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…
The Next Revolution
Episode 24 of
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…
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…
- 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;…
Particle or Wave?
In 1923, Louis de Broglie proposed that, like light photons, particles of matter might also display wave properties. The wave nature of smaller particles such as electrons is quite visible and leads to many unusual phenomena, including quantum tunneling mentioned in Lecture 1.
Into the Heart of Matter
With this lecture, you turn from relativity to explore the universe at the smallest scales. By the early 1900s, Ernest Rutherford and colleagues showed that atoms consist of a positively charged nucleus surrounded by negatively charged electrons whirling around it. But Rutherford's model could not explain all the observed phenomena.
The Particle Zoo
Episode 58 of
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.

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.…
