At the heart of our galaxy lies a monster so deadly, not even light can escape its grasp. Its secrets lie waiting to be discovered. It’s time to explore our universe’s most mysterious inhabitants Also, as a reader who is not using these texts for any academic purposes, I think Cox’s writing is so much easier to ‘digest’ (and much more enjoyable in general) than Hawking’s (only comparing this to a few of Hawking’s books that I’ve previously read). I think it might be important to clarify that – I’m not comparing them based on ‘who’s the better (astro)physicist’ or whose ‘work’ was more ‘important’; but only of whose writing/books I had found more ‘enjoyable’. Hope that helps? Stephen Hawking uses an analogy in his 1974 paper to describe what's happening. You can picture the vacuum of space. If you could imagine zooming in and slowing time down with some great microscope, you could picture the vacuum of space as not being empty, as being filled with particles fizzing in and out of existence all the time. This is definitely a hard read. I had to read some chapters again and again to understand ( not fully though). So if you are going to read this book, and understand it thoroughly, you should spend some time on it. Alternately admiring and critical, unvarnished, and a closely detailed account of a troubled innovator.

I suppose owning a “Schrödinger’s cat: Wanted dead and alive” t-shirt didn’t actually qualify me to understand this book (although it certainly increased my nerd cred).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. He has worked on the Large Hadron Collider at CERN, Geneva, the HERA accelerator at DESY, Hamburg and the Tevatron accelerator at Fermilab, Chicago. Cox has written and presented numerous TV series for the BBC, including Wonders of the Solar System, Wonders of the Universe, Wonders of Life, Human Universe, Forces of Nature, The Planets and The Universe. He is also the co-presenter of The Infinite Monkey Cage radio series and podcast. Cox has written numerous bestselling science titles with Jeff Forshaw. For many years, he has lectured the introductory Relativity and Quantum Mechanics course at the University of Manchester, with Jeff Forshaw. 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. But this book proved me wrong from the very first spacetime Penrose diagram that slowly sent my protesting brain over the event horizon and to the singularity while being simultaneously vaporized and spaghettified. A warts-and-all portrait of the famed techno-entrepreneur—and the warts are nearly beyond counting. In his new book, physicist and science communicator Brian Cox explores how the new physics might help us reconcile the fundamental clash of principals stemming from our understanding of gravity at a cosmological scale and the physics of the minutia that underlies it, quantum theory. The first sign I was wrong is when I noticed a myriad of Penrose diagrams throughout the book - that is not something I’ve see in popular science books before. Sometimes you will get spacetime diagrams and usually very simple ones at that. As someone who studied physics 20 years ago as an undergraduate (and took a subject on relativity) I can honestly say I’d never seen a Penrose diagram before and I found them a really useful learning tool in the book. As I said, I’ve read a lot of books on this topic and adjacent ones (Thorne, Greene, Smolin, Carrol, etc) and I was genuinely glued to this one.

This is the ultimate vindication of research for research’s sake: two of the biggest problems in science and technology have turned out to be intimately related. The challenge of building a quantum computer is very similar to the challenge of writing down the correct theory of quantum gravity. This is one reason why it is vital that we continue to support the most esoteric scientific endeavours. Nobody could have predicted such a link. My reason for being sceptical is that I assumed this book would be a fairly watered-down affair with the usual dose of hand-wavy analogies that end up obscuring or misconstruing most of the real physics. Well, I was very wrong!At the heart of our galaxy lies a monster so deadly, not even light can escape its grasp. Its secrets lie waiting to be discovered. It's time to explore our universe's most mysterious inhabitants 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. There’s an old saying I think by Stephen Hawking that every equation you include in a popular level science book will half the effective book sales. Well, Cox and Forshaw deserve credit for taking a brave plunge (and by my estimate forgoing 99.999999% of their book sales based on Hawking’s formula) because one of the highlights of this book is the scattering of equations that are accompanied by careful explanation and insight.
