Since its birth in the 1920s, physicists and philosophers have grappled with the bizarre consequences that his theory has for reality, including the fundamental truth that it is impossible to know everything about the world and, in fact, whether it really exists at all when it is not being observed.

Yet more proof that the stuff down at a quantum level makes no sense when thought about using metaphors derived at a human level.
