Overview

What forces molded the universe? Are those forces still at work? Discover the answers to these and other startling questions about the cosmos with My Favorite Universe. Dr. Neil deGrasse Tyson's course is a spirited and intellectually engaging journey through our universe and its history, from before the big bang to the likely ways in which Earth-and perhaps the entire universe-might end. Explore how black holes are formed; how asteroids move through space; why the odds seem overwhelmingly in favor of extraterrestrial life; and much more. With the foundation provided by this magnificent course, the realities of the universe will be revealed in stark-and often violent-beauty.

About

Neil deGrasse Tyson

Of all the amazing things about the Universe, I think two stand above all the rest. One of them is that we know so much about the universe, but another is that there's even more that we don't know.

INSTITUTION

Hayden Planetarium

Dr. Neil deGrasse Tyson is the Frederick P. Rose Director of the Hayden Planetarium at the American Museum of Natural History in New York. He is also a research associate in the Department of Astrophysics at the museum. Professor Tyson earned his undergraduate degree in Physics from Harvard University and his Ph.D. in Astrophysics from Columbia University. Dr. Tyson has written prolifically for the public, including a series of essays in Natural History magazine on which his previous Great Course, My Favorite Universe, is based. His books include Space Chronicles: Facing the Ultimate Frontier; a memoir, The Sky is Not the Limit: Adventures of an Urban Astrophysicist; and One Universe: At Home in the Cosmos (coauthored with Charles Liu and Robert Irion), winner of the 2001 American Institute of Physics Science Writing Award to a Scientist. Dr. Tyson is host of The Cosmos, a science documentary series televised on the Fox network, and former host of the PBS television series NOVA scienceNOW. His contributions to the public appreciation of the cosmos have been recognized by the International Astronomical Union in their official naming of asteroid "13123 Tyson."

On Being Round

01: On Being Round

What forces tend to make objects round? And why is a sphere the most efficient shape an object can take? The answers will lead us across the cosmos.

35 min
On Being Rarefied

02: On Being Rarefied

Just how "thin"-low in density-is the "thin air" out of which a magician produces a rabbit? And if the universe contains components that are even thinner, exactly what does that mean to us?

31 min
On Being Dense

03: On Being Dense

This is a discussion of different levels of density and the inherent mysteries of this property, along with the ways in which an understanding of density helps us think creatively about the world.

32 min
Death by Black Hole

04: Death by Black Hole

Take a look at black holes, one of the most fascinating topics in the universe-including the ways in which they would kill a human being, how they wreak havoc in the universe, and some provocative new research.

31 min
Ends of the World

05: Ends of the World

Here is a detailed look at three scenarios for the destruction of our planet: the death of the Sun, the collision of the Milky Way and Andromeda galaxies, and the heat death of the cosmos.

Coming Attractions

06: Coming Attractions

We now know that a deposit of energy sufficient to kill off 50 to 90 percent of all species strikes Earth every 100 million years. This lecture looks at our risks of getting hit by an asteroid and what we can do to avoid it.

32 min
Onward to the Edge

07: Onward to the Edge

Take a break from the death and destruction of asteroids and the end of the universe and wonder, instead, at the enormity of the cosmos and what our place in it might be.

31 min
In Defense of the Big Bang

08: In Defense of the Big Bang

We now know without doubt how the universe began, how it evolved, and how it will end. This lecture explains and defends a "theory" far too often misunderstood.

34 min
The Greatest Story Ever Told

09: The Greatest Story Ever Told

A synthesis of the greatest discoveries of physics, astrophysics, chemistry, and biology creates a coherent story of the birth and evolution of the cosmos.

31 min
Forged in the Stars

10: Forged in the Stars

The origin of the elements that make up life is one of the most important discoveries in any field in the 20th century, yet underappreciated by the public because it happened over many decades. This lecture presents a step-by-step explanation of the long path to a Nobel Prize-winning idea.

31 min
The Search for Planets

11: The Search for Planets

Before 1995, the planets of our own solar system were the only ones we knew about; the total has now passed 100. This lecture discusses the tools and methods being used to find other planets that might be hospitable to human life.

33 min
The Search for Life in the Universe

12: The Search for Life in the Universe

This lecture examines the very real possibility that life exists elsewhere, and speculates about its origins and chemical makeup.
