>> This is an alternative to the concept of instantaneous, or "non-local" action at a distance.
Notice the word "alternative", instantaneous action at a distance is a concept that was suggested at one point in the development of physics and discarded once relativity was figured out. Action at a distance these days is always at the speed of light.
> So, as you acknowledge, zero information about your hand has gone much distance from the earth.
No, not zero. All the gravity from the atoms in my hand is already out there.
> Someone 1000 light years away who could resolve gravitational information into an image with perfect detail wouldn't be able to perceive your hand, you, or anything related.
Correct, they would see the location of the atoms that make up my hand today, as those atoms looked 1000 years ago. (Probably in plants, and water.)
But remember: They do see the gravity from those atoms!!! Meaning the gravitational force my hand exerts, already exists 1000 years away, just in a different shape.
> Because gravity isn't a non-local force.
Are you saying gravity is a local force? Because that's not true.
