In this podcast episode, physicist Dr. Brian Greene explores intriguing themes related to time, entropy, and quantum mechanics, shedding light on their effects on consciousness and free will. The conversation examines the abstract nature of time, its ties to entropy, the universe's expansion, and the unpredictable behavior of particles at the quantum level. It also addresses the philosophical debates surrounding determinism and free will in the context of quantum uncertainty, while introducing string theory as a potential unifying framework in physics. By unraveling these complex ideas, the episode reveals how our understanding of the physical universe shapes our sense of self and our society.
