About this deal

An amazingly in depth insight into what the greatest minds are currently uncovering about some of the most fantastical aspects of our reality.

I recently attended one of Brian Cox's Horizons Live lectures in Manchester (which I reviewed here), where Cox proved to be engaging and able to explain difficult concepts clearly to a general audience. 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!

There are some bits that I have to ‘look up’ to understand better; and a few bits that I was like alright – I will highlight this now, but I’ll come back to it later. The authors are clearly very excited about black holes and did their best to be accessible, and it’s not their fault that when it comes to information of Mona Lisa level my brain gets stuck in an equivalent of a clumsy sidewalk chalk drawing by an overexcited toddler. The complexity of the topics discussed meant even Cox and Foreshaw were struggling to simplify the content to an universally understandable level. It's a complex but amazing book - the authors walked me through very many things I have previously not understood at all (despite intensive reading).A black hole in Einstein's theory is just a distortion in the fabric of space-time where even light itself cannot escape.

In this illustration, a supermassive black hole pulls a stream of gas off a star that passes too close. So if you are going to read this book, and understand it thoroughly, you should spend some time on it. You could almost imagine this kind of hot atmosphere of the black hole, which somehow contains the information and re-radiates it out into the universe again.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.
