Thinking Outside the Box, People Like Veneziano, Turok and Penrose

Dark circles indicate regions in space where the cosmic microwave background has temperature variations that are lower than average. The features hint that the universe was born long before the Big Bang 13.7 billion years ago and had undergone myriad cycles of birth and death before that time. See: Cosmic rebirth

Concentric circles in WMAP data may provide evidence of violent pre-Big-Bang activity

Abstract: Conformal cyclic cosmology (CCC) posits the existence of an aeon preceding our Big Bang 'B', whose conformal infinity 'I' is identified, conformally, with 'B', now regarded as a spacelike 3-surface. Black-hole encounters, within bound galactic clusters in that previous aeon, would have the observable effect, in our CMB sky, of families of concentric circles over which the temperature variance is anomalously low, the centre of each such family representing the point of 'I' at which the cluster converges. These centres appear as fairly randomly distributed fixed points in our CMB sky. The analysis of Wilkinson Microwave Background Probe's (WMAP) cosmic microwave background 7-year maps does indeed reveal such concentric circles, of up to 6{\sigma} significance. This is confirmed when the same analysis is applied to BOOMERanG98 data, eliminating the possibility of an instrumental cause for the effects. These observational predictions of CCC would not be easily explained within standard inflationary cosmology.

More on the low variance circles in CMB sky

Abstract: Two groups [3,4] have confirmed the results of our paper concerning the actual existence of low variance circles in the cosmic microwave background (CMB) sky. They also point out that the effect does not contradict the LCDM model - a matter which is not in dispute. We point out two discrepancies between their treatment and ours, however, one technical, the other having to do with the very understanding of what constitutes a Gaussian random signal. Both groups simulate maps using the CMB power spectrum for LCDM, while we simulate a pure Gaussian sky plus the WMAP's noise, which points out the contradiction with a common statement [3] that "CMB signal is random noise of Gaussian nature". For as it was shown in [5], the random component is a minor one in the CMB signal, namely, about 0.2. Accordingly, the circles we saw are a real structure of the CMB sky and they are not of a random Gaussian nature. Although the structures studied certainly cannot contradict the power spectrum, which is well fitted by LCDM model, we particularly emphasize that the low variance circles occur in concentric families, and this key fact cannot be explained as a purely random effect. It is, however a clear prediction of conformal cyclic cosmology.

First Principles by Howard Burton



After returning home from our little vacation, I've hunkered down to read, and I thought this would be a good time to come to know of the Perimeter Institute for Theoretical Physics in Canada and how it started up.

As you know I've linked the Q2c site coming in September as well as I think after ten years this Institute has done a very good job of promoting a science based view toward the latest in the science frontiers.


Mike Lazaridis Donates Additional $50 Million to Perimeter Institute

In his remarks on behalf of the Government of Ontario, The Honourable John Wilkinson, Minister of Research and Innovation said: "Ontario's $3B Innovation Agenda focuses on our government acting as a catalyst to support our top researchers and entrepreneurs - extraordinary people like Mike Lazaridis who are leading the way to turn groundbreaking ideas and innovation into Ontario's next generation of jobs. Ontario's commitment to fundamental and applied research has not only been informed but also inspired by Mike's personal commitment to innovation, and his contributions to the Perimeter Institute. That's why our government has already invested over $65M to support this important initiative. This new investment will strengthen the Institute and the government-industry partnerships that have made it possible, and help us to continue to attract the world-class talent and the scientific knowledge Ontario needs to compete in the 21st century."See: Mike Lazaridis Donates Additional $50 Million to Perimeter Institute


Now you should know that I had received earlier notice of Howard's book from Bee of Backreaction. I have always been under the notion that what can be learnt can be learnt from all ages and there is no one aspect that we can not learn from, when we read and write about the thoughts of bloggers who have something to share with regard to their own journeys.

Bee of Backreaction writes:
The book tells the story of the first years of Perimeter Institute. From Mike Lazaridis' donation, over the search for a name, for a mission, for a location, the joy of building constructions, the hiring of the first faculty members, the establishment of PI's public outreach program, and the successful acquisition of governmental funding, to Howard's departure.

It is very entertainingly written and quite informative in addition, though I admittedly had hoped for more gossip stories about the research and the researchers. The chapter about who talked to whom when and where to pull the strings for governmental support is somewhat lengthy and tiresome, but provides interesting inside views. The book also has an amusing chapter titled "The Trouble with Physicists" about the difficulties in saving scientists from administrating themselves into dysfunctionality. I'm very tempted to quote the funniest paragraphs, but I think you should read the book yourself. It comes with some characterizations of well-known physicists that are quite to the point indeed.

The book is probably more interesting if you know some of the people involved, but besides this it conveys authentically and passionately the fascination, joy and importance of theoretical physics. Overall recommendable. If this was an Amazon review, I'd give 5 stars.
Howard Burton: First Principles


I think this is what I like most that what can be revealed in our blogging encounters, that what was written can go out toward the public to what had be done for me in the exposure of a book. I scoured the bookshop shelves for something interesting to read about science. Of course, in this case it was Howard' Burton's book First Principles.

At 5:18 PM, April 09, 2009, Blogger Plato said...

I have been watch this developing institution as well. In a weird sort of way feeling quite proud that such an institution was given impetus out of which an appreciation for developing of the science perspective was displayed here in the north, by Lazardis

I really don't think it is a Ivory Tower that is being described while Turok resides in his position. Just that what you do as a theorist is brought in line with cosmology. It's much like working the LHC and see that it is working from two perspectives, not just one.

I don't see anything wrong with that.

Nice to see a few prominent names like Susskind, Hawking and Hooft associated with PI.

When I seen the name of the book and the time you spent at PI Howard I was drawn to the idea of what Condense Matter theorists spoke of, in the same way Robert Laughlin looked at how he might describe the "foundational basis" that Phil was talking about.

Witten and others understood the condensed matter point of view as well.

Again I will read the book once finding it.


Best,


Now you must know something about this lay person who writes this blog. Previous to Howard's selective title I came across this term when I was looking for some basis as if in equatorial description that was simple to think it has some relation in algorithmic proportion that this could be the basis of all organization thought that could have exploded amongst the computer world. The very essence and core of our being as it was translated to reveal the very nature of who we are as beings.

This is when I came upon my own "Correlations of Cognition," as the condense matter theorist came to mind. I saw this relevance in how organization could be thought of at a fundamental level. Here in this case, "string theory" held my mind. So when I seen Howard's title of his book it resonated with me, for this is something that had stayed with me for years as I've remained part of the blogging experience of scientists and their engagements with each other.

How is it you then I could not learn to think, that by experiment, that one could line up two counter and oppositional points of view, to see what can be held as truth, and what remains as abstraction of the theoretical division of exploration. You know that what can reside internally as to the mode of operation as to what is self evident(arche), is something that you can place in the external world as well.

So Howard and young students become "mindful of the conduct becoming" and we see this value orientation as to the discussions between scientists. Some students become discouraged and subtle voices strain to speak,"May the ole work horses die?":)

The Book

Anyway I am on page 47 for those readers that have their books. I recognize some aspect of what Mike Lazaridis likes in Howard as to the letter he wrote, preparing the way for his future as to what? I see this fateful discerningly as to a course of action, to much in how after serving their time in the academics, that they must make their way to the financial responsibility toward providing food and sustenance to the family. No fooling around now is there.

So the letter is a spark of genius in terms of putting it out there for hire. Mike Lazaridis recognized something in himself, in what was written by Howard Burton. Mike Lazaridis although an engineer, was was much like him? Avenues to freedom then were the ability to put together a plan once accepting the job, and Howard ability to get to work even though it didn't seem like Howard Burton had a job, was exactly what Mike seem to me what he was looking for.

I liked Chris Isham too, in his explanations, and toward this regard, Chris Isham reminded me of Penrose. I found it kind of odd that later on as Howard is making his way gathering information on Institutes that when again visiting Isham that there was a distance and unknowing attribute of who Howard was? I find this strange when mentioning about his wife and who was meet first as to consequence of saying?

Stargazers and Hill Climbers

AS with Einstein, who was Socrates daemon?:)

In Plato's Apology of Socrates, Socrates claimed to have a daimonion (literally, a "divine something")[6] that frequently warned him - in the form of a "voice" - against mistakes but never told him what to do
See:Fullerane and Allotropes

Some may even call "hills" mountains. Depends on where they think perspective is heighten in relation to where they see themself in the world, and where a better locations allows for a more expansive views of things. This is psychologically important to realize that inherent inside of us if one does follow the tenet of Know Thyself by Socrates. Such a plan would have been understood in the examination to see a relationship in continuity is topologically important with the world around them. Not be self-centred, but to move progressively in the world may call for understanding this relationship with the environment.

What shall proceed the understanding that the arche is fully understood as the central themes of characters, to see it exemplified in how you now approach the world in your own way? It becomes easier for you to understand, that this "imprint of the concrete in the painting I had selected of the Raphael" was to show such a school of thought, was exemplifying the truer principle of the wisdom seeking, while of course approaching the modern day world based on that Socratic method in science.

But I only show by example, and recognizing this facet of the nature of the individual is more the idea that what ever method you choose that it is consistent and recognizable, becomes second nature to the person seeking answers. Student of Science or Philosophy.

Death of Socrates by Jacques Davidthis picture depicts the closing moments of the life of Socrates. Condemned to death or exile by the Athenian government for his teaching methods which aroused scepticism and impiety in his students, Socrates heroicly rejected exile and accepted death from hemlock.

Self portrait of Jacques-Louis David, 1794, Musée du Louvre

Here the philosopher continues to speak even while reaching for the cup, demonstrating his indifference to death and his unyielding commitment to his ideals. Most of his disciplines and slaves swirl around him in grief, betraying the weakness of emotionalism. His wife is seen only in the distance leaving the prison. Only Plato, at the foot of the bed and Crito grasping his master's leg, seem in control of themselves.
See:Jacques-Louis David: The Death of Socrates

I think the idea is and can be unique, in that each can develop a process and means to an end( many travel far and wide while they should have never left home), that would allow this creative aspect of being "in the now" has potential. To be able to allow insight to manifest and spread across the mind in such lightning speed. It thusly leaves no doubt. This is a condensible feature of the complexity of information to be distill to it's essence. IN an abstract world, a rain drop can hold quite an lot of architectural meaning.

For Plato then it was the ideal city-state of Kallipolis

The Philosopher King
Plato defined a philosopher firstly as its eponymous occupation – wisdom-lover. He then distinguishes between one who loves true knowledge as opposed to simple sights or education by saying that a philosopher is the only man who has access to Forms – the archetypal entities that exist behind all representations of the form (such as Beauty itself as opposed to any one particular instance of beauty). It is next and in support of the idea that philosophers are the best rulers that Plato fashions the ship of state metaphor, one of his most often cited ideas (along with his allegory of the cave). "[A] true pilot must of necessity pay attention to the seasons, the heavens, the stars, the winds, and everything proper to the craft if he is really to rule a ship" (The Republic, 6.488d). Plato claims that the sailors (i.e., the people of the city-state over whom the philosopher is the potential ruler) ignore the philosopher's "idle stargazing" because they have never encountered a true philosopher before.


Stargazers by Paul Rossetti Bjarnson, Pg 102, Chapter XV

***


Ever teacher has their progeny of students as has been exemplified in the context of our modern day scholars. Kip Thorne in relation to John Archibald Wheeler. Stephen Hawking and his doctoral students.

Dennis William Siahou Sciama FRS (November 18, 1926–December 18, 1999) was a British physicist who, through his own work and that of his students, played a major role in developing British physics after the Second World War.

Sciama also strongly influenced Roger Penrose, who dedicated his The Road to Reality to Sciama's memory. The 1960s group he led in Cambridge (which included Ellis, Hawking, Rees, and Carter), has proved of lasting influence.


I have already established this lineage and subsequent comments in relation to Penrose under this heading to exemplify the relationship and perspective in relation to each other externally in the progressive nature of moving forward in science.

***


For Plato, it is no less an important feature that at Socrates bedside he sees the wisdom of his teacher become the "guiding light source" of all that must exchange between those who hold a value to "dimensional significance in abstract" in our current day, would be able to see the world in a most significant way. It's no less progressive then, that such an example was given to an extent that the thought process of the Gendankin, would be set before Plato's own students, as John Wheeler did for his, to see that Aristotle is most selectively announced as a most brilliant student by answering to Plato's analogy of the Cave. Who becomes an extension of the "arche in principle" as one end being science, and in a open sweeping hand, to all that is for ever exemplify in the "arche contained" in the heading of this blog above.

Plotinus

Plotinus (Greek: Πλωτῖνος) (ca. AD 204–270) was a major philosopher of the ancient world who is widely considered the founder of Neoplatonism (along with his teacher Ammonius Saccas). Much of our biographical information about him comes from Porphyry's preface to his edition of Plotinus' Enneads.

Plotinus Theory

Plotinus taught that there is a supreme, totally transcendent "One", containing no division, multiplicity or distinction; likewise it is beyond all categories of being and non-being. The concept of "being" is derived by us from the objects of human experience called the dyad, and is an attribute of such objects, but the infinite, transcendent One is beyond all such objects, and therefore is beyond the concepts that we derive from them. The One "cannot be any existing thing", and cannot be merely the sum of all such things (compare the Stoic doctrine of disbelief in non-material existence), but "is prior to all existents". Thus, no attributes can be assigned to the One. We can only identify it with the Good and the principle of Beauty. [I.6.9]

For example, thought cannot be attributed to the One because thought implies distinction between a thinker and an object of thought (again dyad). Even the self-contemplating intelligence (the noesis of the nous) must contain duality. "Once you have uttered 'The Good,' add no further thought: by any addition, and in proportion to that addition, you introduce a deficiency." [III.8.10] Plotinus denies sentience, self-awareness or any other action (ergon) to the One [V.6.6]. Rather, if we insist on describing it further, we must call the One a sheer Dynamis or potentiality without which nothing could exist. [III.8.10] As Plotinus explains in both places and elsewhere [e.g. V.6.3], it is impossible for the One to be Being or a self-aware Creator God. At [V.6.4], Plotinus compared the One to "light", the Divine Nous (first will towards Good) to the "Sun", and lastly the Soul to the "Moon" whose light is merely a "derivative conglomeration of light from the 'Sun'". The first light could exist without any celestial body.


While the arche then becomes a understanding and significant addition to ever place that self evident becomes real for the individual then how is it that such an relation cannot be seen in the world as a foundation principle to guarantee that they are on the right track. To see that "correlation of cognition" places a role in the factual attainment of information. No matter how insignificant or trivial the relation, as common knowledge, it becomes a reinforcing measure of how one is adapting and applying this model, which allows confidence to be built in pursuance of knowledge and truth.

The Plane of Simultaneity

This blog entry was constructed to reply to the conversation that is going on in the issue of the "Block Universe."


See:

  • Penrose and Quanglement

  • Entanglement and the New Physics




  • In the past, teleportation has only been possible with particles of light Image: Rainer Blatt



    It's useless sometimes to just lay there while these thoughts accumulate in one's mind, as one weaves together the picture that is forming, and whence it come from this unification process, and after a time, one then thinks about the abilities of mind to gather and consolidate.


    By taking advantage of quantum phenomena such as entanglement, teleportation and superposition, a quantum computer could, in principle, outperform a classical computer in certain computational tasks. Entanglement allows particles to have a much closer relationship than is possible in classical physics. For example, two photons can be entangled such that if one is horizontally polarized, the other is always vertically polarized, and vice versa, no matter how far apart they are. In quantum teleportation, complete information about the quantum state of a particle is instantaneously transferred by the sender, who is usually called Alice, to a receiver called Bob. Quantum superposition, meanwhile, allows a particle to be in two or more quantum states at the same time


    So let me begin first by saying that given this process we can connect this world line across the expanse of space, is, more or less the understanding that this is to be the means in which these new forms of communication in science are leading as we expound the future, and what it shall become in our present moments.



    See: Central theme is the Sun You can "click" on picture as well, or, use mouse to hover over image, for additional reading

    So you look at the sun, and what new ways can we can perceive and accumulating the data of what connects this "distance and time," one will be all the smarter when they realize that the results of experimental verifications are at present being given, and as such, what shall these examples serve, but to remind one that new experiences continue to bring new innovations to the forefront.

    Lightcone Projection- see mathematical basis here for the introduction of what will become the basis of determinations, the "decomposable definition" of these new forms of communication.

    The basis for these thoughts are the developing views based on the light cone. It was not my reasons alone in which such an idea was used to support an conjecture about, so, by these very reasons I thought it best to explain what such simultaneity can do as we hold these views about "distance and time" as we follow this world line across the expanse of the universe.

    The grey ellipse is moving relativistic sphere, its oblate shape due to Lorentz contraction. Colored ellipse is visual image of the sphere. Background curves are a xy-coordinates grid which is rigidly linked to the sphere. It is shown only at one moment in time.See here for reference and animations.

    Okay, so we have this event that happens in time. How are we to measure what the sun is suppose to be, if we did not have some information about the depth of perception that is needed in order to create this image for consumption?

    Such comparative views are needed that are current, and, "in experimental stages" to help us discern what it means for "Galactic Communication" which we will employ as we measure the distance of this world line.:)

    Such distances "can be elevated in my view," and such instantaneous recognitions are to be the associative values I place on how we can now see the "bulk perspective" and the graviton's condensation we can now assign to the cosmos?

    As we know from Einstein’s theory of special relativity, nothing can travel faster than c, the velocity of light in a vacuum. The speed of the light that we see generally travels with a slower velocity c/n where n is the refractive index of the medium through which we view the light (in air at sea level, n is approximately 1.00029 whereas in water n is 1.33). Highly energetic, charged particles (which are only constrained to travel slower than c) tend to radiate photons when they pass through a medium and, consequently, can suddenly find themselves in the embarrassing position of actually travelling faster than the light they produce!

    The result of this can be illustrated by considering a moving particle which emits pulses of light that expand like ripples on a pond, as shown in the Figure (right). By the time the particle is at the position indicated by the purple spot, the spherical shell of light emitted when the particle was in the blue position will have expanded to the radius indicated by the open blue circle. Likewise, the light emitted when the particle was in the green position will have expanded to the radius indicated by the open green circle, and so on. Notice that these ripples overlap with each other to form an enhanced cone of light indicated by the dotted lines. This is analogous to the idea that leads to a sonic boom when planes such as Concorde travel faster than the speed of sound in air
    See:What is Cerenkov Radiation?

    It is thusly, that such events in time produce information for us, that help us to look at the universe in new ways, and as such, information can be used to build new devices that penetrate beyond the confines we finds photons experience in their limitations.( please Phil take note of, in bold)

    Numerical Relativity and the Human Experience?

    "I’m a Platonist — a follower of Plato — who believes that one didn’t invent these sorts of things, that one discovers them. In a sense, all these mathematical facts are right there waiting to be discovered."Donald (H. S. M.) Coxeter


    I contrast the nature of Numerical Relativity to the computer and the way we would think human consciousness could have been linked in it's various ways. Who hasn't thought that the ingenuity of the thinking mind could not have been considered the Synapse and the Portal to the thinking Mind?:)

    Also think about what can be thought here as Gerardus t" Hooft asked as to think about in the limitations of what can be thought in relation to computerizations.

    There is something to be said here about what conscious is not limited too. It is by it's very nature "leading perspective" that we would like to have all these variables included in or assertions of what we can see while providing experimental data to the mind set of those same computerization techniques?

    Numerical Relativity Mind Map

    So we of course like to see the mind's ingenuity( computerized or otherwise) when it comes to how it shall interpret what is the road to understanding that gravity is seen in Relativities explanation.

    Source:Numerical Relativity Code and Machine Timeline


    It is a process by which the world of blackholes come into viewing in it's most "technical means providing the amount of speed and memory" that would allow us to interpret events in the way we have.

    The information has to be mapped to computational methodology in order for us to know what scientific value scan be enshrined in the descriptions of the Blackhole. Imagine that with current technologies we can never go any further then what we can currently for see given the circumstances of this technology?


    Source:Expo/Information Center/Directory-Spacetime Wrinkles Map

    So on the one hand there is an "realistic version" being mapped according to how we develop the means to visualize of what nature has bestowed upon us in the according to understanding Blackhole's and their Singularities.

    Numerical Relativity and Math Transferance

    Part of the advantage of looking at computer animations is knowing that the basis of this vision that is being created, is based on computerized methods and codes, devised, to help us see what Einstein's equations imply.

    Now that's part of the effort isn't it, when we see the structure of math, may have also embued a Dirac, to see in ways that ony a good imagination may have that is tied to the abstractions of the math, and allows us to enter into "their portal" of the mind.

    NASA scientists have reached a breakthrough in computer modeling that allows them to simulate what gravitational waves from merging black holes look like. The three-dimensional simulations, the largest astrophysical calculations ever performed on a NASA supercomputer, provide the foundation to explore the universe in an entirely new way.

    Scientists are watching two supermassive black holes spiral towards each other near the center of a galaxy cluster named Abell 400. Shown in this X-ray/radio composite image are the multi-million degree radio jets emanating from the black holes. Click on image to view large resolution. Credit: X-ray: NASA/CXC/AIfA/D.Hudson & T.Reiprich et al.; Radio: NRAO/VLA/NRL

    According to Einstein's math, when two massive black holes merge, all of space jiggles like a bowl of Jell-O as gravitational waves race out from the collision at light speed.

    Previous simulations had been plagued by computer crashes. The necessary equations, based on Einstein's theory of general relativity, were far too complex. But scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., have found a method to translate Einstein's math in a way that computers can understand.


    Quantum Gravity

    Now their is a strange set of circumstance here that would leave me to believe, that the area of quantum gravity has lead Numerical Relativity to it's conclusion? Has the technology made itself feasible enough to explore new experimental data that would allow us to further interpret nature in the way it shows itself? What about at the source of the singularity?

    See: Dealing with a 5D World

    I would not be fully honest if I did not give you part of the nature of abstract knowledge being imparted to us, if I did not include the "areas of abstractness" to include people who help us draw the dimensional significance to experience in these mathematical ways. It is always good to listen to what they have to say so that we can further developed the understanding of what becomes a deeper recognition of the way nature unfolds of itself.

    There are two reasons that having mapped E8 is so important. The practical one is that E8 has major applications: mathematical analysis of the most recent versions of string theory and supergravity theories all keep revealing structure based on E8. E8 seems to be part of the structure of our universe.

    The other reason is just that the complete mapping of E8 is the largest mathematical structure ever mapped out in full detail by human beings. It takes 60 gigabytes to store the map of E8. If you were to write it out on paper in 6-point print (that's really small print), you'd need a piece of paper bigger than the island of Manhattan. This thing is huge.
    Emphasis and underlined, my addition.

    Computer Language and Math Joined from Artistic Impressionism?

    Most people think of "seeing" and "observing" directly with their senses. But for physicists, these words refer to much more indirect measurements involving a train of theoretical logic by which we can interpret what is "seen."- Lisa Randall



    THOMAS BANCHOFF has been a professor of mathematics at Brown University in Providence, Rhode Island, since 1967. He has written two books and fifty articles on geometric topics, frequently incorporating interactive computer graphics techniques in the study of phenomena in the fourth and higher dimensions


    The marriage between computer and math language(Banchoff) I would say would be important from the prospective of displaying imaging, seen in the development of abstract language as used in numerical relativity? Accummalated data gained from LIGO operations. Time variable measures?

    Blackhole Information Paradox

    What good is a universe without somebody around to look at it?
    Robert Dicke


    John Archibald Wheeler (born July 9, 1911) is an eminent American theoretical physicist. One of the later collaborators of Albert Einstein, he tried to achieve Einstein's vision of a unified field theory. He is also known as the coiner of the popular name of the well known space phenomenon, the black hole.

    There is always somebody who is the teacher and from them, their is a progeny. It would not be right not to mention John Archibald Wheeler. Or not to mention some of his students.

    Notable students
    Demetrios Christodoulou
    Richard Feynman
    Jacob Bekenstein
    Robert Geroch
    Bei-Lok Hu
    John R. Klauder
    Charles Misner
    Milton Plesset
    Kip Thorne
    Arthur Wightman
    Hugh Everett
    Bill Unruh



    COSMIC SEARCH: How did you come up with the name "black hole"?

    John Archibald Wheeler:It was an act of desperation, to force people to believe in it. It was in 1968, at the time of the discussion of whether pulsars were related to neutron stars or to these completely collapsed objects. I wanted a way of emphasizing that these objects were real. Thus, the name "black hole".

    The Russians used the term frozen star—their point of attention was how it looked from the outside, where the material moves much more slowly until it comes to a horizon.* (*Or critical distance. From inside this distance there is no escape.) But, from the point of view of someone who's on the material itself, falling in, there's nothing special about the horizon. He keeps on going in. There's nothing frozen about what happens to him. So, I felt that that aspect of it needed more emphasis.


    It is important to me to understand some of the history of the Blackhole, and the students who went on to develop the very ideas around them. To see how they interconnect at one time or another, to provide for the very insights from such gatherings.




    Stephen Hawking’s says:

    “Roger Penrose and I worked together on the large scale structure of space and time, including singularities and black holes. We pretty much agree on the classical theory of theory of relativity but disagreements began to emerge when we got into quantum gravity. We now have different approaches to the world, physical and mental. Basically, he is a Platonist believing that’s there’s a unique world of ideas that describes a unique physical reality. I on the other hand, am a positivist who believes that physical theories are just mathematical models we construct, and it is meaningless to ask if they correspond to reality; just whether they predict observations.”
    ( Chapter Six-The Large, the Small and the Human Mind-Roger Penrose-Cambridge University Press-1997)
    See: Phil Warnell's comment.

    Black hole information paradox


    Whereas Stephen Hawking and Kip Thorne firmly believe that information swallowed by a black hole is forever hidden from the outside universe, and can never be revealed even as the black hole evaporates and completely disappears,

    And whereas John Preskill firmly believes that a mechanism for the information to be released by the evaporating black hole must and will be found in the correct theory of quantum gravity,

    Therefore Preskill offers, and Hawking/Thorne accept, a wager that:

    When an initial pure quantum state undergoes gravitational collapse to form a black hole, the final state at the end of black hole evaporation will always be a pure quantum state.

    The loser(s) will reward the winner(s) with an encyclopedia of the winner's choice, from which information can be recovered at will.

    Stephen W. Hawking, Kip S. Thorne, John P. Preskill
    Pasadena, California, 6 February 1997


    Drawing Credit: XMM-Newton, ESA, NASA-Image sourced from: Pictured above is an artist's illustration of a black hole surrounded by an accretion disk.

    The black hole Information Paradox results from the combination of quantum mechanics and general relativity. It suggests that physical information could "disappear" in a black hole. It is a contentious subject since it violates a commonly assumed tenet of science—that information cannot be destroyed. If it is true, then cause and effect become unrelated, and nothing science knows, not even our memories, can be trusted.

    A: According to the orthodox view of quantum mechanics, called the Copenhagen interpretation, a system (represented here by a child’s block) does not occupy a definite state or location until it is measured. Before then it is just a blur of overlapping possibilities.

    B: The many worlds interpretation insists that the system occupies all its possible states but that every one of them exists in its own alternate universe. Each universe sees one state only, which is why we never observe the block in two states at once.

    C: In Penrose’s interpretation, gravity holds our reality together. In each potential state, the block generates a separate gravitational field. Over time, the energy required to maintain these multiple fields causes the block to settle into one state only—the one that we observe.

    "In Penrose’s interpretation, gravity holds our reality together. In each potential state, the block generates a separate gravitational field.....," rings with a certain importance when one talks about what happens with the very nature of the blackhole. What happens to that information.

    Phil Warnell:However, if the second is taken as truth and all is remembering, then what can the force of gravity do to a memory that is not in any, yet of all?

    I tried to implement a method by which one could "gauge the significance of the emotive experience" as it may pertain to that "primitive part" of our nature. That we could see "remembering" had been assigned a "quantum reductionist state" within the confines of that methodology?

    See:Quantum State reduction as a real phenomenon by Roger Penrose (Oxford)2 Sep 1999

    "The block," while holding different gravitational defined consciousness states, had to settle to a strong emotive consolidating force from that experience. You repeatedly relive the experience, while current information saids that the memory can change. See Ledoux.

    Big Bang:One Man's Change of Heart

    Thanks Paul

    One definitely needs some perspective around this and how such information is given. I refer here for consideration, about perspective, and how it can be exploited for further consideration on what is emitted, and what manifests in weak gravitational field measure, as neutrino effects(quantum gravity).

    Microperspective and methods of examination, raise the issue fo cerenkov radiation and what it tells us about such interactive phases?

    Here in refractive consideration, ICECUBE, paints a different picture of what began somewhere else in cosmological high energy collisions. "Neutrinos and strangelets" are part of the developing scenario with which the universe has consequences, if held to the initial conditons of our universe. You had to know where to look for these.

    Plato:
    "Nothing" in stated form was and always is "nothing" which would have not allowed any further discussion. "Zero" in our conversation is a much different kind of thinking. I understood that as well. "Zero" would have been the equivalent to "i" in the Dirac's matrices?



    Physics at this high energy scale describes the universe as it existed during the first moments of the Big Bang. These high energy scales are completely beyond the range which can be created in the particle accelerators we currently have (or will have in the foreseeable future.) Most of the physical theories that we use to understand the universe that we live in also break down at the Planck scale. However, string theory shows unique promise in being able to describe the physics of the Planck scale and the Big Bang.


    I wanted to add this post, and to centralize some references that were found that helped form my perspective on "nothing." What! I guess I'm done?:)

    Seriously, this had to be confronted, and who better then from our layman perspectve, then the admission of a leaders in science, who can change theirs mind after some thinking?

    Lubos shares his perspective on linked section of titled paper above.

    One interpretation of the coupling of Wheeler-DeWitt functions is that it originates from topology changing effects. Topology change seems to be inevitable in quantum gravity. To treat topology change properly is a very complicated calculation using today’s mathematical tools.


    I wanted to add these links here for consideration, as well what link given by Paul for consideration in regards to Penrose, the figure of the man's change of heart that ighlight's this post. In Phase transitions the comments have been quite enlightening.

    Think Math


    Nature's patterns
    So who is right? Well, there is much that is attractive in the Platonist point of view. It's tempting to see our everyday world as a pale shadow of a more perfect, ordered, mathematically exact one. For one thing, mathematical patterns permeate all areas of science. Moreover, they have a universal feel to them, rather as though God thumbed His way through some kind of mathematical wallpaper catalogue when He was trying to work out how to decorate His Universe. Not only that: the deity's pattern catalogue is remarkably versatile, with the same patterns being used in many different guises. For example, the ripples on the surface of sand dunes are pretty much identical to the wave patterns in liquid crystals. Raindrops and planets are both spherical. Rainbows and ripples on a pond are circular. Honeycomb patterns are used by bees to store honey (and to pigeonhole grubs for safekeeping), and they can also be found in the geographical distribution of territorial fish, the frozen magma of the Giant's Causeway, and rock piles created by convection currents in shallow lakes. Spirals can be seen in water running out of a bath and in the Andromeda Galaxy. Frothy bubbles occur in a washing-up bowl and the arrangement of galaxies.


    Well the following article came to my recognition by the "picture above". When reference was made to what some might think, as what underlying reality exists as a mathematical pattern, could ever been associated to some divine will? Who or what would decide this, as representing the very idea of resonant possibilties of expression in symmetry breaking?

    But crystals exhibit clear mathematical patterns of their own, such as a regular geometric form, and while nobody can deduce this in full logical rigour from the quantum mechanics of their atoms, there is a chain of reasoning that makes it plausible that the laws of quantum mechanics do indeed lead to the regularities of crystal structure.


    How would one define a crystal, as having preconcieved viabilties in the quantum world? This would be very hard and uncertain thing to deal with. What rational would allow such previews of a reality before it can become something else?

    Science and the Mind: Sir Roger Penrose



    Above picture, belongs to this article and titled above, of frames that Sir Roger Penrose wrote in 1999.

    Roger Penrose, a professor of mathematics at the University of Oxford in England, pursues an active interest in recreational math which he shared with his father. While most of his work pertains to relativity theory and quantum physics, he is fascinated with a field of geometry known as tessellation, the covering of a surface with tiles of prescribed shapes.


    Being reminded of Roger Penrose I am actually going to contribute this blog entry to him, and sources that I had collected.

    Twistor Theory


    The motivation and one of the initial aims of twistor theory is to provide an adequate formalism for the union of quantum theory and general relativity. Twistors are essentially complex objects, like wavefunctions in quantum mechanics, as well as endowed with holomorphic and algebraic structure sufficient to encode space-time points. In this sense twistor space can be considered more primitive than the space-time itself and indeed provides a background against which space-time could be meaningfully quantised.

    In the past 30 years a lot of work has been done on developing twistor theory. Its creator, Roger Penrose, was first led to the concept of twistors in his investigation of the structure of spacetime and it was he who first saw the wide range of applications for this new mathematical construct. Yet 30 years later, twistors remain relatively unknown even in the mathematical physics community. The reason for this may be the air of mystery that seems to surround the subject even though it provides a very elegant formalism for both general relativity and quantum theory. These notes are based on a graduate lecture course given by R. Penrose in Mathematical Institute, Oxford, in 1997 and should give a brief introduction to the basic definitions. Let us begin with the building blocks: spinors.
