Ruth Kastner joins Curt Jaimungal to discuss her transactional interpretation (TI) of quantum mechanics, addressing the measurement problem, retrocausality, and the integration of quantum mechanics and gravity. Kastner advocates for a paradigm shift in physics, urging researchers to embrace complexity and nuance in understanding quantum phenomena and reality.
