Chapter 7 - The Debate {Hawking and Penrose}
Einstein said that the most incomprehensible thing about the universe is that it is comprehensible. But was he right? Can the quantum theory of fields and Einstein's general theory of relativity, the two most accurate and successful theories in all of physics, be united in a single quantum theory of gravity? Can quantum and cosmos ever be combined? On this issue, two of the world's most famous physicists--Stephen Hawking ("A Brief History of Time") and Roger Penrose ("The Emperor's New Mind" and "Shadows of the Mind")--disagree. Here they explain their positions in a work based on six lectures with a final debate, all originally presented at the Isaac Newton Institute for Mathematical Sciences at the University of Cambridge.
How could quantum gravity, a theory that could explain the earlier moments of the big bang and the physics of the enigmatic objects known as black holes, be constructed? Why does our patch of the universe look just as Einstein predicted, with no hint of quantum effects in sight? What strange quantum processes can cause black holes to evaporate, and what happens to all the information that they swallow? Why does time go forward, not backward?
In this book, the two opponents touch on all these questions. Penrose, like Einstein, refuses to believe that quantum mechanics is a final theory. Hawking thinks otherwise, and argues that general relativity simply cannot account for how the universe began. Only a quantum theory of gravity, coupled with the no-boundary hypothesis, can ever hope to explain adequately what little we can observe about our universe. Penrose, playing the realist to Hawking's positivist, thinks that the universe is unbounded and will expand forever. The universe can be understood, he argues, in terms of the geometry of light cones, the compression and distortion of spacetime, and by the use of twistor theory. With the final debate, the reader will come to realize how much Hawking and Penrose diverge in their opinions of the ultimate quest to combine quantum mechanics and relativity, and how differently they have tried to comprehend the incomprehensible.

I could never understand what's in there!Some of this information is dated, which is to be expected reading it so long after it was written. I could follow most of the math, but was disappointed by the lack of variable definition. Penrose's writing was much more clear than Hawkings and I believe I'll search out some of his writing on the topic the next time I approach this subject.
Lots of diagrams. Has a lot of loaded philosophical statements that were useful when writing a thesis. Helps to explain singularity, cosmic censorship, etc.
Not good. Notes from a Cambridge series of lectures. Colloquium level for PhDs in Quantum Gravity and Cosmology. Terms are not explained. Equations are not explained. Familiarity with 4 spheres, deSitter spacetime, Euclideanization of spacetime is assumed.
"Time is the fire in which we burn." Delmore Schwartz"...time is a companion who goes with us on the journey and reminds us to cherish every moment, because it will never come again." Jean-Luc PicardI found the information in this set of 3 lectures to be somewhat interesting but because I am not a student (or practitioner) of science I found it to be a bit too specific to the field of physics/quantum mechanics/advanced maths/etc. for my general interest.That said, one big problem I have with
If you're into stuff like this, you can read the full review.Shut the Fuck Up and Calculate (Or Not): "The Nature of Space and Time" by Stephen Hawking and Roger Penrose"I have emphasized what I consider the two most remarkable features that I have learned in my research on space and time: (1) that gravity curls up space-time so that it has a beginning and an end; (2) that there is a deep connection between gravity and thermodynamics that arises because gravity itself determines the topology of
This is collection of essays is an argument between Hawking and Penrose about the origin and ultimate fate of the universe, plus some entropy notions about black holes. I will say this: Hawking throws equations out there like you flat out know what he's talking about. His disclaimer is that he assumes you know some math and quantum mechanics. The QM arguments were easy enough, and while I've seen some topology before, I wasn't hugely familiar with GR, so his essays were sometimes hard to follow.
