What's it all about? is four-part series co-presented by Colette Kinsella and Sean Duke that will explore some of the wonderful mysteries of science. Together with some of the brightest and finest thinkers; the presenters will investigate the inner workings of our incredible brains, search for ET, get to grips with consciousness, and consider whether anything awaits us after death. We speak to scientists whose passion for their subject transforms them into great storytellers. We will also speak to people whose lives have been affected by science, and learn about how science is dramatically impacting all our lives.
