====Bell's (non-locality) Theorem====

"Irish physicist John Stewart Bell considered the EPR system and showed with a
devilishly clever proof that all conceivable models of Reality must incorporate
this instant connection. What Bell showed is that despite the fact that
Relativity prohibits instantaneous connections, despite the fact that no such
connections have ever been observed either in EPR experiments or any other,
despite the fact that quantum theory itself predicts no observable instant
connections, despite all these considerations from Fact and Theory, the Reality
of the EPR particles is such that their initial contact must create an
instantaneous voodoo-style link between them below the level of Appearances.

"Bell's Theorem (Reality must be non-local) is remarkable for several reasons: 1)
it is a mathematical proof, not a conjecture or speculation; 2) it is a proof
about Reality not Appearances. How often does one find such a window into the
nature of reality? 3) it is counter-intuitive: why should everywhere local facts
need to be supported by a non-local reality?

"THERE ARE LOTS OF THINGS that are being kept from the public as far as the
subjects of physics and consciousness are concerned . . . Bell's Theorem was
proved in 1964, and it is still not taught in physics classes, and you don't
hear it on your science news programs. A theorem is a proof, and no one's found
a flaw in this theorem. It's such a simple proof that a high school kid can
understand it . . . so physicists can understand it. They have various ways of
trying to ignore it, but it can't be refuted because it's so simple."

"A non-local interaction links up one location with another without crossing
space, without decay, and without delay. A non-local interaction is, in short,
unmediated, unmitigated, and immediate." --[[Nick Herbert]]
