On this special episode of Going Underground, we speak to Professor Brian Greene, string theory pioneer and author of 'Until the End of Time: Mind, Matter and Our Search for Meaning in an Evolving Universe.' He discusses the concept of entropy, where the universe tends to go from order to disorder, what this means for our existence as humans and the solar system around us, what the end of the universe will look like, why humans evolved to develop complex languages and the debate surrounding the subject, the development of quantum physics, the origins of religion, our response to coronavirus, and more!
