Wave particle duality is FALSE in my world. See my humorous 6 minute video: a psychiatrist’s view of Quantum Mechanics. What is wave particle duality? You have something that when you look at it one way is a wave; another way, it acts like a particle. But if the wave and particle were traveling in opposite directions, then if you looked at it one way it would be a wave, another way, it act like a particle. But they couldn’t be two aspects of the same thing because they travel in opposite directions.
