Existence – An Earthly Perspective


Are time and space the same throughout the universe? How did matter and life come to be? How do chance and change create complexity? Does consciousness determine reality? In this course we will explore how we know what we know, and how it has affected our scientific and cultural understanding of existence through history into the present.
