The basic principle is that particles of matter are not restricted to local interactions. They can have interactions outside their local system with no limit on distance.
A cording to
's Theorem developed by John Stewart Bell shows that no physical theory of local hidden variables can ever reproduce all of the predictions of Quantum Mechanics. This does leave open the possibility of non-local hidden variables. Bell
The implications are that subatomic particles clearly exhibit non-local behavior showing that our notions of location do not apply at the fundamental levels of reality. Quantum Nonlocality creates a link betw
