Inexplicable Life
Join Professor Tyson on a fascinating investigation of the possible origins of life in the universe. Why was Jupiter believed to be a good environment for life in the 17th century? Why is there only one single "tree of life" on Earth instead of multiple ones? Could life have come…
History's Mysteries
Begin this journey by taking a closer look at concepts that were once unexplainable but are now better understood. You'll focus on two such former mysteries: the existence of an invisible "aether" through which light and sound were believed to travel and the orbit of Mercury, which seemed to violate…
Why Time Is a Mystery
Begin your study of the physics of time with these questions: What is a clock? What does it mean to say that "time passes"? What is the "arrow of time"? Then look at the concept of entropy and how it holds the key to the one-way direction of time in…
Time Travel
Use a simple analogy to understand how a time machine might work. Unlike movie scenarios featuring dematerializing and rematerializing, a real time machine would be a spaceship that moves through all the intervening points between two locations in spacetime. Also explore paradoxes of time travel.
The End of Time
Peter Mettler's enthralling, mind-bending new documentary is a tour de force that challenges our conception of time - and perhaps the very fabric of our existence. With stunning cinematography and a knack for capturing astonishing moments, The End of Time travels the planet - from the CERN particle accelerator outside…
Making Stuff Faster
Part of the Series: NOVA - Making More Stuff
Ever since humans stood on two feet we have had the basic urge to go faster. But are there physical limits to how fast we can go? David Pogue wants to find out, and in Making Stuff Faster, he'll investigate everything from electric muscle cars and the America's cup sailboat…
Alien Planets Revealed
Part of the Series: NOVA
It's a golden age for planet hunters: NASA's Kepler mission has identified more than 3,500 potential planets orbiting stars beyond our Sun. Some of them, like a planet called Kepler-22b, might even be able to harbor life. How did we come upon this distant planet? Combining startling animation with input…
Inexplicable Space
Shoot off into the stars for an investigation of some perplexing aspects of space that science has uncovered in the last half-century. Learn about the mysterious trajectory of the Pioneer spacecraft (known as the "Pioneer anomaly"). Explore two of the longest-standing problems in modern astrophysics: dark matter and dark energy.…
Inexplicable Cosmology
Brace yourself for a fascinating trip through dimensions higher than our own. You'll discover how quantum physics and string theory have opened our eyes to the possibilities of quantum foam, the multiverse, and antimatter. Join Professor Tyson for a preview of the fate of the universe (including the collision of…
The Internet and Virtual Reality
Episode 35 of Redefining Reality
For all of their ubiquity, personal computers, email, and the Internet represent a major departure in the evolution of computer technology. Witness the exciting and improbable birth of personal computing in the 1970s, and explore the nature of the virtual world where more and more people now reside.
The Science of Healing
PBS
The Science of Healing follows Dr. Sternberg to a tiny village in Greece, where her personal experience of the power of place in healing inspired the research that led to this program. We join her as she explores ruins of ancient Greek healing temples, and visits cutting edge science labs…
Ancient Computer
Part of the Series: NOVA
In 1900, a storm blew a boatload of sponge divers off course and forced them to take shelter by the tiny Mediterranean island of Antikythera. Diving the next day, they discovered a 2,000 year-old Greek shipwreck. Among the ship's cargo they hauled up was an unimpressive green lump of corroded…
