A Link Between Wormholes and Quantum Entanglement

sciencehabit writes "Theoretical physicists have forged a connection between the concept of entanglement — itself a mysterious quantum mechanical connection between two widely separated particles — and that of a wormhole — a hypothetical connection between black holes that serves as a shortcut through space (first abstract, second abstract). The insight could help physicists reconcile quantum mechanics and Einstein's general theory of relativity, perhaps the grandest goal in theoretical physics."

Re:Mysterious quantum mechanical connection?

Unfortunately, it's not that simple. In the scenario you're describing, there is hidden information inside the envelopes, as the direction of the cards has already been determined. The quantum mechanical analog is this is so-called "hidden variables", aspects of the state of a system that we simply can't see. But experiments have ruled out [wikipedia.org] this possibility, so quantum mechanics is actually much weirder than that.

Alternatively, superdeterminism.

Well, it doesn't match what we actually observe. And I'm not discounting here that there could be the possibility of an observer, say one external to our universe, for who superdeterminism is observed and for which there could be local hidden variables. But we're not in that chair and so that theory would not apply to us.
