Ruth Kastner, a physicist turned philosopher known for her work on the transactional interpretation of quantum mechanics, explores fascinating ideas around retrocausality and the measurement problem. She advocates for a paradigm shift in physics, encouraging a deeper understanding of quantum phenomena. The discussion dives into the distinctions between observers and measurers, the role of consciousness in measurements, and the potential for retrocausality to reshape our perception of time. Kastner also critiques traditional views and calls for more nuanced thinking in scientific inquiry.
