In quantum physics. There is a concept of action at a distance. I had my doubts when I first encountered it 50 years ago. And I have waited to see a reliable test based on significant distances.
Action at a distance deals with two atomic particles that are paired. Each has a spin that is the opposite of the other. The math in quantum physics says that regardless of distance, that the spin of one, when it is known, determines the spin of the other. Since the equation doesn't include distance this action is assumed to occur in the universe, even though each atomic particle may be at the opposite end of a galaxy.
Something like that helps explain the strange phenomenon that the hatred of Jews on a smidgen of land called Gaza transmits its hatred of Jews to me in San Francisco.
The distance doesn't seem to matter. Wherever I detect Jew hatred in Gaza or among my Facebook friends. I take the opposite direction. I removed those people from Facebook and from my life and make sure that they stay removed. I eliminated five friends on Facebook and have made certain I will not go to Gaza under any future circumstances.
Note to Israel. See how the world works in my: social sorting. The decent people long ago left Gaza. Only the monsters remain. This will keep happening in each new generation.
Not quantum action at a distance but a connection worth noting.
