With stunning illustrations and insightful analogies, the book takes readers on a journey through the universe, exploring the formation and behavior of black holes. If you do not allow these cookies we will not know when you have visited our site, and will not be able to monitor its performance. 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. The last few chapters explore the possible ideas of connecting quantum mechanics with gravity, as well as a theory that the world might be a hologram. 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.

So that means that the one on the inside is not coming out, but the upshot is the one on the outside that would have gone back and re-merged with its partner, essentially giving its energy back to the vacuum, can be made real and can escape into space.Minkowski spacetime diagrams are however touched upon very briefly, and meeting them again in the later chapters I was a bit confused.

They were explored in depth (haha), and some concepts were really challenging (like how space and time change places inside the black hole), but the youtube videos helped making some sense of it.

Chandrasekhar's work laid the groundwork for understanding the conditions under which massive stars can evolve into black holes, contributing significantly to the theoretical framework of stellar astrophysics and the formation of black holes.

I'm embarrassed to tell you how many books I've bought that said they were going to explain quantum mechanics.

The complexity of the topics discussed meant even Cox and Foreshaw were struggling to simplify the content to an universally understandable level. 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. The more the authors enlightened me about Black Holes, the denser my brain became until I eventually passed through the Event Horizon (my ability to read further) which resulted in a Singularity.

One of them is the description of Einstein and then there's another description, which just looks like some kind of quantum theory, some kind of building blocks of the universe that are entangled together.Cox has written and presented numerous TV series for the BBC, including the Wonders Trilogy, Forces of Nature, The Planets and The Universe. Information processing – the churning of bits from input to output – is not a construction of computer science, it is a feature of our Universe. 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! But for a while, I got hung up on proposed visual observations in the book and therefore somewhere had misunderstood.
