"The Evolving Block Universe and the Cosmological Emergence of Time"

Time as given by physics does not match our conscious experience. This has led leading cosmologist George Ellis to propose the Evolving Block Universe model where spacetime continuously emerges. This seminar will look at some principal problems with Ellis’ model, especially how the present moment and the passage of time are defined.
