Description

I have read – and mostly understood – a fair chunk of popular science in my time, and found this book severely wanting when it came to popular science's most important task: bringing the reader along. I especially appreciated the clear explanations of Penrose diagrams and their use to explain different types of black holes. But even though this it's hard to read, I think we can see through these theories from a mathematical point of view. Theoretical physicist Stephen Hawking's 1974 theory about black holes having a temperature kickstarted what has become a quantum revolution in astrophysics. As a science book, I'm sure this must be a remarkable and accurate piece, but as a popular science book, it must be considered something of a failure.

A black hole in Einstein's theory is just a distortion in the fabric of space-time where even light itself cannot escape. A glowing stream of material from a star is disrupted as it was being devoured by a supermassive black hole surrounded by a ring of dust and illuminated by high-energy radiation. This is a beautifully add masterfully written synopsis of the universe as a whole tying together, very complicated theories and ideologies into something readable, and more importantly, understandable.Anyway, the two particles would be entangled, and one of them escapes, while the other one remains inside the hole. This results in a paradox of essentially creating two copies of the same object / person: one spaghettified, one vaporized.

If a traveller matches the speed and direction of that visual information moving through space, the traveller will observe the object to be frozen still for as long as the traveller maintains that heading and speed. Imagine that a pair of these particles, which would have come into existence and disappeared again, they can be configured such that one's on the inside of the horizon and one is on the outside of the horizon.

But it is intriguing, to learn purely theoretical black holes derived only from Einstein's General Relativity. I like Brian Cox's TV shows and i am going to see him Live next year, this book is excellent but heavy going, i think it is impossible to explain these things in simple terms, so it will take me awhile to navigate this book, one section at a time! Minkowski spacetime diagrams are however touched upon very briefly, and meeting them again in the later chapters I was a bit confused. My experience this morning: I finished reading a pop science book about black holes that I tried very hard with but largely didn't understand.

It's a fair point, but the book itself doesn't do enough to bring those esoteric ideas into the minds of the mainstream reader, and the impact of this profound discussion is consequently diminished. Highly recommended for educated readers who can kepe up with a little hard science that hasn't been overly diluted for general consumption. Anyway, now we come to another “real” (in a sense that it was observed) property of black holes - Hawking radiation. In this artist's rendering, a star makes its closest approach to the supermassive black hole at the center of the Milky Way. I can't hold my excitement when the author introduces Quantum Computing with its relationship with the Holographic Principle to simulate our spacetime reality.

So if I finish the book and I still don't understand the universe, they're going to tell me it's my fault. The role of information science in describing black holes may be pointing us towards a novel description of Nature, but this does not imply we were programmed. What I’m trying to say is that I don’t think that this book is only for the space-ey academics; anyone can enjoy it too. If the Rotations per Minute (RPM) of a spinning wheel matches the frames per second (FPS) of a video camera then the wheel on film is observed to slow to a stop.He is best known to the public as a science broadcaster and presenter of the highly popular BBC2 series Wonders of the Solar System. I can think of no one, Stephen Hawking included, who more perfectly combines authority, knowledge, passion, clarity, and powers of elucidation than Brian Cox. There’s time dilation, as well as the twin paradox – I liked the idea that you can “gain time” compared with stationary observers while accelerating, but this also can cut you off from some regions of spacetime (now some ideas in Death's End by Liu Cixin make more sense! It’s always tempting to bask in the self-congratulatory delusion that if I just really concentrate on something hard enough I’d be able to understand it. The equations of general relativity describe how matter and energy influence the curvature of spacetime, and they predict the formation of singularities, regions where gravity becomes infinitely strong, as in the center of black holes.

And, I didn't expect that I would learn the Penrose diagram to understand the infinities of spacetime. We have a picture where the interior of the black hole becomes — in some sense — the same place as the exterior. If you don't see a follow up to this review it means I've found the wormhole to another universe or travelled to another time or dimension. For such a genius to be able to explain things in everyday terms but still be “grounded” and throw in everything from Monty Python, through Hitchhikers Guide to Manchester drizzle (and you need to have lived in Manchester to understand that is not bad), this book is a must have, as the sheer enormity of the concepts and expanse of space and all that go with Black Holes.Obviously I know Cox is a great science communicator and his previous books with Forshaw have been really well received. If anything, I found the writing very engaging, and I think it could easily appeal to anyone who is willing to put in a little extra effort. Professor Brian Cox CBE FRS is Professor of Particle Physics at the University of Manchester and the Royal Society Professor for Public Engagement in Science. It's a great shame, because the cutting-edge ideas delivered, however imperfectly, in the book are fascinating and profound.
