I still remember the moment I comprehended Gödel's incompleteness theorem as well. It was one of the most memorable moments I had at University, both wonderfully meta and terrifyingly nihilistic. Watching Sir Penrose on Joe Rogan's podcast left me wondering if his and Dr. Carroll's relationship would be adversarial. Corrigibly, Dr. Carroll once again renews my hope in humanity. Mindscape quickly became my favorite podcast. "Hello everyone" brightens my day every time.

Axioms, as exemplified in Russell's _Mathematica_ are abstracts which may work wonderfully well _within_ math and allied logic; but have problems outside that milieu. You mention Joe Rogan - who I never really felt to be very funny, is an 'all-American' muscular kind of guy - but too many muscles instead of brain matter :0)

More the moment than the theorem. The theorem is not actually nihilistic, but first interpretation brings that feeling, that even a buttoned up theory has inconsistencies baked in. It makes me doubt that a theory of everything is achievable. It's not a proof that it is not, but it adds to the doubt. I'd like to note that that feeling is subject to woo exploitation, similar to many quantum physics concepts being exploited. It is important to not let emotion cloud the rigorous structure of math. However, emotion is sometimes the spark of insight.

Fascinating! Thanks, professors!

The best episode so far!!!!

Maybe I’m willing to get his book on cyclical cosmology now. - I’m not sure I understood how he gets to the “ring” seeds in the next aeon’s CMB: first he mentions mergers of supermassive BHs (implying that the messenger in the transition would be gravitational waves) that he somehow thinks as reappearing as DM in the new aeon, and for the smaller structure he mentions Hawking-Radiation as the origin. - I mean I do get the general idea from particle physics that energy can transform into all kind of new particles / waves in quantum fields can transform into other waves in other quantum fields, but I was under the impression, that there are clear pathways for everything, and that the probabilities for those pathways in the standard model are exceptionally well known (allowing the Higgs to be found by applying enough statistics etc.). - What I’m trying to say: fitting one gap in our understanding with another gap is not very convincing to me, especially in the case of consciousness, while the case for cyclical cosmology sounds less far fetched, it again sounds like using a gap / placeholder in our knowledge for another bold claim. - I am empathetic with his teleological impulses: when the end of our aeon has similarities with the beginning, you want to find a way to tie it together and make it cyclical. Or when he concludes that our mind would not work on a computational basis by combining the idea of Gödel’s paradox with the idea of solutions that are uncomputable on a Turing-Machine, and plugs it with the unsolved problem of the collapse of the wave function (- for which itself he makes an interesting proposal,) and tries to give it a biological location to happen (micro tubulars). - But the fact that the creative associative thought process in his mind decides to jump to the seemingly next free unoccupied niche in the topology of idea-space does not make it necessarily a “true” idea / the next best description of the world. Still it is an appropriate thing to do for a scientist who still wants to connect the dots in creative new ways, and can afford to do so. - When you think about it: after all this time and thinking and conversations he not only sees more dots than most people, he also knows how the lines of that big picture have been drawn in the past by large amounts of important people, and yet he is still able to see it differently - that seems like a rare gift. Granting accomplished scientists more artistic license still seems quite affordable to me in the grand scheme of things.

Penrose will be 88 in August. If you look at his family tree, his grandfather, father, uncle, brother and children are all singular. Between Dennis Sciama and Penrose, their graduate students at Oxford and student descendants dominate many areas. Sciama was the dissertation adviser to forty Ph.D. students including, Hawking, Martin Reese and David Deutsch. Penrose's thirty students and 164 descendants are likewise impressive. It's hard to calculate both Sciama and Penrose's long term impact ; one or both should be a Marvel character.

Hey, so one question comes to mind. As a black hole evaporates, I see a point at which the density no longer keeps the mass below the Schwartzchild radius. Is that a reasonable line of logic? And if that happens, does what was once the black hole then begin a period of further expansion, perhaps even rapid? I'm wondering at what happens to the weirdness of the event horizon once the mass is no longer capable of sustaining it, if that ever happens. Or would the mass simply whimper into a neutron star? And if so... I better stop. I got questions :-)

You're not alone.

I have a question about the "The end of the universe - everything's massless - conformal invariance - looks just like the Big Bang - so maybe it becomes a new Big Bang" hypothesis. How does the second law of thermodynamics work in this model? Entropy keeps increasing, then suddenly is vastly decreased (breaking the second law?) when all particles are massless, so things can start over again? How does that decrease come about? And a second question: the hypothesis assumes that all massive particles either eventually decay into massless ones, or they eventually get swallowed by a black hole. But there will be lots of massive particles floating around; will they be swallowed up much faster than the black holes evaporate? If not, then even if there's only a single stable massive particle left in the universe after all the black holes have evaporated, the model fails, right? Also: black hole radiation can also be massive (particle anti-particle pairs). So now these new particles have to meet their antiparticle, or decay into radiation, or get swallowed by a black hole again, in order for there to finally be no massive particles in the universe. This, in a universe that is still expanding exponentially fast, separating particles from each other. Why is this not a problem for the model?

@pauldavidhaynes8243

4 жыл бұрын

I'll try point you in the right direction, Q1. Total entropy never decreases, but there's a change from high gravitational entropy to low, on the other hand low temperature/kinetic energy to high. Total combined same or never decreases. Q2. You have to broaden your mind to the time scales involved here 10^100000 years everything will be pulled together into one object through gravity. Hawking radiation is massless, it's very low energy light, long wave length..... Finally as black holes evaporate and become smaller they become hotter and evaporate faster exponentially untill they hit a critical point which would be the new big bang - cycle. Im a non physicist but read alot and in a brief answer, I think that's right.

His "infinite cyclic spacetime" model is aesthetically pleasing. But what if (I thought) we take this idea of sticking infinite future boundaries onto big bangs - which results in a spacetime tube or "block universe" of infinite length - and bend it so that we get a torus? With even one more extra dimension, we could tie a frickin' knot in it! Hang on. Is this recursive (fractal?) string theory?

Consider Terrence Deacon, David Pierce or Giulio Tononi for a conversation over consciousness, self and moral implications.

Here is something I have wondered about lately. Where does the "Space" go that was a part of the Atoms of Matter that falls into a blackhole. If The Singularity is a theoretical point of Infinite density the there has to be a lot of Space that moved somewhere else. Could it be connected to the observed rise in the amount of DE. If Spacetime itself is "something" and that something is a conglomerate of Space and Time then when matter is compressed by the Gravity of a blackhole or even something like a Neutron Star the the Space portion of the Matter has to either move or be destroyed.

As a 'layman artist' (working with object design in 3D CAD software - 3D 'Euclidean space' - for 10+ yrs) ... To me 'intuitively' - Penrose's images or explanations of the 'space-time' geometry seems 'infinitely' more plausible (pardon the pun) than what comes from the somewhat 'mysterious' interpretations of QM. The 'superposition' statement of QM - that a thing can be in two "places" at once - is inherently 'geometrical' it seems to me. To talk of two "places" you must be able to distinguish them apart. They must be separated by 'space'. This is by definition what "geometry" is all about. So if QM is simply 'ignoring' the space-time "geometry" it seems paradoxical to me; like ignoring an inherent feature or aspect of the thing 'probed'. Or deliberately blindfolding yourself to some extent - which seems much like the 'Bohr approach'. - A little thought experiment: If everything in the Universe was in a state of "superposition" - how would you define "space"? If no 'position' can be distinguished from any other position - there is no notion of "space"... Or at least it could not be 'defined' or 'measured'. As soon as you introduce the notion of "two places" - you introduce the need for "geometry" - and thus the need to account for the preceding gravitational field or the history/evolution of the 'space-time-geometry'?... At the 'moment' (or 'interval of time' rather) of your "measurement"? Even if you imagine 'measuring' the very first pair of particles that emerged from the Big Bang... This would apply? Imagine 'the first' particle... a single one. How would a 'measurement' even take place? What is the particle 'relative' to? If there is only one 'measurable' thing in the Universe? Comparing the 'designing' of cosmological theory, to a 'creative' design-process. This would be equal to saying: Its OK to focus on the tiniest of details - and just forget about the overall design or 'shape' of things. Something that any artist will tell you - tends to yield bad or 'ugly' overall results. Yielding perhaps a number of sublime details... but not 'coherent' or 'beautiful' as a whole. In the creative design-process it is essential to keep 'zooming in and out'. You may zoom in on a detail and change it or 'refine' it... but always 'zoom' back out and review the whole 'shape' when you do so. Perhaps its time for QM to 'zoom out'? ... if only for a while... you can always zoom back in. :)
