Physicists Conduct The Most Massive Test Ever of The #Einstein-#Podolsky-#Rosen Paradox :
"Our results represent the first observation of the #EPR paradox with spatially separated, massive many-particle systems," the researchers write in their paper.
"They show that the #conflict between #quantum #mechanics and #local #realism does not disappear as the system size increases to more than a thousand massive particles."
