I don't get all of these negative comments on this video. Guess it's just KZread, and people like to complain. I think it's a great, accessible lecture, in which Mr. Penrose tried to explain difficult concepts in clear language. Thanks for taking the time to upload it!

The best part is when he puts up an illustration and the camera refuses to switch to it in preference to showing him looking down at something we will never see and point all sorts of things out.

Absolutely fascinating. I've struggled for years to read and understand these concepts, and Penrose spouts them off like their his children's names. Wonderful presentation.

"The BIG Bang-Bit Bang was a supermassive white hole - inflation/expansion of energy-matter and information 13.8 billion years ago - spawned by a supermassive black hole at the heart of a galaxy in our 'parent universe'. This duality combines general relativity’s singularities of infinite density in a ‘Cosmic Egg’ birth of this and all universes within 'The Conglomerate': multiverse without random bubble universes and parallel worlds. Our Universe exists inside the Planck density of that SBH and shares the same boundary/event horizon. That SBH-SWH phase transition was a 'quantum tunneling umbilical wormhole' with energy-matter & info transformed/transferred, although scrambled & encoded. This fractal Universe is 1-in-2 trillion+ offspring each w/ similar inherited ‘DNA’/physical constants. This ‘simple’ cause- and-effect cycle/'circle of life' - birth-life-death-transformation-rebirth - explains both infinite space and eternity. Reproduction is the simplest plan of continued existence for everything from cells to universes." - part of Seal #1 of the 7seals.blogspot.com .

Brilliant lecture concepts, naïve photographer, a few tired old men. (I'm 70 myself so I probably would have been resting my eyes during the beginning material too). I'm delighted that professor Penrose's concepts are fleshed out versions of my own pitifully vague ideas that I've nurtured for 20 years. Glad to have found him. He's crystalized what I just mushed around in.

The important difference for me is that the weightlifter is engaged in a pursuit that benefits themselves. The professor and a big chunk of the rest of the world are engaged in pursuits that affect me. I don't know how to build my own PC out of raw materials, but I sure value the smart people in the chain that went into making it possible that I can benefit from all that research and work. So I'll always encourage scientific exploration, even if I can't directly see an immediate benefit.

Looking more and more likely that RP is right - 12 years on… beautiful presentation and excellent questions and moderation.

As the waves come from a distance radius compressing the wave amplitude (like dropping pebbles into a pond) 4pi R2 forms a potential infinity of future possibilities at every degree and angle of space and at every moment of time. This can be seen in a two slit experiment when someone turns on a light from a detector adding energy compressing the wave amplitude the shorter the expanding wave lengths the greater the energy. Time is inverse multiplying +/- dividing like frequency and wave length.

I totally agree. The two big questions; The origins of the universe and the nature of conciousness. In Penrose's model there maybe an explainable cohesion of the two. That's just a feeling. There are several brilliant scientific minds around today, Penrose is certainly one of the very best in that he's prepared to almost discard a previously established scientific idea if it's led to a standstill. Then he produces an alternative model which is definitely testable. I've no doubt that people will be looking for the smoking gun on this one, with a very good chance of finding it.

Absolutely brilliant! Dr Penrose never ceases to amaze. I can't help hearing a certain "ring of truth" in what he says here. As always, his logic is elegant and conceivable, the latter in particular being something that's difficult to say about notions like string theory as any kind of insight into cosmology. I think 100 years from now, people will continue to confirm his views, much as we do Einstein's today.

I thoroughly enjoyed the lecture and hope the hypothesis gets rigorous testing and research support from the community and supporters to see if Professor Penrose's theory is right.

I should add that acetate slides are far more flexible in use than PowerPoint - you have to be very expert as a PowerPoint manipulator to hop back and forth as the occasion demands DURING a talk and as one's thoughts arise even during a presentation such as this.

When Roger Penrose speaks of Black Holes having very low temperatures I imagine that's because Physical Space at -273 degrees is bearing down on it at the speed of light, it's hard to visualise there being any temperature above absolute zero. Can anybody tell me why is it that the theoretical "Information" which is squeezed out of the event horizon due to Hawking Radiation is not instantaneously swalloowed up again by the Black Hole? I just don't see how it could escape the unimaginably overwhelming force of the actual fabric of space which, to repeat would reach FTL velocity at the event horizon. I trust that there are plans to preserve Roger Penroses acetate drawings-they really are good- for posterity, they will be revered and marvelled over for as many cernturies as we have left. He is a remarkable man and is a great source of encouragement for me in my studies (albeit rudimentary) of Physics.

This is an invitation to see a theory on the nature of time! In this theory we have an emergent uncertain future continuously coming into existence relative to the spontaneous absorption and emission of photon energy. The future is unfolding with each photon electron coupling or dipole moment relative to the atoms of the periodic table and the wavelength of the electromagnetic spectrum. This is part of a universal process of energy exchange that forms the ever changing world of our everyday life.

So then there is a maximum size limit on a black hole? Could massive merging black holes reach this maximum entropy level? Would they explode like a hyper hyper nova after reaching this limit? Could that qualify as a big bang?

PLEASE make a post on the relation between DIV GRAD at finite density charge sources and the relation of this to gravitational curvature for finite density mass distributions.

Yeah!! "David Bohm sees the manifestation of all forms in the universe as the result of countless enfolding and unfolding between these two orders. Therefore, the explicate order corresponds to the physical world as we know it in day to day reality, the other deeper order is the implicate order, which is like a vast holographic movement. We see only the surface of the implicate order as it unfolds. Most neurological investigations show how action is indeed taken before becoming conscious of it."

Man I’d love to understand this guy!😁

What is the music at the beginning?

I've been trying to figure out what it is about this theory that bugs me. I think the issue is that the conformal mapping from end to next beginning has an effect of changing the metrics of the meter and/or second. While the mathematics of conformal mappings is very elegant, it basically says "metrics don't matter". In physics, though, the metrics DO matter. So, it seems like there's a bit of hand-waving going on about the transition from old to new. Granted, we haven't looked at the math, but the change in metric bugs me.

There once was a lady named Bright, Who traveled much faster than light, She started one day in a relative way, And returned on the previous night!

So if I understand the lecture correctly, if I get the gist that is, is Sir Roger saying that overhead transparencies came before the big bang? Or am I missing the (Power) point?

Photons does not have mass, but since it moves at the speed of light it has momentum.

I hope I'm wrong 19:35 , he says the log of the volume is the entropy.... the argument in the log should be the complexions number Wi, the number of possible configurations the systemcan possibly occupy, so is there any equivelence upon which he's stating this, sounds weird to me.

@horrorshowchai

9 жыл бұрын

Hmm? I don't see a problem with that. The volume isn't the 'number' of configurations of course, it's some metric on a continuous phase space. And it's not the total number of configurations, it's the volume of some subset. But still, makes perfect sense to me.

It is always a treat to listen to sir Penrose.

What’s with the 70s cop tv show intro music?

Assuming a somewhat conventional concept of the essence of matter, one could consider for example a theoretical point where angular acceleration meets linear acceleration. I think that the Greeks had difficulty with the concept of something moving in an arc, perhaps because of not yet understanding the concept of multiple forces acting on a particle. When does our conceptual notion of difference become irrelevant to the point that the math seems to be similar? What is the difference between anything and the location at the next measurement? For example, what determines that a change of any type has the ability to take place? This could be a change in position, or rotation, or any change at all. Time could be seen as a form of measurement or limitation to the possibiity of the smallest possible change to the smallest possible particle of matter, if it is indeed possible to define a point in space or time or some other dimensional combination where the concept of matter makes sense. Naturally, matter intuitively makes sense to us and characterizes our understanding of anything because our existence is in a place where space and time define us and our view of what is visible to us physically or in thought. Words fail in an attempt to describe this concept; but it is not impossible to apply some concepts of our own experience to get a better look. Looking at a theoretically small particle, let us call it matter; let us assume that it is at some threshhold of existence where we can define it in thought, and maybe measure something about it. Now place this "particle", or entity, in a multidimensional matrix. Consider how it would be possible for any change at all to enable this particle to retain many of its characterisctics, hopefully enough for our definition to hold, and yet to find itself even the smallest spatial distance from where we first conceived of it. At that point, we can safely build up a comfortable theory that is grounded in the uncertainty principle. That is not, however, satisfying as an explanation of where something is or what it is etc. One thing is fairly certain. Even the things that we do not know about in any way are probably having an effect on us and on everything. I believe that there are probably forces that are buffered as they apply to our experience to the point that they may be immeasurable; yet they are relevant to the bigger picture. Without them, completeness would be impossible. A future implies a present and a past. A location implies other locations. A force implies directionality. Directionality implies forces. Matter seems to imply antimatter, although I am not sure what that really means other than that it is a conceptual question regarding how our minds work and our language fails to convey everything that goes on there. Just some thoughts on a rainy day. Now I wonder whether time could actually be considered as a force.

I'm shocked! What's with the 80's intro music?

There is an argument from simple algebra that the particle ensemble immediately following the Big Bang should not have contained massless particles as the dominant species. If we use Einstein's equation to solve for a referent, or apparent, speed of light- with respect to a traveling particle in the ensemble: then we may derive a parabola similar to the deviations from tensor curvature in observable astronomy data-sets. However, the aeons before and after the Big Bang could then therefore be characterized by the disappearance and re-appearance of massless particles during heating and cooling periods respectively. If this explanation justifies theory with existing data, then there should also be a deviation in the Weyl curvature of light emitted by electron stars, in the form of Cherenkov radiation backscattering in the shape of a halo.
