Last year, the Nobel Prize in physics was awarded to three physicists who allegedly found that the universe is not locally real. But what does this mean? What are the two types of non-locality? And what did Einstein’s have to do with it? That’s what we’ll talk about today. Some examples for models that violate measurement independence are here: C. H.
