Quantum mechanics is well known for its strangeness and may not only control the movement of subatomic particles but could also shape what it means to have any experience at all. In this episode, Kate explores the provocative idea that consciousness might arise from the unpredictable, entangled world of quantum physics rather than from the simple computations of the classical brain. Is it possible that our minds owe their existence to quantum events rather than just neural circuits?
Kate guides listeners through influential theories of quantum consciousness, the skepticism they face, and the ongoing experiments that could reveal the mind's deepest origins. With discussions that range from Penrose and Hameroff's orchestrated objective reduction to the speculation that consciousness is woven into the structure of spacetime itself, this episode challenges listeners to rethink what it means to be conscious.
"Quantum mechanics is weird. Consciousness is weird.
But weird plus weird doesn't equal explained." ~Kate
