Also how can local causality be violated?
Local causality refers to the idea that events that occur in one location are only influenced by events that occur in its immediate vicinity. In other words, there is no action at a distance, and the relationship between cause and effect is limited to the local area.
Global causality, also known as non-local causality, suggests that events in one location can be influenced by events that occur in distant locations. This is in contrast to local causality, which states that only nearby events have an effect on each other.
An example of local causality in science is the principle of causality in classical mechanics. In this theory, the effects of an object's motion are determined solely by the forces acting on it in its immediate surroundings, rather than being influenced by distant forces.
Local causality is closely related to determinism, which is the idea that all events are caused by previous events and that there is no randomness or free will in the universe. This is because local causality suggests that events are determined solely by their local causes.
No, quantum mechanics does not support local causality. In fact, the principle of non-locality, where events in one location can be influenced by events in another location, is a fundamental aspect of quantum mechanics. This has been demonstrated through various experiments, such as the Bell test, which have shown that particles can be entangled and affect each other's behavior instantaneously, regardless of distance.
