(1) The ability of subatomic particles to communicate instantaneously over vast distances (action at a distance) --at speeds greater than light-- and to exist in 'potential' locations not in one measurable local in space and time.

(2) Physicist David Bohm (1917-1992) explained nonlocality by saying that reality doesn't even exist. He suggested that the universe, in spite of its tangible appearance, is one huge hologram.

(3) nonlocal fish

Bohm explains the analogy of the "nonlocal fish" to demonstrate his theory of nonlocality: Pretend you are from another universe and have no idea what a fish is and have never seen an aquarium. You are shown a fish in a tank only you are in another room, observing the fish via two TV cameras set at different angles, transmitting their images onto two separate screens. There is only one fish in the tank, but you see two. When one moves the other moves immediately in a different, but concurrent way, as if they were communicating instantaneously. Bohm suggested that this is what is happening on the subatomic level in Aspect's experiment. We see two particles when actually there is only one.
