About this deal

Not that I want to throw your book into a black hole, but what would happen to it and the information that it contains if I tossed it in? 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. Perhaps it is inevitable that human beings will encounter enchantment when they commit to exploring the sublime. However, through the tangled web of math and concept, the things that I was able to glimpse were quite mind boggling. In short, I didn't get swathes of it but apparently, I am a sucker for the particular kind of inspiration that uniquely comes from being made to feel dumb by a 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. For any-and-all of us who interested in the leading edge of our understanding of the universe -there is no one better to explain it all than Brian Cox (now recently joined by Jeff Forshaw).

They have blazed a clear trail into forbidding territory, from the mathematical structure of space-time all the way to atom bombs, astrophysics and the origin of mass. They help us to know which pages are the most and least popular and see how visitors move around the site.

At the heart of the Milky Way lies a supermassive black hole 4 million times more massive than our Sun. 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. Os mistérios do universo - a maravilha do espaço infinito, inexplorado - e do espaço conhecido, que não deixa de fascinar quem se dedica a estudá-lo.A black hole in Einstein's theory is just a distortion in the fabric of space-time where even light itself cannot escape. We have a picture where the interior of the black hole becomes — in some sense — the same place as the exterior. 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. In this artist's rendering, a star makes its closest approach to the supermassive black hole at the center of the Milky Way.
