Penguin Putnam
A rising star in theoretical physics offers his awesome vision of our universe and beyond, all beginning with a simple question: Why does time move forward?

Time moves forward, not backward—everyone knows you can’t unscramble an egg. In the hands of one of today’s hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself— a period modern cosmology of which Einstein never dreamed. Increasingly, though, physicists are going out into realms that make the theory of relativity seem like child’s play. Carroll’s scenario is not only elegant, it’s laid out in the same easy-to- understand language that has made his group blog, Cosmic Variance, the most popular physics blog on the Net.

From Eternity to Here uses ideas at the cutting edge of theoretical physics to explore how properties of spacetime before the Big Bang can explain the flow of time we experience in our everyday lives. Carroll suggests that we live in a baby universe, part of a large family of universes in which many of our siblings experience an arrow of time running in the opposite direction. It’s an ambitious, fascinating picture of the universe on an ultra-large scale, one that will captivate fans of popular physics blockbusters like Elegant Universe and A Brief History of Time.

Baker & Taylor
A cofounder of the blog Cosmic Variance outlines a comprehensive vision of the universe that attempts to explain why time moves forward, building on a premise that time owes its existence to conditions before the Big Bang and may be explained by theoretical space-time properties.

Why does time seem to go only one way? And what is time, anyway? A professor of theoretical physics and astrophysics at Caltech, Carroll is well placed to answer these questions, and (luckily for most of us) to do so in language that a non-scientist can understand. In considering the nature of time, he helps readers consider what happened before the Big Bang, and grapple with the question of whether our counterparts in another universe experience time running in a different direction (and, if so, why?). Firmly in the tradition of books by science popularizers such as Carl Sagan or Stephen Hawking, this book by Carroll should have wide appeal. Annotation ©2010 Book News, Inc., Portland, OR (

& Taylor

Uses recent concepts in theoretical physics to explore the properties of spacetime and explain why time appears to only move forward, and has done so since before the Big Bang itself.

Deep analysis requires careful reading. Would have preferred a less detailed presentation... this reads very much like a textbook to me.

Excellent treatment of the arrow of time. Nicely annotated and good bibliography.

The single best treatment of the arrow of time investigation. Must have material for those who have the background to appreciate the different approaches to this FUNDAMENTAL question.
