Entanglement ~ What Probablity Means for Social Reality

By now, you know how fascinated I am with quantum physics and how I enjoy applying it to my field of study and expertise- Sociology. I just read a truly incredible piece about the arrow of time and entanglement. I paste here a bit of that article (followed by my own brief response) describing what has been and is still being considered extraordinary in the realm of quantum physics. 
Physicists are unmasking a more fundamental source for the arrow of time: Energy disperses and objects equilibrate, they say, because of the way elementary particles become intertwined when they interact — a strange effect called “quantum entanglement.” 

This means that objects and their environment intertwine when they interact or order to reach equilibrium said Nicolas Brunner, a quantum physicist at the University of Geneva. “But when it comes to explaining why it happens, this is the first time it has been derived on firm grounds by considering a microscopic theory.”  

If the new line of research is correct, then the story of time’s arrow begins with the quantum mechanical idea that, deep down, nature is inherently uncertain. An elementary particle lacks definite physical properties and is defined only by probabilities of being in various states. For example, at a particular moment, a particle might have a 50 percent chance of spinning clockwise and a 50 percent chance of spinning counter-clockwise. 

Northern Irish physicist John Bell says there is no “true” state of the particle; the probabilities are the only reality that can be ascribed to it. When two particles interact, they can no longer even be described by their own, independently evolving probabilities, called “pure states.” 

Instead, they become entangled components of a more complicated probability distribution that describes both particles together. It might dictate, for example, that the particles spin in opposite directions. The system as a whole is in a pure state, but the state of each individual particle is “mixed” with that of its acquaintance. The two could travel light-years apart, and the spin of each would remain correlated with that of the other, a feature Albert Einstein famously described as “spooky action at a distance.” 

“Entanglement is in some sense the essence of quantum mechanics,” or the laws governing interactions on the subatomic scale, Brunner said.  This idea of entanglement which first occurred to Seth Lloyd about 30 years ago might explain the arrow of time. Lloyd realized that quantum uncertainty, and the way it spreads as particles become increasingly entangled, could replace human uncertainty in the old classical proofs as the true source of the arrow of time. 

Quantum uncertainty (W. Heisenberg) then gives rise to entanglement, the putative source of the arrow of time. The article related above is most fascinating because of the idea proposed about reality being probabilities. In a sense, the uncertainty element in the probability of a real situation follows John Nash's economic theory concerning what he called the laws of governing dynamics. 

According to Nash, nothing is apparently 'real' until the social interaction in a given interactive event arrives at or comes to a state of equilibrium. He meant that decisions about what to do and when to do it in the realm of economic activity was dependent upon social interaction and the dynamics involved. 

These dynamics are worked out and into a state of equilibrium through entanglement of appearances, language and body language, positioning in view of subordination and domination between those interacting. Once, that was 'worked out' a state of balance is achieved... largely through give/take as between subordination and domination between social actors. 

Their calculating risk/gain realized through their social interaction.  You see, equilibrium does not mean that everything and or everyone is equal. It means to arrive at the best possible outcome for all those involved given that all those involved are both potentially and actually real. This is how we live a social reality. Equality is not achievable, but equilibrium is and equilibrium is possible because of probabilities worked out in a place in space that thus allows time to move forward as a direction as if behaving like an arrow. 

What has to be real is that we the observer acknowledge that we are and we are because something greater than us is observer us. Otherwise, as Niels Bohr pointed, how we could observe. If our being was as uncertain as what we observe, there is nothing certain and nothing to certainly discuss.

Given that, what potential for mankind made known to Him by His Creator. 
What Probability means for social reality - possibility!
