Course Overview

Tyson iPad

Popular astrophysicist and Director of the Hayden Planetarium Neil deGrasse Tyson is renowned throughout the scientific community and the media for his vast knowledge, penetrating insights, and amazing ability to make even the most intimidating areas of science accessible and enjoyable. Now, with The Inexplicable Universe: Unsolved Mysteries, you can join him for an edge-of-your-seat journey to the frontiers of the known (and unknown) universe.

Each of these six highly visual episodes introduces you to profound questions being addressed by the world’s top scientists. You’ll learn about staggering concepts such as quantum foam, dark matter, and dark energy; contemplate traveling through a black hole; probe the existence of multiple universes; consider whether time travel is possible; and much, much more.

6 Episodes (31 Minutes Each)

  1. History’s Mysteries

    Take a closer look at mysteries of physics that were once unexplainable but, thanks to quantum physics, are now better understood.

  2. The Spooky Universe

    Delve into mind-warping physics concepts such as time dilation and quantum tunneling.

  3. Inexplicable Life

    Delve into mind-warping physics concepts such as time dilation and quantum tunneling.

  4. Inexplicable Physics

    Examine the periodic table of elements, subatomic particles, string theory, and black holes.

  5. Inexplicable Space

    Uncover two of the greatest mysteries in astrophysics—dark matter and dark energy—and map the shape of spacetime.

  6. Inexplicable Cosmology

    Explore truly exotic concepts like quantum foam, the multiverse, multiple dimensions, and the likely fate of the universe.

Lots of good stuff packed into 6 lectures

With his inimitable style and wit, Professor Tyson covers a variety of topics including the basics of general relativity, string theory, wormholes, and the origin of the word "quark" in particle theory. He makes difficult concepts easy to understand. The visuals for the course are also more appealing - the set for his lectures is a living room with white leather chairs and a telescope, rather than the usual brick wall and podium. Great primer for basic astronomy, physics and cosmology....Or if you've just wondered about the fundamentals of the world we live in...

Thought provoking science fundamentals

If you already have a solid base of scientific knowledge and are solely looking to increase the depth of your knowledge then this is NOT the course for you.

However, this IS the course for you if you fall into one of these two categories:

1) You are a scientific neophyte and want a short, entertaining synopsis of some of the key ideas of science.

2) You already have a good understanding of scientific basics but want to see them couched in novel, thought provoking ways.

Dr. Tyson’s presentations on the origin of life; the possibilities regarding interactions between humanity of extra-terrestrial life; the perception of time as viewed from the perspective of a photon; and how the evolution of the cosmos will gradually render pieces of the cosmological puzzle out of view are particularly insightful.
