What profession does Action at a distance and Albert Einstein have in common?
Action at a distance In physics, action at a distance is the concept that an object can be moved, changed, or otherwise affected without being physically touched (as in mechanical contact) by another object. That is, it is the nonlocal interaction of objects that are separated in space. Pioneering physicist Albert Einstein described the phenomenon as "spooky action at a distance".
