Geometry-information duality: Quantum entanglement contributions to gravitational dynamics

  Geometry-Information Duality: Quantum Entanglement Contributions to Gravitational Dynamics In recent years, a profound idea has emerged at the intersection of quantum mechanics and general relativity— the geometry-information duality . At its core, this concept suggests that the very fabric of spacetime may be shaped by the informational structure of quantum systems. Instead of viewing gravity solely as the curvature of spacetime due to mass and energy (as in Einstein’s theory), modern theoretical physics is exploring how quantum entanglement—the mysterious correlation between particles—may underpin the structure and dynamics of spacetime itself . One of the foundational insights in this field comes from the AdS/CFT correspondence , a duality proposed in string theory. It connects a gravitational theory in a curved spacetime (Anti-de Sitter space) with a quantum field theory on its boundary. This framework revealed that entanglement entropy , a measure of quantum information, c...

Applying conservation agriculture practices as a strategy to control soil erosion and carbon sequestration
