Reverse Causality and the Transactional Interpretation
... The simple answer is “No!”. It is the formalism of quantum mechanics that makes all of the testable predictions. As long as an interpretation like the TI is consistent with the formalism, it will make the same predictions as any other valid interpretation, and no experimental tests are possible. ...
