Is time travel possible? What does it mean to say the universe is fine-tuned? Could our universe be fake? Or, if it is real, is it part of a multiverse? In an attempt to solve such mysteries, leading experts attempt to break the world down to its smallest particles and build it back up - to understand the universe by understanding the atom. In this compelling audio course, Dr. Robert Lawrence Kuhn, creator and host of the PBS series Closer to Truth, examines the riddles of the universe with 13 luminaries in physics, cosmology, astronomy, philosophy, mathematics, and chemistry.

Is there other intelligent life in the universe, or are we all alone? Now you can explore this question through 17 compelling conversations with leading experts on extraterrestrial life. The prospect of alien intelligences has long captivated cosmologists, perplexed theologians, and provided rich fodder for science fiction writers. While we may doubt that the large-eyed, green-skinned figures of sci-fi films will one day descend to Earth in UFOs, it is far harder to reject wholesale the possibility that intelligent life - in some form yet unknown - exists.

How did our universe begin, and when and how will it end? Is the universe infinitely expanding, as the theory of cosmic inflation insists? If alien life exists, what are the chances of our encountering it, and what would such an encounter mean for humanity? Now, you can sit in on conversations with the world’s leading cosmology experts as they answer these and many other fascinating questions.

There is little more humbling than contemplating the magnitude of the known universe. That is, until you consider the possibility of worlds beyond that universe. Join Dr. Robert Lawrence Kuhn, celebrated author and host of the hit PBS series Closer to Truth, as he probes the limits of the cosmos with 15 luminaries in astrophysics, cosmology, and astronomy. The series begins with explorations of the universe’s boundaries.
