5.0 out of 5 stars A new, non-mystical, way of thinking about universe by an experienced and expert physicist/cosmologist., 22 Jun. 2013
Verified Purchase(What is this?)
This review is from: Time Reborn: From the Crisis in Physics to the Future of the Universe (Kindle Edition)
The way time is mystified in modern physics and cosmology baffles me. In my view the nature of time is simple. Things move. Agreed? Time is a measurement that compares the movement of one thing, A, to another, B, a reference object that we assume moves in a repetitively regular fashion, e.g. the sun, a pendulum, a caesium atom.

Time is real but dependant. There is a good analogy with temperature or smell. Temperature would not exist if objects never got hotter or colder and neither would smell exist if objects (or bodies!) never released smelly molecules. And time would not exist is nothing moved since time measures movement. Without movement, both practically and philosophically there would not even be a concept of time.

Lee Smolin's book is very clearly written and can be understood by the laywoman. (That's interesting – a lose-lose situation: 'layman' is a sexist word but 'laywoman' has sexist implications, "even a woman can understand the book.") I've read the long introduction and three chapters and I'm hooked. Smolin's career has been at the heart of modern physics and cosmology. In Time Reborn:..., he carefully presents a new paradigm that, if accepted, will do much to sort out the current controversies around the Big Bang, Dark Matter, String Theory and more. But the main reason I like this book is that it is the first popular science book I have read that agrees with me on the nature of time.
