Current theoretical physics posits that spacetime is likely an emergent phenomenon rather than a fundamental background, arising from deeper quantum substrates or informational structures.

Entanglement and Holography The "It from Qubit" framework suggests that spacetime geometry is directly stitched together by quantum entanglement. In the context of the AdS/CFT correspondence, the Ryu-Takayanagi formula relates the entanglement entropy of a boundary field theory to the area of a minimal surface in the bulk spacetime. Research indicates that if the entanglement between spatial regions drops to zero, the geometric connection between them dissolves. Furthermore, the Einstein field equations—describing gravity—can be derived directly from the thermodynamics of this entanglement.
