Einstein Podolsky Rosen Paradox Resolved By Local Modal Realism

leave a comment »

The Many Worlds Wiener Sausage is a very simple model that shows how the apparent non-locality in the infamous Einstein-Podolsky-Rosen paradox can arise simply by the world splitting into parallel universes. It can be understood by advanced high school students. But we saw that although it is a many worldsmodel, it is not a quantum world! Today we will make the model look like the great spaghetti monster. There are two aspects about this that I find amazing:

1) It can still be understood by high school students but is nevertheless correct quantum mechanics – not some cracked pot’s hidden variables nonsense.

2) It is one single and natural step that turns the model quantum, and this step has two important features:

– The step is obviously a local modification at one certain place of a classical and thus fundamentally local model, therefore the quantum model also still obeys Einstein locality! Since quantum physics cannot be both local and real, the “real” must have been modified. And it has.

– The crucial step obviously turns something that still can be described as a naïve direct realism into something that can no longer be so described, and again, not via philosophical sophistry or advanced math that rests more on authority than on what lay people can understand: After the crucial modification, a little arrow called “DirectlyReal”, short “DR”, is no longer able to point to the one real world it pointed to before….
