The Cramer interpretation excludes the foggy neither/both possibilities. Since Feynman models show that quantum interactions are a conjunction of particles shaking hands with virtual emissions going both forward and back in time (as an antiphoton is merely a photon traveling backward in time) which reinforce each other to create real particles transmitted between, and cancelling out virtual emissions outside the handshake by destructive interference, that there is never a state of indecision. The cat is always either alive or dead. The two possible choices are not both made (thus creating two parallel universes) only one choice is made, so there is only ONE universe resulting from a quantum interaction, so multi-verse theory is bunk.
