When asked by legendary theoretical physicist Christopher Isham why he had attended graduate school, cosmologist Stephon Alexander answered: "To become a better physicist." As a young student, he could hardly have anticipated Isham's response: "Then stop reading those physics books." Instead, Isham said, Alexander should start listening to his dreams.

This is only the first of the many lessons in Fear of a Black Universe. As Alexander explains, greatness in physics requires transgression, a willingness to reject conventional expectations. He shows why progress happens when some physicists come to think outside the mainstream, and why, as in great jazz, great physics requires a willingness to make things up as one goes along.

Compelling and necessary, Fear of a Black Universe offers us remarkable insight into the art of physics and empowers us all to think big.
