Nonlocal Vacuum Information Dynamics (NVID): An Effective Framework for Spacetime Memory and Network Interactions

We present an effective phenomenological framework referred to as NonlocalVacuum Information Dynamics (NVID), in which spacetime is modeled as aninformation-processing medium. The framework integrates four conceptual components: (i) nonlocal vacuum response that can contribute to stabilizing wormholegeometries; (ii) dynamical information currents propagating in spacetime; (iii) nonlinear screening that regulates observation-induced perturbations; (iv) boundaryinformation memory layers that store and redistribute information on spacetimeboundaries. Within this formulation the vacuum is described as an informationcarrying medium while spacetime boundaries function as dynamical memory layers.The resulting theory forms a coupled bulk–boundary system in which Einstein-typegeometric dynamics in the bulk is linked to nonlinear reaction–diffusion memorydynamics on wormhole throats. Stored boundary information modifies the effectivethroat geometry and produces observable signatures including echo trains, relaxation spectra, memory echoes, network beat modulation, and geometry-inducedecho delay drift in gravitational-wave signals. Clear falsifiability criteria are identified, making the framework testable with next-generation gravitational-wave detectors such as the Einstein Telescope, Cosmic Explorer, and LISA.
