Finally, someone else pointing out that "Obamacare" was always the Republicans' own plan, all along. This young, democratic Congressman lays it out so clearly that even a Fox-watcher would understand. And start scratching his head asking: "So what was all the screaming about? And why did I ever watch Fox?"

Proposed Equivalency Between Wormholes & Entanglement
The quantum source of space-time: http://www.nature.com/news/the-quantum-source-of-space-time-1.18797

I included this article in the most recent Digest but wanted to revisit it for those who missed it because I find it fascinating. At heart this concerns the pursuit to unite the incompatible fundamental theories of quantum mechanics and general relativity, and specifically the attempt to cast quantum entanglement as the fundamental basis of geometry and a defining feature of spacetime and the geometric gravity described by relativity. While not yet proven the approach seems elegant from a number of different angles, tying together concepts from holographic Universe theories, anti-de Sitter spaces & boundary membrane equivalences, tensor networks, and quantum error-correcting codes. 

When the entanglement between two regions in the model is reduced the areas pull apart, and when it reaches zero the regions split off entirely, suggesting that entanglement is necessary for space to exist. Examining the relationship from a different angle suggests that a wormhole connection between two regions and an entanglement connection between two regions are the same thing but on a vastly different scale. They are different ways of describing the same underlying reality. 

Much theoretical development is still needed: while the relationships and connections are tantalising the models still do not accurately describe major features of the Universe we seem to find ourselves in and most lacking of all is an adequate treatment of that most fundamental of things: time. 

One question I have arises from considering that this approach stems from a foundation of quantum theory to derive the equivalences as part of the large theoretical field of quantum gravity. But I wonder if others could approach the same phenomena from a foundation of general relativity to derive the same equivalences? Might this also be a fruitful line of inquiry, to treat entangled particles as mini wormhole connections and thus build particle physics up from there?

The far side of the moon, illuminated by the sun, is seen as it crosses between our 'EPIC' camera on the Deep Space Climate Observatory (DSCOVR) satellite, and the Earth - one million miles away. Check it out: http://go.nasa.gov/1Dq0IOh #EarthRightNow
