Entanglement and the Geometry of Spacetime

Theorists have forged a connection between wormholes in spacetime (above) and a quantum phenomenon called entanglement.

But how big an insight is this? It depends on whom you ask. Susskind and Maldacena note that in both papers, the original quantum particles reside in a space without gravity. In a simplified, gravity-free 3D model of our world, there can’t be any black holes or wormholes, Susskind adds, so the connection to a wormhole in a higher dimensional space is mere mathematical analogy. The wormhole and entanglement equivalence “only makes sense in a theory with gravity,” Susskind says. However, Karch and colleagues say that their calculations are an important first step toward verifying Maldacena and Susskind’s theory. Their toy model without gravity, Karch says, “gives a concrete realization of the idea that wormhole geometry and entanglement can be different manifestations of the same physical reality."A Link Between Wormholes and Quantum Entanglement

Note here about Issuu software in link above. I made a comment about this type of software with regard to document writing and appearance. For an open publishing format I am less then pleased that if you have a shared format and embedding program that allows you to embed articles and then does not do this, to me,  if you go a bit further into the program of Issuu then it's no more then a publishing ploy to get you to pay money for use of this type of publishing format. So while I started to use this program for document sharing I had to only provide the link to an interesting article to the ongoing saga of Maldacena and Susskind. I had to also substitute the main article by Maldacena,  with news story
