The theory is the maths. Maths makes predictions, observation confirms those predictions. End of story. Local hidden variables are not required any more than a medium is required for an electro magnetic wave to propagate. And yes, it's correct that entanglement transfers no information! So there's nothing spooky about it; or more correctly it might seem spooky but there's no action at a distance.
