Making Sense of Quantum Superposition

In previous work, a new interpretation of spacetime diagrams has been presented. That new interpretation would define some spacetime areas where superposition seems to exist. Applied to the Einstein-Podolsky-Rosen paradox, locality would be back despite the observations of entanglement. This work also leads to the idea that superposition can only exist for the wave, but the particle should have a single position. Two new experiments are proposed, the first one is a new test for entanglement, the second would explore the link wave-particle and the complementarity principle.
