= Quantum particles take all possible paths
As mentioned at: https://physics.stackexchange.com/questions/212726/a-quantum-particle-moving-from-a-to-b-will-take-every-possible-path-from-a-to-b/212790#212790[], classical <gravity waves> for example also "take all possible paths". This is just what waves look like they are doing.
