Dear Peter,

Thanks for your kind remarks. I hope you may also bear with me if I suggest that we require a theory which can answer why the world is there and why we are here! Then your proposal, or any theory of quantum gravity, would become "incomplete and flawed" in your terms!

I have kept limited myself, in the present essay, to only the most successful theory of gravitation, i.e., GR. However, there are hopes, in the proposed framework, for further developments, on which I'm working. You know that one of the most common ways for a particular theory to be renormalizable is to be scale invariant. And equation R^{ik}=0 (on which the proposed paradigm is based) presents an scale-invariant theory!

Best Regards.

Ram,

I quite agree your model may be only 'slightly', but mine may be entirely 'flawed', and almost certainly is: "All we know will ultimately be revealed as false." The best answer I found to why we may be here is Richard Nixeys, we are an organic experiment, which may be called a 'computer' to find out why the scale-invariant greater universe exists! Yes, I agree scale invariance is essential. But I think there are questions we CAN answer which we yet have not.

I think that is the reason we postulate theories, to be falsified, and that is the reason I would like you to read my essay; so you can judge for yourself. I confirm I was very impressed by your work and believe I will greatly respect your views.

Very best wishes and thank you.

Peter

Having read so many insightful essays, I am probably not the only one to find that my views have crystallized, and that I can now move forward with growing confidence. I cannot exactly say who in the course of the competition was most inspiring - probably it was the continuous back and forth between so many of us. In this case, we should all be grateful to each other.

If I may, I'd like to express some of my newer conclusions - by themselves, so to speak, and independently of the logic that justifies them; the logic is, of course, outlined in my essay.

I now see the Cosmos as founded upon positive-negative charges: It is a binary structure and process that acquires its most elemental dimensional definition with the appearance of Hydrogen - one proton, one electron.

There is no other interaction so fundamental and all-pervasive as this binary phenomenon: Its continuance produces our elements - which are the array of all possible inorganic variants.

Once there exists a great enough correlation between protons and electrons - that is, once there are a great many Hydrogen atoms, and a great many other types of atoms as well - the continuing Cosmic binary process arranges them all into a new platform: Life.

This phenomenon is quite simply inherent to a Cosmos that has reached a certain volume of particles; and like the Cosmos from which it evolves, life behaves as a binary process.

Life therefore evolves not only by the chance events of natural selection, but also by the chance interactions of its underlying binary elements.

This means that ultimately, DNA behaves as does the atom - each is a particle defined by, and interacting within, its distinct Vortex - or 'platform'.

However, as the cosmic system expands, simple sensory activity is transformed into a third platform, one that is correlated with the Organic and Inorganic phenomena already in existence: This is the Sensory-Cognitive platform.

Most significantly, the development of Sensory-Cognition into a distinct platform, or Vortex, is the event that is responsible for creating (on Earth) the Human Species - in whom the mind has acquired the dexterity to focus upon itself.

Humans affect, and are affected by, the binary field of Sensory-Cognition: We can ask specific questions and enunciate specific answers - and we can also step back and contextualize our conclusions: That is to say, we can move beyond the specific, and create what might be termed 'Unified Binary Fields' - in the same way that the forces acting upon the Cosmos, and holding the whole structure together, simultaneously act upon its individual particles, giving them their motion and structure.

The mind mimics the Cosmos - or more exactly, it is correlated with it.

Thus, it transpires that the role of chance decreases with evolution, because this dual activity (by which we 'particularize' binary elements, while also unifying them into fields) clearly increases our control over the foundational binary process itself.

This in turn signifies that we are evolving, as life in general has always done, towards a new interaction with the Cosmos.

Clearly, the Cosmos is participatory to a far greater degree than Wheeler imagined - with the evolution of the observer continuously re-defining the system.

You might recall the logic by which these conclusions were originally reached in my essay, and the more detailed structure that I also outline there. These elements still hold; the details stated here simply put the paradigm into a sharper focus, I believe.

With many thanks and best wishes,

John

Hi Ram,

Thank you for a very intriguing model of gravity. You wrote:

> It would be interesting to note that a homogeneous, isotropic cosmological solution of equations (2) becomes Minkowskian.

In my essay Sofware Cosmos, I describe a computational model for the cosmos that answers many cosmological puzzles. One important distinction in my model is between the "explicate" order (which is Minkowskian) and the "implicate" order which is conformally compactified Minkowski space.

My hypothesis is that it is the curvature of the implicate (rather than total energy) that is responsible for the observed departures of gravitational force from the Newtonian. This can be calculated (via Gauge Theory Gravity) in a flat background and does not require the presence of matter. My picture also includes scale-invariance in the form of fractal structure.

I hope you get a chance to take a look and tell me what you think.

Dear Vishwakarma,

I have a question about the statement that equates K/r with gravitational energy of the field - In Newtonian physics it is not the energy of the field but the energy of a unit mass particle interacting with another particle of mass M, or the potential energy of the unit mass particle. Why and how are you equating it to the energy of the gravitational field?

Also, apart from the beginning sentence in the abstract I did not find much connection with the topic of the FQXi discussion - can you please say how you address that issue?

Thanks and regards,

Unnikrishnan

    Dear Unnikrishnan,

    Thanks for your interest in my essay. I am a bit puzzled by your first question, that why you ask such a trivial one. Is it not the potential energy of the unit mass (situated at a certain point in the gravitational field of mass M) by which we measure the gravitational (potential) energy of the field produced by mass M in the Newtonian mechanics? Is this energy not calculated in terms of the work done in bringing this (unit) mass from infinity to that point? And does this work not equal to -GM/r, where r is the radial distance between the source mass M and the unit test mass?

    The aim of the present FQXi contest is to provide foundational, innovative and influential thinking on Wheeler's dictum "it from bit". Here `bit' stands for the information and `it' for physics of the Universe. In the introduction of the essay, I have framed a goal to show that a correct physical theory of the Universe (`it') can emerge from the `bit' if perceived correctly. The rest of the essay is devoted to this goal only, in the spirit of the philosophy of the FQXi, and I did not find it necessary to mention the words `it', `bit', `information' several times unnecessarily.

    Regards.

    Posted at my essay comment area:

    Dear Ram,

    sorry for the long gap in answering your question (I was on vacation with my family).

    According to my ideas, matter is also part of the spacetime (a part of the 3-space). So verything is unified: spacetime and matter, Bit and It.

    Best

    Torsten

    Now more:

    I like your essay. You also went along the usual way not modifying the spacetime (to be discrete etc.) I rated it a longer time ago very high.

    So Good luck and Best wishes

    Torsten

    Ram,

    I do hope you may get the time to also read my essay and comment. Both having read each others seems an essential requisite for useful communication.

    You also may be able to guide me on the areas I see commonality with my more geometric, epistemic and and heuristic ontology.

    I think your work is valuable and hope my score may help it make the final cut.

    Very best wishes

    Peter

    Best of Luck for the Magnificent Eight !

    I am throught the 180 essays, all rated. For me 2/3 of them were poor and other 1/6 curious. The rest (1/6) have I rated over 4/10.

    You are among the authors of the top essays from my sight - alphabetically :

    Corda, D'Ariano, Maguire, Rogozhin, Singleton, Sreenath, Vaid, Vishwakarma,

    and I hope one of you will be the winner. (Please, don't rate my essay.)
