Before indicating how the string LQG link might happen, here is the problem I have. I can put on the string theory "hat" and work there or read papers related to that. The structures are vast and rich. Witten's find that the S-matrix theory is a flat space limit of a holographic principle, or the Maldecana AdS/CFT correspondence and so forth contain rich structure which are too physically apparent. On the other hand I can put on a loop variable hat and see how the close correspondence with basic general relativity is such that this structure also must have some bearing on nature. There is also twistor theory as well.

The Sen connection in LQG and the "charge" due to the electric-like field is a constraint in LQG which is sentisive to the same quantum phase transition as the is field flux on AdS_4xD7 which sets the cosmological constant. The Barbero-Immirzi ambiguity stems from a gauge fixing problem. It is possible that this stting of the net charge Q = nalba E, on the manifold removes this ambiguity. This produces an additional constraint in LQG that might be used to cure the B-I ambiguity.

Hi Florin. This is a very important/relevant question.

How do you see the following as applicable to, and substantiated by, your essay:

The ability of thought to describe or reconfigure sensory experience is ultimately dependent upon the extent to which thought is similar to sensory experience.

That statement is clear enough. If you think that the above statement is not true, then please clearly explain why you believe that this is so.

Thanks.

Hi Frank,

There are two kinds of learning: supervised and unsupervised. Suppose I take a young child and show him a chair. I say: this is a chair. Then the child learns in a supervised manner. Suppose also I show him the color red. I say: this is the color red. On one hand this is also supervised learning, but since I cannot really know how the child is actually seeing the color, learning the color perception is unsupervised learning.

Then this begs the question: is my color red the same as your color red? For most people we know it is, but for color blind people is not. The reason it is not is because they are missing one or two color receptors in their eyes. The color perception depends on the dimensionality of the receptor and this is very reminiscent of quantum mechanics.

Now to answer your question. The brain naturally evolves towards identical perceptions and this given by the general topology of the neuron connection. With similar connection patterns, self-feedback unsupervised learning leads to the same eigenvalues modes of representing information for all people. That is why we all see red as red, and my red is the same as yours. The way the neurons are connected, and the tools of analyzing information (like the number and type of color receptors) determine critically the outcome of measurement. Same in quantum mechanics: what I observe in a double slit experiment depends if I put polarizers to determine the "which path" or not. But regardless of the tools we use to interpret the world, there are precise mathematical predictions we can make about the world like quantum mechanics and relativity.

I hope this answer your question, if not, please feel free to ask additional questions.

Florin, you didn't answer the question. The question was: Do you agree that the following is a fact:

"The ability of thought to describe or reconfigure sensory experience is ultimately dependent upon the extent to which thought is similar to sensory experience."

Stefan says: "It seems to me that an intuitive description of ultimate reality must at first place have an overall consistence that, for all practical purposes in the universe we live in, at least seems to be the ultimate truth."

I say: "The fundamental laws of physics must be unified and also understood in a fashion that allows life and experience (in general) to be. Consistent with this, dream experience is essential to the proper (and complete) understanding of both life and experience in general."

The fundamentally interactive nature of being, experience, and thought is undeniable Florin, as follows in this post:

As I said: The ability of thought to describe or reconfigure sensory experience is ultimately dependent upon the extent to which thought is similar to sensory experience.

Dreams make sensory experience in general (including gravity and electromagnetism) more like thought. Accordingly, the unification of Maxwell's and Einstein's theories (in a fourth spatial dimension) is plainly and significantly evident in/as the dream. Dreams involve a fundamental integration and spreading of being and experience at the [gravitational] mid-range of feeling BETWEEN thought AND sense. Dreams add to the integrated extensiveness of being, experience, and thought in and with time.

The natural and integrated extensiveness of being and experience go hand-in-hand -- in and with time as well. I have proven this definitively. Witness the following:

Dreams are an emotional experience that occur during the one third of our lives that we spend sleeping, because emotion is one part (or one third) of feeling, emotion, and thought. Consistent with this, both feeling and thought are proportionately reduced in the dream. Thoughts and emotions are differentiated feelings. Dreams are essential for thoughtful and emotional balance, integration, comprehensiveness, consistency, and resiliency. Indeed, emotion that is comprehensive and balanced advances consciousness. If the self did not represent, form, and experience a comprehensive approximation of experience in general, we would be incapable of growth and of becoming other than we are.

The totality of the system/experience has to be considered Florin.

How do you account for the union of gravity and electromagnetism/light in a fourth dimension of space Florin? Do you agree with this: "The fourth dimension must be understood as additive (in regard to space) as well as being subtractive (on balance) as well." How would you account for this?

The self, represents, forms, and experiences a comprehensive approximation of experience in general. Also, the self represents, forms, and experiences comprehensive approximations of experience in general. If the self did not represent, form, and experience a comprehensive approximation of experience in general, we would be incapable of growth and of becoming other than we are.

The 4th space dimension gives us Einstein's theory of gravity (general relativity) AND electromagnetism (Maxwell's theory of light). We know this.

Moreover, it is common sense that this union is plainly and obviously evident in our experience.

1) I have demonstrated a comprehensive union and balancing of gravity and electromagnetism/light.

2) Dreams improve upon the integrated extensiveness of experience and thought.

3) Dreams involve a fundamental integration and spreading of being and experience at the MID-RANGE of [gravitational] feeling between thought AND sense.

4) Dreams make thought more like sensory experience in general (including gravity and electromagnetism).

5) The ability of thought to describe or reconfigure sense is ultimately dependent upon the extent to which thought is similar to sense.

My understanding/description of how the dream constitutes the union of gravity and electromagnetism/light is complete, fundamental, simple, comprehensive, and consistent. It is lacking nothing.

See: The Dream Fundametally Balances and Unifies Gravity and Electromagnetism

http://radicalacademy.com/studentrefphilfmd13.htm

I have even mathematically demonstrated/proven it in a fundamental fashion; as I have shown the three to one (one third) relation of BOTH space (the three space dimensions in relation to the 4th space dimension) AND time (3 to 1 in Einstein's theory of gravity) in dreams; as dreams occur during the one third of our lives that we spend sleeping. Or, you could say that the extension in space (three to one, or one third) is consistent with extension in time. Note: there are three parts of time as well -- past, present, future.

Electromagnetism/light and gravity are fundamental to life. They are united in the dream. The totality of experience has to be considered.

To think that the union between Einstein's theory of gravity and electromagnetism (i.e., Maxwell's theory of light) is not plainly and significantly obvious/manifest in our experience is one of the greatest blunders regarding lack of common sense that I have ever seen.

Electromagnetism involves extremes of feeling, brightness, visibility, size, and energy. Gravity and electromagnetism/light are united at the [gravitational] mid-range of feeling between thought and sense. When scale is balanced, gravity is repulsive and attractive as electromagnetic energy/light and feeling. I have demonstated all of this in/as the dream.

Demonstrate gravity as attractive and repulsive -- in keeping with relatively constant (and proper) lighting, energy, and brightness -- in a space that is at once understood to be larger and smaller. The space must also be invisible and visible at once. I have demonstrated ALL of this in/as dream experience.

How do you get around all of this Florin?

You now have electromagnetism/light as gravitational space. Space manifesting as BOTH gravitational AND electromagnetic/light energy. (Constant energy as well.)

The union of gravity and electromagnetism/light in a fourth spatial dimension completes, balances, and extends Einstein's theory. (Don't forget, Einstein's theory is incomplete, as it shows that space/the universe is EITHER expanding OR contracting.) It demonstrates thought that is more like sensory experience in general. The ability of thought to describe or reconfigure sense is ultimately dependent upon the integrated extensiveness of thought, experience, and being. Indeed, the ability of thought to describe or reconfigure sense is ultimately dependent upon the extent to which thought is similar to sensory experience. Dreams make thought more like sensory experience in general. Dreams involve a fundamental integration and spreading of being and experience (including thought) at the mid-range of feeling BETWEEN thought AND sense.

FLORIN, YOUR IDEAS DO NOT ACCOUNT FOR ANY OF THIS.

I have unified gravity and electromagnetism/light in and with time. How does your essay relate to this?

Frank,

Sorry if I was not clear. Let me try again. You state:

"The ability of thought to describe or reconfigure sensory experience is ultimately dependent upon the extent to which thought is similar to sensory experience."

I am not sure about the reconfigure part, but I do agree with the rest of the statement with the exception of "ultimately". Yes, sensory experience is very important, but we cannot deny the ability of mathematics to describe not only the experiences we do not directly encounter but even the ones we do. In other words, although I agree it is very important, I do not grant to the sensory experience.

However, I had a second question, relating to what happen before the first dream. Were gravity and electromagnetism unified then? In my opinion this is a show stopper issue and if this point is not addressed, the rest of the discussion degenerates into parallel monologues.

Sorry, but some formatting commands erased a key word. Here is my post again.

Hi ,

No Very easy in fact ,I understand speedly,maths ,physics ,sciences are for me like plant a flower ,I think all is there ,when you like sciences ,too speedly for some people ,but it's like that .

I beleivewhat you need to be more pragmatic in physics I think ,I invite you to insert limits .In all case congratulations,I think what Lawrence can help you in math and Ray in physics .The complemenatrity Florin ,always .

Best regards

Dear Florin,

You see, historically, axiomatization *always* came *after* at least a crude version of the corresponding (formal) model was in place. This is simply because you have to have *something* that you want to axiomatize *before* you can actually axiomatize it.

To axiomatize a system of knowledge is to show that its claims can be derived from a small, well-understood set of sentences (the axioms). There are typically multiple ways to axiomatize a given mathematical domain.

Physics is not a 'mathematical domain', so you must be attaching an entirely new meaning to the term 'axiomatization'. If, indeed, this is so, what kind of meaning do you attach to that term?

Lev,

Indeed one can axiomatize a given domain in many ways. Special relativity can be axiomatized in at least 3 ways, quantum mechanics in at least 10. What I am doing is to try to solve Hilbert's sixth problem. And we do have this "something": it is our physical reality.

You are right about the fact the physics is not a 'mathematical domain', and this is precisely the reason why physics axiomatization resisted many attempts at solving it, starting with Hilbert himself. As I am showing in my essay you do not do the axiomatization directly, but indirectly via finding the "requirements" of nature. It is absolutely remarkable that we have already solid mathematical proofs about the uniqueness of various parts of reality. What I am doing is taking a leap of faith and speculating that all of physics can be obtained in this way. This is not the old fashion mathematical axiomatization, but a generalization of the concept and you do get rigorous uniqueness results out of it. There are additional preliminary results showing that at least in the case of the Standard Model we should be very optimistic.

If in the end we manage to mathematically prove that our universe cannot be except the way it is: with 3 spatial dimensions, with time, with quantum mechanics, with the Standard model, etc, then we should be able to claim that whatever mechanism we use for this proof deserves to be called axiomatization of physics, although technically it is not the standard mathematical definition.

I highly suspect (but with no mathematical proof yet) that Gordon McCabe is right in his duality hypothesis between math and reality. If true, my heuristic rule should cut both ways and describes mathematics as well: math is the collection of domains that are locally consistent, isolated, and with finite algorithmic information theory content. If nature is relational at core, the platonic world of math and reality are nothing but the two aggregation states of those relational structures.

Dear readers,

I do not see the critique of essay. It is not a forum for cosmetics and women, it is a forum for physics! If you rate an essay, it means that you read and understand the essay. Therefore, please publish your opinion and critique of the essay. We do not write holy papers, all essays have errors.

Why all physicists are afraid of criticism? I'm sure it is the main cause of the crisis in science. Every year a lot of papers are published but a little critique appears only. The false theories will grab all the world without critique!

Florin,

It is difficult for me to understand how a chosen model of an evolving physical universe becomes both the truth recorder and the truth predictor of that physical universe. Is a theory of everything also an explanation of everything? Where is the axiom of creation? How did the things observed become the things observed?

I do applaud your approach. It certainly would bring us closer to a categorical understanding of our environment that could then be mathematically manipulated to predict statistical magnitudes of possibility for the occurance of an observed event that is actually not observed. Would all of humanity therefore find themselves more confident of surviving their own futures? Sorry, it's that missing link between recorder and predictor that keeps me confused.

Perhaps humanity will eventually satisfy itself with mathematical proofs for experiencing reality instead of actually sensing it. Certainly it would remove the risks of making decisions and then having to survive the consequences within a sensory reality that could include the serious injury or death of the decision maker. It think you could be leading us to a new dimension for human experience and responsibility so I also applaud your courage in taking us there.

Irvone,

Please see the attachment on my post on Aug. 21, 2009 @ 01:27 GMT. This contains an extended version of the essay with additional sections which did not make it in the official entry because of the very strict character limit of the contest. Please read the second additional section on a possible mathematical approach to the problem of creation.

To me the core critical question is to what degree were God's hands tied at the moment of creation? Did he have any freedom in making our universe any different the way it is today? Could we live in a universe without quantum mechanics, or time, or the Standard Model, or can we mathematically prove there was no other way possible?

A theory of everything is not likely will explain all. Physics will be more like medicine: we know the bones, the circulatory system, the muscles, etc, but we are still battling cancer. Once we know the general framework of nature and we can mathematically prove their necessity, there will always be secondary and tertiary phenomena to be explained. Let me give you an example. Light propagation in optical fibers obeys Maxwell's equations which are known for a very long time. Still, from them in a certain approximation one deduce the nonlinear Schrodinger equation which exhibits solitonic solutions and the full understanding of this equation involves very complicated and different math than the original Maxwell's equations.

Leshan,

I did not see a criticism of my essay in your post either. Do you have any comments or questions about it?

Let me poke holes in your entry as well. You cannot remove space time from a region because any tools you can use they can exist only in space time themselves. The only possibility is that your space-time vacuum appears by itself, but you cannot control or detect it. You may disagree on the detection part, but how can you tell apart a change in clock rate from the effects of a gravitational wave or simply from a local curvature of space time generated by mass? You can only tell it apart from normal curvature by violations of the equivalence principle.

Who knows, maybe near your perfect vacuum, left and right shoes do fall differently. (That was a joke, I could not help it.)

Florin,

'You cannot remove space time from a region because any tools you can use they can exist only in space time themselves'.

To create an absolute vacuum, we must remove all the matter very quickly (instantly) from the region. For this purpose I can use some nuclear processes where particles disappear instantly. For example at annihilation (decay) both particles disappear instantly due to a hole must appear. A hole is the absence of extension and duration, therefore external observer must detect time dilation and length contraction.

Thus, if the clocks near atomic station will tick slower than control clocks, it will be the experimental proof for my hole theory.

Another proof: near massive bodies also appear time dilation and length contraction. Thus, gravitation have the hole nature; massive bodies emit holes!

About 'left and right shoes do fall differently'. The purpose of forum is analysis and critique of essays, but I don't found ever a critique. Women praise and rate a '10' its essay without reading and understanding it.Therefore I published my review.

Florin,

It could just as well be argued that physics and cosmology requires some insight into a new physical principle. This will remove an obstruction in our current understanding of thing --- think of throwing out excess baggage.
