What is time? It's the sort of question we rarely ask because it seems so obvious, yet to most physicists, time is a human construct and an illusion; if you could somehow get outside the universe and observe it from there, you would see that every moment has always existed and always will. Theoretical physicist Lee Smolin disagrees, and in this popular primer and investigation of time, he explains why. Recent developments in physics and cosmology point toward the reality of time and the openness of the future—Newton's fundamental laws may not remain so fundamental, argues Smolin, and his groundbreaking theory postulates that physical laws can actually evolve over time.
"If you are looking for a bracing alternative vision of physics built from the ground up, Smolin's Time Reborn will take you to the mountaintop."—NPR
