In this 2-disc set and fifth season, Morgan Freeman walks us "Through The Wormhole" and into the mind-bending inquiries of the realities defining our universe. Exploring topics from gravity to poverty, these ten episodes set out on scientific quests for the long-sought answers to man's most puzzling questions. Does the ocean think? Is a zombie apocalypse possible? Is there such thing as a shadow universe? And just when did time begin? 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.
