Theoretical cosmologist, Sean Carroll

On today’s ETFF, Sean Carroll will discuss with us the nature of time and space, and some of the newest ideas in modern theoretical cosmology and physics. He will also discuss time travel, the god hypothesis, and the origins of the universe.

Carroll works at Caltech in Pasadena, California. He does research on theoretical aspects of cosmology, field theory, gravitation, and quantum mechanics as well as work on dark matter and dark energy, modified gravity, topological defects, extra dimensions, and violations of fundamental symmetries. Carroll has written a couple of popular-level books: ‘From Eternity to Here: The Quest for the Ultimate Theory of Time’, and ‘The Particle at the End of the Universe: How the Hunt for the Higgs Boson Leads Us to the Edge of a New World.’

We are a culture besieged by violence. Everyday we hear stories of mass shootings or stabbings, of a rising violent crime rate, of vigilantism, and we have been marred in one war or another since the birth of this nation… resulting in the maiming or killing of millions (usually far less Americans than those we target).

When peace activists, humanists, or even average citizens – tired of all the violence and war – try to speak out against the insanity, we are told human beings are violent by nature.  We are shown right-leaning works of social science which prove our bloody history to be the norm, not an anomaly, and told it goes back 50,000 years or more. We are told that war is either in our genes, or even something which is needed for homo sapien sapien to have balance in our societies. Even those who admit “war is hell” are pretty sure it is also inevitable; consequently they, and many in our society, feel those of us looking toward a peaceful, egalitarian, humanistic society without warfare are utopians living in a reality of our own inception… peaceniks left over from the radical 60s who have not grown up and who would be better served trying to help others within our current, often dysfunctional society, rather than demand another kind of world…

But what are humans REALLY like? What does the science ACTUALLY say? We will be speaking with evolutionary anthropologist Douglas Fry and psychologist Darcia Narvaez about these questions and more on the next edition of Equal Time for Freethought!

Theoretical Physicist, Brian Greene

Our guest this week is Brian Greene, a string theorist and theoretical physicist with a lengthy resume. Known as a science popularizer, he is the author of four books including ‘The Fabric of the Cosmos’ and ‘The Elegant Universe’, both of which became PBS specials that he hosted. He is co-founder and current Board Chairman of the World Science Festival, co-founder of the new and free online series of science courses at World Science and a professor of physics and mathematics at Columbia University. We will be discussing his work and how best to communicate science to the general public.
