The Enigma in a Nutshell | Quantum Enigma: "Connectedness: Quantum theory tells that all things that have ever interacted are forever connected. For example, your friend’s freely made decision of what to do in Moscow (or on Mars) can instantaneously influence what you find in Manhattan. And this happens without any physical force being involved. Einstein called such influences “spooky actions.” They have now been demonstrated to exist. So far just for small things, but they are no less spooky."
