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.

A book with good beginning that fizzles out in end

This is one of those books which could have been exceptionally good but fails to make it. It started off well and I developed high hopes only to find that as the book progressed it became philosophical ramblings of the author instead of a science book for lay people.

For example, in the latter part of the book the author starts discussing about soul and makes a point that he feels that he certainly has a soul though he is not sure about other animals. I have just one question for the author - if we have something like soul which other animals don't have , at what point during evolution did we develop it? Every cell in our body is a living thing , so does it mean that your soul is divided among trillions of cells?

Despite its flaws the book does shine in bits and pieces. Some topics have been explained well.
