What quantum mechanics tells us ... is surprising to say the least. It tells us that the basic components of objects - the particles, electrons, quarks etc. - cannot be thought of as self-existent". The reality that they, and hence all objects, are components of is merely "empirical reality". This reality is something that, while not a purely mind-made construct as radical idealism would have it, can be but the picture our mind forces us to form of [a] mysterious, non-conceptualisable "ultimate reality", not embedded in space and (presumably) not in time either. The quantum mechanical formalism ... compels us to consider that two particles that have once interacted always remain bound in a very strange, hardly understandable way even when they are far apart, the connection being independent of distance. Even though this connection-at-a-distance does not permit us to transmit messages, clearly it is real. In other words space, so essential in classical physics, seems to play a considerably less basic role in quantum physics. [Erwin] Schrdinger had even given [this reality] a name: entanglement, and had claimed entanglement is essential. A real breakthrough took place [when John Bell] published his famous inequalities, which - for the first time - opened a possibility of testing whether or not entanglement-at-a-distance had experimentally testable consequences. Entanglement-at-a-distance does physically exist, in the sense that it has physically verifiable (and verified) consequences. Which proves beyond a shadow of a doubt that some of our most engrained notions about space and causality should be reconsidered.
