In this chapter, the relativistic transactional interpretation (RTI) is shown to completely nullify the Maudlin objection (a type of contingent absorber experiment) to the original, nonrelativistic TI. RTI is applied to some prominent quantum “paradoxes” such as the quantum eraser and the Frauchiger–Renner paradox and shown to resolve these. In addition, RTI derives standard decoherence results while also providing an account of concrete measurement outcomes that is missing in standard (unitary-only) decoherence theory.
