Stephen Hawking, Carl Sagan and Arthur C. Clarke share their thoughts on a number of topics including the Big Bang Theory, the expansion of the universe, black holes, extraterrestrial life and the origins of creativity.

"Have you ever wanted to travel to the edge of the universe? What about getting sucked up into a black hole? For fans of Astrophysics for People in a Hurry comes an accessible science narrative that invites readers to eavesdrop on a conversation between two scientists as they dive into a multidisciplinary discussion of our understanding of the universe. Explore the depths of our universe, both known and unknown, with two award-winning physicists,...

Highlights the many ways we are all linked to the world around us.

Seven episodes of the television program about the universe and its mysteries. These episodes focus on the solar system.

A groundbreaking guide to the universe and how our latest deep-space discoveries are forcing us to revisit what we know and what we don't. This is the first book to address what will be an epoch-defining scientific paradigm shift. Stuart Clark will ask if Newton's famous laws of gravity need to be rewritten; if dark matter and dark energy are just celestial phantoms? Can we ever know what happened before the Big Bang? What's at the bottom of a black...

Over the past few decades, a handful of scientists have been racing to explain a disturbing aspect of our universe: only four percent of it consists of the matter that makes up you, me, our books, and every star and planet. The rest is completely unknown. Richard Panek tells the dramatic story of the quest to find this “dark” matter and an even more bizarre substance called “dark energy.” This is perhaps the greatest mystery in all of science,...

"If Ms. Frizzle were a physics student of Stephen Hawking, she might have written THE UNIVERSE IN YOUR HAND, a wild tour through the reaches of time and space, from the interior of a proton to the Big Bang to the rough suburbs of a black hole. It's friendly, excitable, erudite, and cosmic." -Jordan Ellenberg, New York Times besteselling author of How Not To Be Wrong Quantum physics, black holes, string theory, the Big Bang, dark matter, dark energy,...

"Stephen Hawking's closest collaborator offers the intellectual superstar's final thoughts on the cosmos--a dramatic revision of the theory that made him the heir to Einstein's legacy. Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. Pondering this mystery led Hawking to study the big bang origin of the universe, but his early...
