The article itself isn’t much better:
If space is made of entanglement, then the puzzle of quantum gravity seems much easier to solve: instead of trying to account for the warping of space in a quantum way, space itself emerges out of a fundamentally quantum phenomenon.
- zachf 4y agoI have a PhD in a closely related field and I'm not sure what you mean--this sentence is well-formed and basically correct, if slightly simplified to appeal to laymen.
- wrycoder 4y ago“If space is made of entanglement, then it emerges out of a fundamentally quantum phenomenon.” This makes sense to you?
- zachf 4y agoIts the part that you omitted from your summary that makes the statement nontrivial—the idea that the metric theory (poetically, the warping of space) is only valid as a low energy effective description, and the general case does not have a classical interpretation even in a limit. To put it another way: the quantum theories that are best understood are the ones that are similar to a classical field theory, but that’s not the case here.
- wrycoder 4y agoIt appears that when I eliminated inessential verbiage, what remained was a tautology.
