When we consider that all quanta have interacted at some point in the
history of the cosmos … and that there is no limit on the number of
correlations that can exist between these quanta, this leads to [a]
dramatic conclusion -- nonlocality is a fundamental property of the entire
universe….The indivisible whole whose existence is inferred … cannot be
measured or observed, we confront here an "event horizon" of knowledge
where science can say nothing about the actual character of this reality.

two points at faster than the speed of light in The Non-local Universe:
