How does non-locality fit into the picture?

Hi Cecil

Non locality is another description of the phenomenon, or 'spooky action at
a distance' is another term that has been used. The instantaneous
interaction of entangled particles, no matter what the distance, follows as
a mathematical consequence of quantum theory.

These actions have been observed in laboratories but to date no one has come
up with an entirely satisfactory explanation for what is going on. Similar
weird observations in particle accelerators show particle tracks
disappearing and reappearing at some distance away. Richard Feynman touched
upon the possibilities of these events happening when he came up with
Feynman diagrams to describe the interaction of particles with photons.
Certainly at sub atomic scales, time appears to be somewhat elastic and
reversible under particular conditions.

I personally feel (with very little justification) that wave particle
duality breaks down if velocities exceed the speed of light and in the
absence of one or the other, an object effectively disappears from our
perception (and perhaps in effect from our universe).
