This has very little to do with the modern issue of action at a distance vis a vis entanglement, and everything to do with the prevailing belief in an aether during Newton’s time. Einstein meanwhile, was actually commenting on entanglement physics.
- daxfohl 8y agoYeah I'm not trying to imply they're the same physical cause, just the same philosophical perception of ickiness. How to phrase better? Newton had issues with aether messing philosophically with local realism. Einstein fixed that through SR and then GR. But then QM introduced new problems with local realism, and maybe the next physics revolution is reconciling that problem. So, not the same thing, but perhaps two different sides of the same million-sided armchair-philosophical dice.

Newton wrote, "It is inconceivable that inanimate Matter should, without the Mediation of something else, which is not material, operate upon, and affect other matter without mutual Contact." Einstein wrote, "I cannot seriously believe in it because the theory cannot be reconciled with the idea that physics should represent a reality in time and space, free from spooky actions at a distance." Newton was talking about gravity, Einstein about entanglement. But the objection is essentially the same one. That's the reason that Newton's quote above is included in an article on the principle of locality.
- DmenshunlAnlsis 8y agoEinstein was talking about violations of his theory, namely the velocity limitation imposed, Newton was concerned with a medium. They are utterly different. Maybe they sound similar without any knowledge of the underlying theories, or just take quotes out of context, but it’s a very superficial similarity.
