What is time?It the sort of question we rarely ask because it seems so obvious. And yet, to a physicist, time is simply 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. But in Time Reborn, Lee Smolin disagrees.Recent developments in physics and cosmology point toward the reality of time and the openness of the future. Smolin groundbreaking theory postulates that physical laws can evolve over time and the future is not yet determined. Newton fundamental laws may not remain so fundamental. Time Reborn serves as a popular primer and investigation into time, both what it is and how the true nature of it impacts our world.
