You omitted my last bit: "...photons from distant sources". Yes, we can run EPR experiments, and have done so. I don't believe every photon from distant sources is entangled (and we might not know if it was...you have to measure the both entangled particles to confirm). To the best of my knowledge.

Not a nutcase. Perhaps a bit poetic. But you're aware of more physics than probably 95% of the population. You see more the numinous. If I take off my physicist hat, and look up at the sky, I do too. It's very overwhelming to be away from city lights on a clear moonless night.

The wormhole article you cited is highly speculative. It also proceeds on a potentially false assumption that QM and GR are unite-able. I've been reading that people are rethinking Grand Unification, and that perhaps gravity is not compatible (or unifiable) with the other three forces. And no theory of quantum gravity appears to work. Always a bad idea to say "it can't be done", but many are starting to think that maybe it can't be.
