The Emergent Spacetime Hypothesis:A Novel Framework for Quantum Gravity and Cosmological Structure Formation

This manuscript presents a novel theoretical framework in which spacetime is not a fundamental entity but an emergent phenomenon arising from quantum entanglement dynamics and thermodynamic irreversibility. The core innovation is a rigorous mathematical derivation of the thermodynamic arrow of time from first principles, specifically linking it to CP violation in the electroweak sector. The framework integrates concepts from quantum gravity and cosmology, proposing modified gravitational dynamics that include an entanglement-derived stress-energy tensor. It yields distinct, falsifiable predictions, including a characteristic suppression and modulation pattern in the low-multipole region of the CMB power spectrum and an enhanced baryon asymmetry signature. The model is empirically validated against Planck 2018 data, showing a statistically significant improvement over the standard ΛCDM model, and proposes specific tests for upcoming experiments like CMB-S4 and LHCb Run 3. The work aims to resolve longstanding conceptual problems like the nature of time in quantum gravity while providing a concrete path for experimental verification.
