    May I add as a relevant reference:
    Kastner, R. E. On the Status of the Measurement Problem: Recalling the Relativistic Transactional Interpretation

    • I would just note that RTI is not subject to the recent ‘no-go’ proofs since it does not assert that quantum states are universally applicable; rather it has a natural limiting criterion for the applicability of quantum states. It particular, neither the Geiger counter nor the cat nor Wigner nor his friend (understood as spacetime-locatable objects) are described by quantum states.
