About this deal

Nor am I particularly skilled at focussing on multiple things, fond of starting over, or withholding anything of value from the theoretical physicists that they haven't already got covered. billion light years away, the LIGO instruments have recently detected something that could be the closest a black hole gets to death.

If Hawking was right, black holes would render the Universe fundamentally unpredictable and the foundations of physics would crumble. Now, I’m not sure how this works (no shit), but from what I understood, it’s from the point of view of the external observer that information rests on the surface, but maximally-scattered as if the infalling person was vaporized. Rather we might conclude that the language of computing is well suited to describing the algorithmic unfolding of the cosmos. Having read some other reviews, I’ll read some more of their books to see if the message is a bit clearer, or I just don’t get it.Black holes are places in space and time where the laws of gravity, quantum physics and thermodynamics collide. 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! 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. This results in a paradox of essentially creating two copies of the same object / person: one spaghettified, one vaporized. But the things that I did understand were quite fascinating, although my brain slid off a few pages that looked like this and gave me a flashback to a college physics textbook that may have caused a few nightmares a couple of decades ago.

However, the Cambridge-Manchester commute is killer, and I have somewhat spotty Physics marks from prior attempts. 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.This is one reason why it is vital that we continue to support the most esoteric scientific endeavours. The wonderful thing about the ever-increasing number of black holes we have discovered dotted across the Universe is that each one is an experiment conducted by nature that we cannot explain.
