About this deal

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 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. If the wheel rotates faster than the cameras FPS then the wheel on film is seen to Counter rotate, seeming to spin in the opposite direction. The topic is an intense and difficult one, even before you get to the cutting-edge stuff which the authors discuss in the final chapters.

When you say bits of information, I usually think of bits that are used in terms of computer science to describe a zero or a one that encodes information. An amazingly in depth insight into what the greatest minds are currently uncovering about some of the most fantastical aspects of our reality.Meanwhile a person crossing the black hole event horizon would feel nothing out of ordinary (except for being spaghettified), but the spacetime is stretched out so much that the outside observer would never see the infalling person cross the event horizon, so the information about them would rest on the surface? Generally Cox is really good at simplifying complex ideas but here, except for the odd paragraph or two, he failed. From the perspective of the book or the astronaut, you can fall across the horizon into the interior of the black hole.

The complexity of the topics discussed meant even Cox and Foreshaw were struggling to simplify the content to an universally understandable level. 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.All of this disregards entirely that I am already sort of tied up with a pseudo-career in a different scientific discipline and do not relish the thought of attending university again. Now, as a general rule, whenever someone produces a graph I reach for my revolver, but I imagine even those readers who are more inclined to jump through the various mathematical hurdles Cox and Forshaw erect will find them a bit excessive. With this book, we will explore the possibilities of the interior of a black hole, starting from Schwarzschild's eternal and non-spinning black hole, Kerr's eternal and spinning black hole, Hawking's non-eternal (radiating) black hole, until the duality of our reality: the Holographic Principle.
