Dear Dr. Gibbs,

after a second try I still have to admit not to understand most of your certainly excellent statements. It is a fact that mathematical constructs are difficult to translate into comprehensible physical meaning. Or, is it a trick to confuse those with a desire to understan?

Anyway, the theoreticians have an easy life. Nobody can refute your theories such as multiverses since there are no empirical facts. It sounds to me more like philosophy or clairvoyance.

I wish you good luck with your further work

Susanne, the audience here has a wide range of levels of expertise so it is difficult to get it right for everyone. I have never seen these essays as an exercise in science popularization, but I have not included any equations as some people do here. That is my best compromise. I want to say something substantive to people who are familiar with the subject. If I did not mention the specific concepts I am referring to everything would be too vague, and if I attempted to explain them for those less familiar the essay would be ten times as long. Any of the terms used can be skipped and just accepted as something you don't know about, or they can be looked up. I hope you managed to get something out of it.

The topic for this essay is deeply philosophical so I make no apologies for the fact that my essay is philosophical and meta-physical. This kind of thinking is very important at the frontiers of theoretical physics where strongly help assumptions sometimes need to be given up to make progress. It is not testable in its own right but the idea is that it should guide thinking towards new ideas that would be testable. The route from foundational thinking to experimental checking is very long these days and will take many steps and many years. To complain that each step cannot be empirically tested or refuted misses the point of how science is being done. Note that my essay does not use the word multiverse which has been used to describe too many different things.

The other thing that philosophical thinking does is to provide an interpretation of physical theories. I think that is important too if we want to understand where we fit in the grand scheme of things, rather than merely finding practical uses for science.

Dear Philip,

You wrote:

"Thus we learn finally that there is no mysterious force that defines our consciousness.

We have no existence beyond our journey in this material world."

However, No extra mysterious force is needed to understand local or universal entanglement between mirror symmetric particles at large distances right?

So if the universe has mirror symmetry, from the start, then we live in one of the two ( or even more) instant entangled symmetric universes.

Then Max Tegmark is right if he suggest that there is a copy person over there who also read these letters ! at the same moment.

See: Democratic Free Will in the Instant Entangled Multiverse.

    Hi leo, good to see you here. Are you doing an essay this year?

    Dear Sir,

    Dimension is the perception of differentiation between the internal structural space and external relational space of objects. Since we perceive through electromagnetic interaction, where the electric and magnetic fields are perpendicular to each other and both move perpendicularly, we have three mutually perpendicular dimensions. These are invariant under mutual transformation (if we treat length as breadth or height, the object is not affected) and can be resolved into 10 different combinations. But even after more than a century of failures to find extra-large or compact dimensions; you still subscribe to such fiction perpetuated by the novel FLAT LANDS!

    There are many unexplained questions relating to the strings. For example, given the measurement problem of quantum mechanics, what happens when a string is measured? Does the uncertainty principle apply to the whole string? Or does it apply only to some section of the string being measured? Does string theory modify the uncertainty principle? If we measure its position, do we get only the average position of the string? If the position of a string is measured with arbitrarily high accuracy, what happens to the momentum of the string? Does the momentum become undefined as opposed to simply unknown? What about the location of an end-point? If the measurement returns an end-point, then which end-point? Does the measurement return the position of some point along the string? (The string is said to be a Two dimensional object extended in space. Hence its position cannot be described by a finite set of numbers and thus, cannot be described by a finite set of measurements.) How do the Bell's inequalities apply to string theory? We must get answers to these questions first before we probe more and spend (waste!) more money in such research.

    We have discussed Wigner's paper in our essay "REASONABLE EFFECTIVENESS OF MATHEMATICS" to point out the fallacy. In conformity with the second law of thermodynamics, arrow of time is well established - Past, Present and future are segments of sequences of intervals between events that are strictly ordered - all of future always follows present. The same sequence is not true for past, because any past event can be linked to the present bypassing the specific sequence of its occurrence but you cannot move from past to future violating the sequence. Further, we can remember events of the past and not of future. Thus positrons travelling backwards in time, is fiction. True, time and space are emergent properties, but not because of M theory or LQG. There are simpler explanations based on empirical principles that explain these.

    Obviously, this new way of thinking is "giving up" on fundamental physics!

      Hi Philip,

      Sorry I was not able to cope with the subject.

      Perhaps an other time or perhaps ablog post

      However indeed the relation between Math and physics for me is sort of a problem.

      Pehaps you remember that Gerard 't Hooft my topological string model declined because my model did not fit into known math sustems.

      I believe that OUR COMPLEX WORLD can not be described by FORMULAS ALONE. WHY? Because we don't know why the universe is as it is. An example: "Finetuning": Why are the "fundamental constants" constant? My suggestion: because the sub-quantum FORM of particles and the Higgs vacuum lattice have a certain form and play a game with us.. So I designed simple convertible shapes for real QUANTUM particle information use. At the same time I realized that black holes should also have some nuclear form and as a result I found that dark matter is related to black holes and Higgs particles have only energetic mass inside an oscillating Higgs vacuum lattice. Multiverse based mirror symmetric consciousness (entanglement) is assumed to be the base for all particle- wave -and human guidance or wavefunction collapse. SEE: https://www.flickr.com/photos/93308747@N05/?details=1and: http://vixra.org/author/leo_vuyk

      I am an architect who is interested in the possible sub-quantum particle FORM as information medium and building blocks in nature. I also focus on the possible dynamical FORM transformation aspects in micro- and macro physics as a base for dark matter black holes, the Higgs field vacuum and the Big bang. see also:Attachment #1: STEPHEN_HAWKING_1.jpgAttachment #2: YELLOW_BALLS_2.jpg

      Dear Pilip,

      I like your statement: "layers of speculations" are needed etc. because I also think that this out of the box thinking could be productive.

      IMHO:

      I think that Stephen Hawking did not calculate with the possibility of a chiral oscillating Higgs field vacuum lattice combined with propeller shaped Fermions. Then, Electrons and positrons could both pushed away from the BH horizon at different distances, forming two charged separated spheres. With quark ( plasma) formation in between So Black Holes could be charge splitters violating the 2e law. Combined with a continuous microscopic big bang plasma creation process!

      The result I try to describe :

      1: Dark Matter is the same as Black Holes, they all consume photons and even gravitons but REPEL Fermions due to their propeller shape.

      2: Dark Energy is the oscillating ( Casimir) energy of the Higgs Field equipped with a tetrahedron lattice structure.

      3: Quantum Gravity = Dual Push= Attraction (Higgs-Casimir opposing Graviton push).

      4: The Big Bang is a Splitting Big Bang Black Hole (BBBH), splitting into smaller primordial Splinters and evaporating into a zero mass Higgs particle based Higgs field.

      5: So Primordial Big Bang Black Hole splinters (PBBS) evaporate partly into the energetic oscillating Dark Energy Higgs field.

      6: Dual PBBSs hotspots, produce central plasma concentration in electric Herbig Haro systems as a base for stars in open star clusters as a start for Spiral Galaxies or later in Super Nova Nebula as a start for a planetary star system.

      7: Spiral Galaxies will keep both Primordial Dark Matter Black Holes as Galaxy Anchor Black Holes (GABHs) at long distance.

      8: After Galaxy Merging these GABHs are the origin of

      Galaxy- and Magnetic field complexity and dwarf galaxies .

      9: Dual Black Hole systems produce Plasma direct out of the

      Higgs field because two Higgs particles are convertible into symmetric electron and positron (or even dual quark-) propellers (by BH horizon fluctuations).

      10: The chirality of the (spiralling) vacuum lattice is the origin our material universe. (propeller shaped positrons merge preferentially first with gluons to form (u) Quarks.

      11: The first Supernovas produce medium sized Black Holes as the base for secondary Herbig Haro systems.

      12: last but not least ALL Dark Matter Black Holes are supposed to be CHARGE SEPARATORS with internal positive charge and an external globular shell of negative charged Ions and electrons.

      Thank you for an interesting essay, Philip Gibbs

      I agree strongly with the position you take on universality being the common bond between mathematics and physics. I do wonder if a universal property is that everything is unique, if we get precise enough in our measurements.

      And I am responding to this sub-thread regarding foundations of mathematics mentioned by Prof. Crowell. We might need to consider the assumptions in the foundations of mathematics- especially as mathematics is applied to physics. In particular we assume our system of representing quantities (numeric representations) are adequate for what we can measure. What about things we might be unable to measure (today)? While we might be able to accomplish much of technology today using Rational numbers (we can only approximate Real numbers), we would be completely unable to build our technology with only fractions - a representational system for Rationals. The calculational power of decimals (and like based systems) far outstrips that of fractions. Might there be a more powerful system than the single-based numeric systems we use today that could manage calculations unthinkable today? Such a system would likely apply to a larger set of numbers and encompass operations not in our current systems (more universal). Being on the boundary of theoretic and applied mathematics, it could have a major impact on science as well.

      I am not sure if comments are working here. I had two notifications of comments but nothing has appeared.

      Excellent paper Phil,

      I like the way you would re-frame our treatment of the vacuum, and I agree that a multiplicity or landscape of vacuum state solutions is a feature of a large class of quantum gravity candidate theories, not only Strings. I like the way you informed us about how the concept of an algebra can be generalized, and about the free Lie algebra - which is new to me, but obviously significant. Also; I like that you weave in higher category theory, as I savvy that the category theoretic framework can subsume a lot of other Maths.

      Well done!

      Jonathan

        Thanks Jonathan and good to see you in the contest again. I will be looking at your essay soon.

        Phil

        Dear Philip,

        In Grothendieck's 'dessins d'enfants' all is about a two-generator free group, as I am rediscovering step by step with Magma, motivated by the application to quantum observables and contextuality. Reading your wide range excellent essay, I start to be convinced that playing with free algebra over the appropriate rings, new territories of understanding may be reached.

        As you refer to topics also investigated in my essay, e.g. Moonshine, modularity and groups, I suspect you may be interested to read me. I would love to have some comments from your side.

        Best,

        Michel

          Michel, thanks for your feedback. I am glad to see you back here. Your areas of maths are very closely linked to my ideas although I do not knoe them as well as you do. If my talk of free algebras gels with your thinking then I am encouraged by that.

          I will of course be reading your essay shortly

          Dear Philip Gibbs,

          "You talked about nature of physical laws and mathematical structures and then metaphysical structures to guide us in the development of physical theories. why we exist and why laws of physics are so steeped in mathematical abstraction.Uncovering the meta-laws is now the most important goal in our quest to understand the universe.

          You also talked about referring Wigner that We don't know why complex numbers originally formulated in analysis and algebra became so useful in number theory and physics?

          The deepest questions we can ask about existence are "How do we exist?" and "Why are things as they are?"The Mathematical Universe Hypotheses tells us that all logical possibilities are equal. It does not require a magic spell to bring one chosen system of equations into reality.

          We will discover more about the relationships between algebra and geometry that determine the emergence of space and time in a universe governed by the laws of energy and entropy that are needed for life to evolve."

          Let me quote Swami Vivekananda who had addressed World's Parliament of Religion held at Chicago in 1893. Swamiji was a man of higher consciousness.The great scientist Nicholas Tesla and many others were deeply influenced by him and used to take guidance from him by attending his lectures. He hinted at scientific theories decade before Albert Einstein formulated his relativity theories.

          So, what did Swamiji say?

          He made statements like, "Take

          anything before you, the most material

          thing--take one of the most material

          sciences, as chemistry or physics, astronomy

          or biology--study it, push the study forward

          and forward, and the gross forms will begin

          to melt and become finer and finer, until

          they come to a point where you are bound to

          make a tremendous leap from these material

          things into the immaterial. The gross melts

          into the fine, physics into metaphysics, in

          every department of knowledge."[Please refer to the attached file for his detailed view on Cosmology,Universe,Matter,Existence.

          Before asking the question why do I exist, one needs to be able to answer Who am 'I' and what is 'I' ? paradox of Self-Consciousness Albert Einstein rightly put(please refer to my essay for his quote) that the separation of human from the Universe as different entity is optical delusion and deep lack of consciousness. MUH,ERH claiming about "physical laws independent of human" & mathematical structures should explore what is human or say 'I'(for that human) ? Who creates mathematical structures used as language for physical reality because every language has certain structures behind its existence. If it asks the existence of mathematical equations,but what governs the physics of equation itself ? If Wigner said that complex number is advanced concept ? Complex numbers have been so useful in number theory to Quantum physics? Why so effective? Eugen Merzbacher in his QM book took the most general structure of wave and showed that in order to satisfy the condition that physical characteristics of the wave should remain invariant under the displacement in space-time directions, the parameter comes out to be'i'(complex number. Here is the laws of invariance behind complex number that makes it so useful . Why we defined (-)*(-)=(); why not ()*()=(-) also? It is this laws of invariance behind the mathematical structures, which makes it compatible in different physical and mathematical scenarios.

          In context of Skolem's paradox - "A particular model fails to accurately capture every feature of the reality of which it is a model. A mathematical model of a physical theory, for instance, may contain only real numbers and sets of real numbers, even though the theory itself concerns, say, subatomic particles and regions of space-time. Similarly, a tabletop model of the solar system will get some things right about the solar system while getting other things quite wrong. So, for instance, it may get the relative sizes of the planets right while getting their absolute sizes (or even their proportional sizes) wrong"

          Why so? Its not mathematics describing physics rather the laws of invariance behind mathematical structures(whether discovered /invented) describes the laws of invariance behind physical reality.

          Mathematical Structure Hypothesis(which I have propounded) states that they both having no independent existence because they both originate from Vibration. So,its not that laws of energy and entropy governs only physics but also the mathematical abstractness,which can be seen in context of Poincare & Geometrization conjecture.

          Anyway, you have written a great essay.

          Regards,

          Pankaj ManiAttachment #1: vivekanada_universe.pdf

          Dear Pankaj Mani, thank you for your detailed analysis.

          I agree that the question about conciousness is very relevant to this topic. There is a lot to say about it and I could not possibly have fitted the subject into the space for this essay. What I hope is that a future essay topic will ask that question so that I can write about it at length. Meanwhile I am always glad to see other people bringing it up.

          regards

          Phil

          Hi Philip,

          Last essay contest I had a system that created QM from just pure random numbers" reality is a mathematical structure". This year's essay has much more astonishing results and I have put in the links (at the end of the sections) to the JavaScripts program, which I am sure you have no problem with. Although I know you are a busy man.

          Philip, I am relying on you since I don't seem to have too many customers here. It is ironic that often people say "show me the math" and cut the word salad, and now when I show it, they don't want to bother and it seems like they are saying "bring on the word salad"!

          Essay

          Thanks and good luck.

          Dear Philip,

          Your statement, 'SUSY is a natural consequence of string theory and would account for fine-tuning of the Higgs mechanism', indicates the imperativeness for the string theory to be modified. Thus we may think of another set of principles with strings, in that, field with matter is ascribed as single unit of eigen-rotational string-segment. Thus the Univacuum and the Multiplicity of the vacuum, that are descriptive with Space time foam and Spin-foams by String Vaccuua, is differently interpreted with an alternative paradigm of Universe; that is used for a comparative analysis in my essay, ' Before the Primordial Geometric origin: The Mysterious connection between Physics and Mathematics'. Hope you may enjoy in reading that.

          With best wishes,

          Jayakar

          Dear Philip,

          Thank you for your essay, excellent as always, stimulating reflection. But it is not about praising. Let us start a discussion.

          I do not agree with your interpretation of Tegmark's Mathematical Universe Hypothesis... You argue that "such ideas are about concepts beyond our ordinary experience for which we do not have predefined words. To think about them we can only use metaphors with meaning that we understand within our own limits." Really the MUH is about to find the mathematical structure (or structures) isomorphic to the world we observe (the empirical domain) and finding a description (language) expressible in a form that is well-defined also according to non-human sentient entities (say aliens or future supercomputers) that lack the common understanding of concepts that we humans have evolved. In MUH not all mathematical structures exist as physical reality. Only these that we can embrace with our empirical domain.

          If we want to know the geometrical structures describing the observed reality we cannot invent them. We can only discover what geometries are possible in 3+1 dimensional spacetime. With helping hand of Perelman, that proved the geometrization conjecture in 2003, we know for sure all geometries that are possible in this case. Starting from the conjecture we do not need more than these (complicated enough) structures to describe all observed reality. So I conclude that dimensions higher than observed 3+1 are INVENTED not DISCOVERED.

          I argue that we can find "connections between subjects that had previously seemed unrelated". I mean Thurston geometries in connection with matter and fundamental interactions. So I have coined the related name: Geometrical Universe Hypothesis. Thanks to the correspondence rule, that is a real paradigm shift, the geometrization conjecture becomes the first theorem in physics. Moreover it promises universality. There is naturally a metric associated with each Thurston geometry. Let us remember that Perelman proved the geometrization conjecture using Ricci flow with surgery. The constant curvature geometries (S3, H3, E3) arise as steady states of the Ricci flow, the other five geometries arise naturally where the dynamics of the Ricci flow is more complicated and where topological changes (like neck pinching or surgery) happen. Thurston geometries with Ricci flow and surgery make the spacetime devoid of singularities and we naturally get the symmetries.

          Do we need new data or new experiments to find details of GUH? Only to confirm its predictive power concerning that five more exotic geometrical structures that remain to be uncovered in nature.

          Maybe GUH is too good to be true? Or maybe it seems too simple to be acceptable (simple if one can comprehend the Perelman's proof!)? In details this is really complicated and at the moment it is only an sketch. The examples of that complexity you can find in Torsten Asselmayer-Maluga's publications e.g. "How to include fermions into General relativity by exotic smoothness" http://arxiv.org/abs/1502.02087

          There are also publications on how the Ricci flow can pass through singularities and continue on a new manifold! E.g. The Kahler-Ricci flow through singularities, Jian Song, Gang Tian, http://arxiv.org/abs/0909.4898v1

          The final question: Is there any possibility to get an experimental confirmation of the statement that space and time are emergent? You confirmed that no one knows from what and Matrix-theory, the amplituhedron and LQG are purely theoretical works.

          If you are interested you can find details of GUH in my essay.

          Sorry for my excessive self-confidence. I would really appreciate your criticism. Thank you.

          Jacek

            Hello Philip

            I was able to read your essay despite the fact that most of the concepts you deal with either in physics or mathematics were too technical or specialized for me to understand the points you are making. Is it possible to describe what you mean by universality in a simple way or by analogy?

            Nevertheless the essay is lucid and well-written and I read it through. It left me with the hope or rather belief that beyond all the disparate phenomena and complicated theories there is a breathtakingly simple unity.

            That is what I have argued in this year's essay, and this time did not have the aid of the elephant as I too did in a past essay, but of the amazingly 'smart' slime mold that can solve mazes. Amazing world!

            Best wishes

            Vladimir

              Vladimir, these issues are technically difficult for everybody and we can only move forward by pulling together and throwing in good ideas. I am glad to see you back to do that again. I too find the subjects difficult so I pick out the bits I understand and try to see some of the picture take shape from those.

              Thanks for your comments, I will probably be nicking your slime mould idea next time.
