You know, a fascinating question arises from this whole non-locality/Belle’s Theorem business: Since it states that quantum entities (photons, etc) which were once ‘entangled’ with each other at the subatomic level, then later separated, theoretically to unlimited distances, somehow remain in a state of instantaneous quantum connection with each other, then, since the entire universe was once quantumly entangled (within the big bang singularity), might the universe today be in some sort of instantaneous communication with itself? A single quantum entity? I once asked this question to Roger Penrose (Hawking’s mentor) at a lecture he gave a few years ago at Columbia University. He really loved the question which seemed to have never crossed his mind. Unfortunately, he went off into some related discussions which I didn’t quite follow.
I have wondered about these types of questions. I am interested in physics and math not so much for the actual results, as the theoretical implications. Epistemology and heuristics.
There is another very interesting result of Bell.
According to Einsteins theory, we can “rotate” the four dimensional space so that “time” becomes a linear dimension, and one of the linear dimensions rotates to become time.
The gist of this is that Bells theorem that talks about non-locality of space applies equally well - to time.
So, it would seem at least, that it is not theoretically impossible for you to open up your door tomorrow and see a baby pterodactyl there.
Or possibly - and I emphasize this is just educated speculation - change the past.
I have Bell’s set of lectures “Speakable and Unspeakable in Quantum Mechanics” I can understand alot of it, but in some places, the math is just too daunting.
And BTW, the last I heard, the Aspect experiments have been done, and managed to completely and decisively prove that Bell was right. That non-locality is a fact.
