Quantum "spooky action at a distance" travels at least 10,000 times faster than light

[choff]

My wildly speculative theory would be that spacetime is granular at Plank distance diameter, allowing a change in one entangled particle to be instantly transmitted to the other.

That's not so wildly speculative, choff. Sound's like Quantum Loop Gravity to me, which I have thought for many years is our best guess. Loop theory has a host of appeals, not the least of which is it can explain entanglement.

i posted a comment on the article.

looks like they aren't actually demonstrating FTL communication.

bummer.

European researchers determined a couple of years ago that, if space is granular, that the "grain-size" has to be 13 orders of magnitude SMALLER than the plank scale.

This puts the kabash on Quantum Loop Gravity and its cousins (like Extended Heim Theory).

Quantum entanglement is not any kind of FTL "communication" at all.

Right, information cannot be transferred and thus no communication. However, there is considerable debate as to how wave function collapse appears allow entangled particles to maintain state relationships over any distance. Thus a FTL mechanism of some sort is considered under certain interpretations of QM. Which makes it interesting.

fascinating stuff.

however, i was more impressed by this paper/insight from 2011: http://arxiv.org/abs/1109.6750v3

'Solving the Einstein-Podolsky-Rosen puzzle: the origin of non-locality in Aspect-type experiments'

- (cited by commenter to gizmag article). made sense to my small brain and is a short pithy paper.

the measurements are simply non-orthogonal. ( http://en.wikipedia.org/wiki/Orthogonality )

Quantum Mechanics from General Relativity: An Approximation for a Theory of Inertia

Starting with a detailed comparison of the original intentions of Bohr and Einstein in their development of Quantum Mechanics and General Relativity, Sachs shows that the goals of General Relativity are more insightful and subsume those of Quantum Mechanics. Where General Relativity is the forest, Quantum Mechanics is the trees.
By introducing the spinor variables of General Relativity that Sachs derived in his earlier work of General Relativity and Matter, he shows that the low energy form of his General Relativistic equations in the quaternionic basis are very simply Dirac's equations with interaction. To be clear, Quantum Mechanics is nothing more than a very useful, low energy approximation for a complete but more complex treatment under General Relativity in a quaternionic basis.

Then to ring up numerous "firsts" in Physics, it can be shown that there is force symmetry in matter and antimatter and that electrical charge is quantized. Not to be outdone, the next chapter finishes with an amazing derivation of Pauli's Exclusion Principle from first principles.

The broader view of this new Physics will lead the reader into a new order in Physics that breaks with current teaching. The annihilation of particle and antiparticle is shown instead to be a strong coupling of these fermions in a stable dipole unit. The Compton Effect, Blackbody radiation and the anomalous magnetic moment of the electron find new and refreshingly simple explanations. The world is ruled only by fermions. The "delayed action at a distance"of Feynman and Wheeler is restored to currency. The "advanced" solutions take their place beside the "retarded" solutions in a single, complete space-time.

The complete derivation of the full General Relativistic equations is detailed. This is followed by proof that the symmetric tensor part is nothing less than Einstein's original theory of General Relativity and, that the antisymmetric tensor part is Maxwell's equations.

Sach's following sections on elementary particle physics in this new paradigm should send earth tremors through CERN and FERMILAB. Lifetimes and masses of a number of "elementary particles" are discussed in great detail with fascinating new perspective. The muon is demonstrated to be a doublet excited state of the electron with a prediction of its mass and lifetime in accord with experiment.

Interesting. Any idea why they haven't published?
