Bringing the material up to date, Black Holes, Wormholes and Time Machines, Second Edition captures the new ideas and discoveries made in physics womholes the publication of the best-selling first edition. While retaining the popular format and style of its predecessor, this edition explores the latest developments in high-energy astroparticle physics machinrs Big Bang cosmology. The book continues to make the ideas and theories of modern physics easily understood by anyone, from researchers to students to general science enthusiasts.

Taking you on a journey through space and time, author Jim Al-Khalili covers some of the most fascinating topics in physics today, including: Black holes Space warps The Big Bang Time travel Wormholes Parallel universes Professor Al-Khalili explains often complex scientific concepts in simple, nontechnical terms and imparts an appreciation of the cosmos, helping you see how time traveling may not be so far-fetched after all.

It is full of interesting concepts and well worth the cost of money and time to delve into. One concept that the book covered well was the fact that time slows down as an individual travels faster. Although other books have covered this concept, the examples that this book used made the concept real and much more understandable.

Personally, I especially liked the chapters on wormholes. Although other books that I have read recently have covered these concepts, this one, using the recent book Contact starring Jodie Foster and made in gave some reality to how this would work. I highly recommend this book for any interested in astronomy and the universe. This book is very well written with amazing examples to aid the reader with such complex topics as general relativity and quantum mechanics which can be quite confusing at first glance.

I am sure to read this again as to gain a further grasp on the subjects in this addicting book that I had a hard time putting down. It is fascinating thoughtful, thought provoking, and pleasing to read at the same time, with many ties to popular culture and up to date physics.


I must also admit that this book made me look up to the night sky several times after I read it and in my opinion is a great read jik the physicist and non physicist alike! The author has a knack for explaining complex ideas that involve the vastness of the universe and the tiniest theories of Quantum mechanics with clarity and insight. This is a good one to add to the library which I will for sure pull out of mine several times for future reference. One person found this helpful. Well written, clear, easy to understand.

That sums it up.

Black Holes, Wormholes and Time Machines – CRC Press Book

We checked this book out at the local library I lost count and eventually ordered it for my teen science junkie — last Christmas. The material is not really dated. The concepts apply today just as they did when the book was penned.

If you want a good introduction to black holes, wormholes — and the differences between the two, with pictures, well then what are you waiting machiens Astrophysics for those of us who never took a physics class in school. You need not be a genius to understand the majority of this book. It’s easy to read and explains complex topics in a relatively simple manner. This book is similar to Kip Thorne’s book: I place both books about equally in their readability to the common person, and amount of interesting information about our universe.

This does a great job of explaining different theories about the universe and why some are more likely than others, as well as faults with various theories. Very interesting, but certainly not light reading!

I am a proud owner of the 1st edition of this book and purchased this one because it is the more recently released 2nd edition. It was my favorite book on the topic to date so wromholes the 2nd edition was a no-brainer. So what do I think of this book? Al-Khalili is no doubt a master at taking esoteric physics concepts and breaking them down into terms for anyone who has a genuine interest in the topics covered to understand.

Another commenter here said he read the whole book in two sittings. Congratulations are in order for him. I, on the other hand, had to slowly comb through this book digesting the knowledge a little at time before I can move onto the next section. I read about twenty pages at a time for about a sl. I would often reread areas to make sure I knew exactly what was going on.

Not because it was difficult to understand what he was saying but because it was truly machlnes for me to completely digest. It’s more than just fascinating and lhalili deserves to be chewed swallowed. Al-Khalili brilliantly connects chapter to chapter helping you understand dimensions, gravity, the universe so much more complex – even though he tjme a wonderful job explaining – than I could even have imaginedblack holes, white holes, Einstein and his theory of relativity it’s a really big deal and he doesn’t downplay how big of a deal it isparadoxes, and finally a move into where physics is today and what our leading – most abstract?

All of it beautifully rendered with illustrations and real-world easy to understand examples. Having read the first edition and now the second edition and although I’d recommend this book strongly to anyone nlack an interest in these topics that isn’t perusing – or has – a degree in physics, I blac a couple of gripes I’d like to la some attention to.


Maybe some of these are my own lack wormhols understanding and inability to grasp what the author is saying, but, nonetheless, they left me confused and once or twice a little disappointed. Al-Khalili holess wrote the first edition of this book years ago, and during that wl Pluto was still a planet. Given, this is petty, but if you’re updating older material and releasing it as a new and improved edition, shouldn’t you look into all the details?

It is my understanding that Pluto, although now considered a dwarf planet, is not truly our ninth planet anymore.

In fact, it is one of many dwarf planets beyond Neptune. Next there is a line from his first edition repeated in this edition explaining that the cosmological constant was the biggest mistake of Einstein’s scientific career.

While at the time that may have been believed to be the case this book goes on to explain that the cosmological constant is back in play and is actively being used in modern equations.

Black Holes, Wormholes and Time Machines

So was it a mistake or not? A simple word change would get rid of some of the confusion this can create. He then deals with the shapes of the universe from open to closed and finally flat. I understood this ak because of his examples of what open and closed were, but I feel he kind of jumbled it a little in the end when explaining the difference because these and a flat universe.

It sounds like it becomes static since open means eternal expansion and closed means a recollapse. However, in the next sentence he says “Instead, the density of matter would be such that its gravity will steadily slow the expansion rate down, but never quite stop it.

This corresponds to a flat universe, neither open nor closed. Gravity cannot stop the expansion in an open universe, fine.

But gravity also cannot stop the expansion in a flat universe? It just keeps expanding, just maybe slower? What then is a flat universe? Is it that gravity just slows it amd Wouldn’t that happen anyway within an open universe? A little more explanation here would do wonders because it just doesn’t appear clear enough to be easily understood. Now he moves onto the paradox of the twins.

It is beautifully explained and easy to understand. However, he injects his beliefs as to why there is no paradox here. Without going into detailed explanation, his idea defeats the paradox only if the universe is as he believes it to be; open.

He explains shapes of the universe wonderfully earlier wormhole in the book, but doesn’t reference here that the paradox will still exist if the universe is positively curved and closed. He explains throughout the book his ideas and other’s ideas and where they disagree, but fails to do so here, which is a little disappointing.
