − ρ − ξ and dissipation; -Emergent time dt = dτ1−|ξ|2 ; - Energy-momentum tensor with entropiccontribution; - Quantization via [ˆρ, ˆξ] = iℏρP ; - Consciousness modelbased on ξneur with threshold 0.8.Numerical methods and experimental predictions for LIGO, EHT,CMB, and neurobiological tests are provided.
