Quantum weirdness: what is quantum reality? (Introduction)

Another breathless commentary on the fact that we don't know what is going on:

"Kuhn pointed out, when enough “anomalies”—empirically undeniable observations that cannot be accommodated by the reigning belief system—accumulate over time and reach critical mass, paradigms change. We may be close to one such a defining moment today, as an increasing body of evidence from quantum mechanics (QM) renders the current paradigm untenable.

"The problem is that, according to QM, the outcome of an observation can depend on the way another, separate but simultaneous, observation is performed. This happens with so-called “quantum entanglement” and it contradicts the current paradigm in an important sense, as discussed above. Although Einstein argued in 1935 that the contradiction arose merely because QM is incomplete, John Bell proved mathematically, in 1964, that the predictions of QM regarding entanglement cannot be accounted for by Einstein’s alleged incompleteness.

"The only alternative left for those holding on to the current paradigm is to postulate some form of non-locality: nature must have—or so they speculate—observation-independent hidden properties, entirely missed by QM, which are “smeared out” across spacetime. It is this allegedly omnipresent, invisible but objective background that supposedly orchestrates entanglement from “behind the scenes.”

"It turns out, however, that some predictions of QM are incompatible with non-contextuality even for a large and important class of non-local theories. Experimental results reported in 2007 and 2010 have confirmed these predictions. To reconcile these results with the current paradigm would require a profoundly counterintuitive redefinition of what we call “objectivity.” And since contemporary culture has come to associate objectivity with reality itself, the science press felt compelled to report on this by pronouncing, “Quantum physics says goodbye to reality.”

"The tension between the anomalies and the current paradigm can only be tolerated by ignoring the anomalies. This has been possible so far because the anomalies are only observed in laboratories. Yet we know that they are there, for their existence has been confirmed beyond reasonable doubt. Therefore, when we believe that we see objects and events outside and independent of mind, we are wrong in at least some essential sense. A new paradigm is needed to accommodate and make sense of the anomalies; one wherein mind itself is understood to be the essence—cognitively but also physically—of what we perceive when we look at the world around ourselves."

Comment: Since mind/consciousness affects every quantum observation, the bolded statement above must be taken very seriously. Quantum reality may be God's mind at work, as if the universe is an extension of His mind.
