The Universe's Hidden Dimensions

When Harvard physics professor Lisa Randall tried to tackle some of the most fundamental questions of her field, she ran into a problem.

Doctor Randall found that the answers to many of those questions lie beyond our traditional view of the universe. In fact, they may lie beyond a universe we can even comprehend.

In her new book, "Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions" she theorizes that the universe cannot be explained without radically changing how we see it.

Randall theorizes that there may be extra dimensions beyond length, width, and height and the fourth dimension of time that we see and experience in the world every day.

Randall discussed new dimensions with Bob Oakes.
