Time as a Non-Fundamental Property
The podcast discusses the idea that time may not be a fundamental property of the physical world. It distinguishes between three common properties of time - the special present moment, the flow or passage of time, and the fundamental direction of time. According to the guest, these properties may not be part of physics, as they are subjective experiences. He suggests that time can be understood within the framework of a four-dimensional block universe, where time is just part of spacetime. The notion of causation is also seen as subjective and dependent on our temporal perspectives as agents.
