Richard Brown and Pete Mandik have posted Episode 9 of SpaceTimeMind, "A Journey to the Edge of Hypertime." Here is the episode's capsule-summary:
This is the first of several episodes of the SpaceTimeMind podcast wherein amateur chrononauts Richard Brown and Pete Mandik tackle topics in the physics and metaphysics of time. In this episode, one of the main ideas we kick around is whether any moments exist beyond the present moment. Additionally, we tackle the issue of whether it makes any more sense to say that time flows than it does to say that space moves. If time flows at some rate, must there exist a hypertime relative to which first-order time changes? And is the ensuing infinite regress an intolerable ontic horror? Finally, we discuss the relationship between the phenomenology of time experience and the metaphysics of time by exploring whether a computer simulation of a brain would notice being run backwards in time.
