The Biggest Ideas in the Universe: Space, Time, and Motion is a nonfiction book by American theoretical physicist Sean M.

The Biggest Ideas in the Universe: Space, Time, and Motion is the first volume in an ambitious trilogy that seeks to explain physics to a popular audience—one willing to grapple with the basics of calculus and other mathematical underpinnings of the field.

This book focuses on classical mechanics, including Einstein's theory of relativity..."[4] Kirkus Reviews commented, "The author is at his best with familiar concepts such as space.

Once considered an empty container for the universe, it turns out to be a turbulent phenomenon with “a life of its own.” Time is similar to space; it's part of how we locate ourselves, and we can measure it.

Gravity, energy, relativity, and the life of stars receive Carroll's enthusiastic attention, much as they did in such previous books as From Eternity to Here and Something Deeply Hidden.
