Publisher's Summary

You are reading the word now right now. But what does that mean? What makes the ephemeral moment now so special? Its enigmatic character has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond. Einstein showed that the flow of time is affected by both velocity and gravity, yet he despaired at his failure to explain the meaning of now. Equally puzzling: Why does time flow? Some physicists have given up trying to understand and call the flow of time an illusion, but eminent experimentalist physicist Richard A. Muller protests. He says physics should explain reality, not deny it.
In Now, Muller does more than poke holes in past ideas; he crafts his own revolutionary theory, one that makes testable predictions. He begins by laying out - with the refreshing clarity that made Physics for Future Presidents so successful - a firm and remarkably clear explanation of the physics building blocks of his theory: relativity, entropy, entanglement, antimatter, and the big bang. With the stage thus set, he reveals a startling way forward.
Muller points out that the standard big bang theory explains the ongoing expansion of the universe as the continuous creation of new space. He argues that time is also expanding and that the leading edge of the new time is what we experience as now. This thought-provoking vision has remarkable implications for some of our biggest questions, not only in physics but also in philosophy, including the ongoing debate about the reality of free will. Moreover, his theory is testable. Muller's monumental work will spark major debate about the most fundamental assumptions of our universe and may crack one of physics' longest-standing enigmas.

Not worth the time

This is a feeble attempt to use physics to conclude "a soul" exists.

The author puts down statements which cannot be tested throughout the first 20 something chapters ... then concludes with a statement which cannot be tested.

The book was well read and the book does address some of the interesting aspects of quantum physics and time ... but the author goes off the rails at the end.

There are plenty of other books on quantum physics and time ... I would NOT recommend this one.

Bewildering, mind blowing, ultimately enlightening

I'm an artist and writer, very right-brained, sadly inept in mathematics and the sciences. Yet I have always been fascinated by Physics. Physics has remained a bewildering foreign language to me. Over the years, I thought if I listened to enough words spoken in the language Physics, I would suddenly understand it. Until this book, my hope has been unfulfilled. However, about half way through this book, my brain experienced an awakening to the notion of symmetry. I can't explain it, but from that moment forward, I understood, haltingly it is true, how and why Physics reveals and predicts the universe and life. I am going to listen to this book from the beginning again and again.
