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…
Final Frontier? - Guide to the Universe
Part of the Series: Horizon
Over the last 40 years, Horizon has joined scientists as they have probed the secrets of the universe - from the origin of dark matter to the nature of gravity and even stealing a glimpse into the private life of a black hole. Dallas Campbell delves into the Horizon archive…
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…
The Next Revolution
Survey the greatest unsolved problem in theoretical physics: the search for a quantum theory of gravity. Examine string theory, loop quantum gravity, and also entropic gravity, which suggests a revolutionary link with thermodynamics. Close the course with a deepened appreciation for the connection between everyday features of gravity and the…
Black Holes, Tides, and Curved Spacetime - Understanding Gravity Course
Gravity rules the universe. Without it, everything would dissolve into a gas of randomly interacting atoms. Yet gravity is one of the least understood forces in nature. Black Holes, Tides, and Curved Spacetime introduces you to key ideas in gravity research over the past 400 years. It's an awe-inspiring journey…
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…
Inexplicable Physics
Turn now to some inexplicable aspects of physics and our physical world. Among the many eye-opening topics you'll learn about in this episode are the discovery of more and more elements on the periodic table; muon neutrinos, tao particles, and the three regimes of matter; the secrets of string theory;…
The Particle Zoo
By 1960 a myriad of seeming elementary particles had been discovered. Survey the standard model that restored order to this subatomic chaos, describing a universe whose fundamental particles include six quarks; the electron and two heavier cousins; elusive neutrinos; and force-carrying particles such as the photon.
Galileo - The Challenge of Reason
This dramatic production presents Galileo (Douglas Watson), challenger of traditional views of astronomy and physics, whose conflicts with established beliefs led to his trial as a heretic in 1632, but whose theories came to dominate Western thought in succeeding centuries. An LCA release. Columbus Film Festival
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.…
Exoplanets and Extraterrestrial Life
Episode 28 of Redefining Reality
Fiction writers have led the way in exploring the prospects of life beyond Earth. See how scientists are catching up, looking for extraterrestrial organisms using a variety of ingenious techniques. Learn how they are narrowing the search and which tantalizing clues have already turned up.
The Strangest Force
Begin your exploration of gravity with Isaac Newton and the famous story of the apple. Why was it such a breakthrough to connect a falling apple with the faraway moon? Review the essential characteristics of gravity and learn why small asteroids and large planets have such different shapes.
