John,

In my essay I distinguished between two quite different notions of infinity.

I am not sure what you meant with not really.

Eckard

Eckard,

I wasn't trying to explain reality, as in first cause, or fundamental theory, so much as give a conceptual foundation for physical reality. To resurrect space as what geometry maps, not an artifact of geometry.

There are lots of potential infinities, as any open set can potentially go on forever. I'm arguing against the idea of a finite universe. I think when the James Webb space Telescope becomes operational, they will find ever more and larger structures, at ever further distances, than can conceivably be fit in the age limits of current cosmology.

I suspect the background radiation will come to be seen as the solution to Olber's paradox. The light of ever further sources, shifted off the visible spectrum.

Hi John Brodix Merryman

It is important observation "It is also interesting to note that in the few days since I posted this, the issue of different methods of measuring the Hubble Constant keep yielding different numbers, with the errors bars on both just getting smaller, not converging" dear John Brodix Merryman......

............. very nice idea.... I highly appreciate your essay and hope for reciprocity ....You may please spend some of the valuable time on some of the concepts of Dynamic Universe Model also and give your some of the valuable & esteemed guidance

Some of the Main foundational points of Dynamic Universe Model :

-No Isotropy

-No Homogeneity

-No Space-time continuum

-Non-uniform density of matter, universe is lumpy

-No singularities

-No collisions between bodies

-No blackholes

-No warm holes

-No Bigbang

-No repulsion between distant Galaxies

-Non-empty Universe

-No imaginary or negative time axis

-No imaginary X, Y, Z axes

-No differential and Integral Equations mathematically

-No General Relativity and Model does not reduce to GR on any condition

-No Creation of matter like Bigbang or steady-state models

-No many mini Bigbangs

-No Missing Mass / Dark matter

-No Dark energy

-No Bigbang generated CMB detected

-No Multi-verses

Here:

-Accelerating Expanding universe with 33% Blue shifted Galaxies

-Newton's Gravitation law works everywhere in the same way

-All bodies dynamically moving

-All bodies move in dynamic Equilibrium

-Closed universe model no light or bodies will go away from universe

-Single Universe no baby universes

-Time is linear as observed on earth, moving forward only

-Independent x,y,z coordinate axes and Time axis no interdependencies between axes..

-UGF (Universal Gravitational Force) calculated on every point-mass

-Tensors (Linear) used for giving UNIQUE solutions for each time step

-Uses everyday physics as achievable by engineering

-21000 linear equations are used in an Excel sheet

-Computerized calculations uses 16 decimal digit accuracy

-Data mining and data warehousing techniques are used for data extraction from large amounts of data.

- Many predictions of Dynamic Universe Model came true....Have a look at

http://vaksdynamicuniversemodel.blogspot.in/p/blog-page_15.html

I request you to please have a look at my essay also, and give some of your esteemed criticism for your information........

Dynamic Universe Model says that the energy in the form of electromagnetic radiation passing grazingly near any gravitating mass changes its in frequency and finally will convert into neutrinos (mass). We all know that there is no experiment or quest in this direction. Energy conversion happens from mass to energy with the famous E=mC2, the other side of this conversion was not thought off. This is a new fundamental prediction by Dynamic Universe Model, a foundational quest in the area of Astrophysics and Cosmology.

In accordance with Dynamic Universe Model frequency shift happens on both the sides of spectrum when any electromagnetic radiation passes grazingly near gravitating mass. With this new verification, we will open a new frontier that will unlock a way for formation of the basis for continual Nucleosynthesis (continuous formation of elements) in our Universe. Amount of frequency shift will depend on relative velocity difference. All the papers of author can be downloaded from "http://vaksdynamicuniversemodel.blogspot.in/ "

I request you to please post your reply in my essay also, so that I can get an intimation that you replied

    Dear John Brodix Merryman

    Thank you for reading my essay....

    You have nice concept; probably that there is a cyclical relationship between expanding radiation and collapsing mass.

    It is nice idea .... I never heard it before... this concept is good... that ' That mass is an effect of what we call gravity, rather than gravity a property of mass and this contraction extends to all stages and aspects of frequency contraction, or blueshift.'

    We should develop further, lets work out together.... By the way there is no darkmatter in Dynamic Universe Model.......

    Best Regards

    John,

    Your essay seems as compact as a neutron star since light does escape in the form of word packets with great perspective width. Your ideas are fresh to me and thought provoking. I deal with light and space too but with more convention. Hope you can check out mine. I will need to think about yours.

    John,

    Seems to be sparse reviewing and rating in this essay contest. I am revisiting those I have reviewed and see if I have scored them before the deadline approaches. I find that I have not scored yours and am doing so today. Thanks for your Olympic-sized comments.

    John,

    Good to be in another contest with you. I too bashed out an essay on Space just in time to meet the deadline. We both agree it is fundamental.

    I could not resist going after a TOE based on a novel concept of a graviton. I go after what the curvature of space-time means. This investigation results in a malleable ether that explains: 1. the curvature of space-time and 2. why the speed of light is independent of an objects motion.

    I know this conflicts with a pure void which is aesthetically pleasing.

    This is a long shot, but do visit my essay. I like to believe it enhances the beauty of the void and you will like it.

    Thanks for your fine essay: "The vacuum might fluctuate, but first you need the vacuum.

    Dear John,

    Replied to your comment on Flavio and Chiara's 'Demolishing Prejudices' essay, however as i understand our fqxi gui you will not get pinged by that. So pasting the comment in here:

    Dear John, Flavio, Chiara,...

    love the way dialogs evolve in the fqxi competition/collaboration format.

    Came back to 'Demolishing Prejudices' to reply to a different thread and got caught by 'Do NOT spend...'. Being closely related to oppositional defiant disorders, i was immediately in.

    takedown of cosmology and inflation is excellent, thank you. That it leads to classifying redshift, accelerating expansion, anomalous radial dependence of galactic rotation,... as 'optical effects' gives a nice little perspective shift. Suggests to me that until we understand how quantum gravity is related to the photon the 'Do NOT spend...' injunction is well advised.

    staying with the optical effect for a moment, in particular to have an understanding of what goes on in the near field at the Planck length in photon emission and absorption seems essential in quantum gravity.

    I like what is said about time, that it emerges from 'action', or more precisely from inter-actions. Pauli vacuum wavefunction is that of the geometric objects of 3d space - point, line, plane, and volume elements of geometric interpretation of Clifford algebra. No time there.

    Interaction of two wavefunctions can be modeled by geometric product of Clifford algebra - sum of inner (dimension lowering) and outer (raising) products. Inter-action generates the 4D Dirac algebra of flat Minkowski spacetime. Time emerges from interactions of the enigmatic unobservable wavefunction.

    Dear John,

    Your view that 'space is basis' seems intuitively perceptive and powerful. In the language of geometric Clifford algebra (the geometric interpretation of the particle physicist's matrix representation is unfortunately lost in the mainstream), the Pauli matrices are the basis vectors of 3D Euclidian space, and the Dirac matrices those of flat 4D Minkowski spacetime.

    very much like your view on 'optical effects'. Thank you.

    Best regards,

    Pete

      Stefan (and John) - It could be that the world is deterministic at the fundamental level, say for instance at the level of the unobservable wavefunction, and becomes probabilistic only with the phenomenon of emergence.

      Peter,

      Rushing off to work so reply further later, but just mention I got into physics as a way to better understand society, given the powerful physical forces permeating it.

      Here was a FQXi entry of some years ago, addressing the social aspects of it.

      Dear John Merryman

      I have read your essay and suggest that you read Dark Matter http://vixra.org/pdf/1303.0207v3.pdf

      I also invite you to read my essay on wave-particle and electron spin at: https://fqxi.org/community/forum/topic/3145 or https://fqxi.org/data/essay-contest-files/Rajpal_1306.0141v3.pdf

      Dear John,

      Thank you for the lengthy and detailed comment you wrote on the page for my essay. I appreciate it.

      In response to your essay, I would agree with you that there has been considerable confusion between space as the void, empty of all content, and space as a vacuum, which is perhaps empty of ordinary matter but which can still be characterized in terms of various fields, vacuum energy, and so. I would further agree with you that only the former of these is simple and primitive enough to deserve to be thought of as the basis. Maybe the void is not quite nothing in a metaphysical sense, but it is closer to metaphysical nothing than a vacuum which has various properties. You are correct to point this out.

      Laurence Hitterdale

        Lawrence,

        Thank you for reading, commenting and appreciating the point that while physics is largely based on the vacuum as a field, it goes out of its way to deny that space is the basis of that field, insisting on abstract geometry.

        I wouldn't even call it the void, because to paraphrase; "Nature abhors a void." Just that no matter how filled this void is, it is an unbounded equilibrium. The zero, the flatline, around which all fluctuates.

        Dear John Brodix Merryman,

        You wrote a good essay, drawing attention to the fact that the space is fundamental. Your essay would be even better if you were familiar with the principle of identity of space and matter of Descartes. He says

        matter is space and space is matter that moves. Descartes physical space is a matter, in which there are no voids. But if they are formed, then, according to him, close instantly. However, given modern notions that the speed of light is the limit for any real movements in the New Cartesian Physics States that the voids in the space close to the speed of light. For intelligent people from this moment begins the real physics. Look at my essay, FQXi Fundamental in New Cartesian Physics by Dizhechko Boris Semyonovich

        Where I showed how radically the physics can change if it follows this principle. Evaluate it according to your fundamental concept and leave your comment there. Then I'll give you a rating. Do not allow New Cartesian Physics go away into nothingness, which can to be the theory of everything OO.

        Sincerely, Dizhechko Boris Semyonovich.

        The consciousness of the people resists the recognition of the identity of space and matter Descartes, because they used to think that I live in an empty space - it is convenient for them. While there was no reason to think otherwise. However, there will come a time when the level of education of the people will depend on their understanding of this identity. This requires the necessity to eliminate the difficulties in science. Fundamental should save our thinking, i.e. to be simple and straightforward. Physical space, which for Descartes is a matter that is the basis for fundamental theories in science.

        You might like to look at the sky and it seems to you empty infinite space in which it moves large and small body. However, this impression is deceptive. According to the principle of identity of space and matter Descartes, space is matter that moves. When Copernicus asserted that the Earth revolves around the Sun, it had, according to Descartes, to add that along with the Earth revolves around the Sun, all the solar space. Space is what built the world.

        If the believer to ask, where is God? He will answer - in the sky. When you look into infinite space and I think that is the body of God, that needs to be asked, and how it works? The answer is simple, all the changes around and our weight is the result of his actions. In space contains information about changing the world. Time is a synonym of total moving

        Sincerely, Dizhechko Boris

          Boris,

          The problem with the concept of God is it assumes a spiritual absolute would be an ideal from which we fell, when it would be an essence from which we rise. More the raw consciousness of the new born child, than the hard won wisdom of the old man. In physics terms, more the field, than the point particle. We think consciousness is an effect of thinking, but it is the other way around. Thinking is how we express consciousness. Consciousness is the medium, thought is the message.

          John ,

          The space is called a field if every point has a potential.

          The principle of identity of physical space and matter allows us to extend physics to living matter. For this we need to pay attention to the fact that matter within the body is the same as outside it. Our brain creates an image of the outside world not within themselves and in the space around themselves. This image of the outside world has an active nature, as it controls the body.

          Sincerely,

          Boris
