geordief Posted September 29, 2017 Share Posted September 29, 2017 I think I am right to say that the causative mechanism between the two phenomena has not yet been uncovered . Rather than ask what it might be ,can I ask what main theories have been discounted? Does all ongoing research into this area require some kind of input from quantum theory or are there any purely classical theories that are also being pursued ?(I hoped I have not mangled the terminology with my use of the term "theories") Link to comment Share on other sites More sharing options...
mathematic Posted September 29, 2017 Share Posted September 29, 2017 Relativity theory is considered a classical theory. Some unification attempts to make it a quantum theory. Link to comment Share on other sites More sharing options...
geordief Posted September 29, 2017 Author Share Posted September 29, 2017 I came across this recently https://phys.org/news/2017-09-entanglement-inevitable-feature-reality.html#jCp "Entanglement is an inevitable feature of reality" where they seem to be working backwards from classical behaviour to put restrictions on any possible quantum theory that might be possible.. I see no specific mention of spacetime curvature in that article(which does not go into what it says is a very complicated proof in the paper) ..... So not sure if it is relevant to the OP.

mathematic Posted September 30, 2017 Share Posted September 30, 2017 The article is irrelevant. Try this to get some idea. https://en.wikipedia.org/wiki/Quantum_gravity Link to comment Share on other sites More sharing options...
