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.

Interesting but surprising opinion

Overall the book is interesting and well written. A few notes though: I think his religious beliefs might distort his way of thinking or at least, at some moment, I felt the author is making an effort to reconciliate faith and reason. I don't agree with him regarding his opinion on free will and the existence of a soul beyond physical body, beyond consciousness. Those have no base other than belief. If it can't be disproved it does not mean it exists. All in all it's worth reading.

Worth the listen

I learned a lot and gained some perspective. I have read many physics books but this one has some better first principals explanations.

Also, nice job calling out physics on its shortcomings.

I could do without the free will and soul stuff.

Good start but bad end

Wery good in the first parts, but gets pseudo religious in the end. Thats a turn off, and the reasoning behind the theory of Now is just an opinion.
