How well-founded are our ‘commonsense’ ideas about time? Does time ‘really’ flow inexorably forward? Or is it ‘all in the mind’?

Starting out from the everyday experience of time, the rhythms of day and night and the seasons, and the International Date Line, John Gribbin goes on to the deeper mysteries of relativity theory, quantum mechanics, the implications of black holes

I've read and enjoyed quite a few of Gribbin's books, but I'd have to say that this particular one did not impress me much. The first part of the book was interesting. However, the author went a bit off the beaten path in the latter parts; discussing hypnotic life regression, reincarnation, Eastern philosophies, I Ching, etc. Just a bit much for my tastes in science reading.

I understand he was speculating with regards to the topic of the book; looking at all the possibilities, including those j

If you read John Gribbin's more recent works, this book—owing to its age—has a feel of a younger, more naive, and aspiring author. The book definitely touches a wider area than I expected from its title. Instead of brief account of General and Special relativities, with subsequent mathematical peculiarities, Gribbin ventures into the areas of philosophical, psychological and mythical views of time travel (nonetheless, he manages to present the mathematical peculiarities as well). Whilst some of ...more

The two first parts of the book were very interesting and offered insight on various topics about the nature of time, but the third part went too much into metaphysics which I didn't really enjoy. John Gribbin has a way of explaining scientific concepts in very approachable ways though.

The last section on unconsciousness is what separates this work from the usual physical time travel books

I loved this book - it really opened up my mind with regards to time-travel, parallel universes, etc.

John Gribbin is (was?) a great science writer, and his clear narrative and excellent supporting diagrams are excellent at getting across some fairly complex concepts easily.

Just flicking through it 35 years later, I can see that much of what the author has explained remains current thinking. It goes to show just how hard it is to prove in practice much of what is theorised at this level.

The review by Zoffix Znet dated Nov 10, 2013 sums up my thoughts very well. I'd just add that it's a fast-paced, easy read, no math required, it covers a broad range of ideas using a very comfortable writing style. The author is quite smart but doesn't waste time making sure you know that, I'll definitely read more of Gribbin's work.

General relativity theory with a dash of mysticism. Laughable at times.
