In this 2-disc set and fifth season, Morgan Freeman walks us 'Through the Wormhole' and into the mind-bending realities defining our universe. Exploring topics from gravity to poverty, these ten episodes set out on scientific quests for answers to our most puzzling questions. Is there such a thing as a shadow universe? When did time begin? Is a zombie apocalypse possible? Does the ocean think? Quantum physicists, biologists, statisticians, neuroscientists, and more of the world s greatest minds take a synergistic approach to provide practical answers and pose even more questions in an attempt to explain the unexplained.
