Non-locality is a phenomenon in quantum physics where particles that are entangled seem to influence each other instantaneously regardless of the distance between them. This apparent violation of classical notions of cause and effect is sometimes referred to as “spooky action at a distance” or quantum entanglement.
In the context of the holographic universe, the concept of non-locality suggests that the interconnectedness implied by the holographic nature of reality might involve non-local connections between seemingly distant parts of the universe.
