Dear Satyavarapu Naga Parameswara Gupta,

I've read your essay, not without difficulties, because I'm a theoretician, dealing more with quantum theory than astrophysical measurements :-)

Nevertheless, I can see from the essay and the discussion above that you seem to be allergic to any "imaginary" concepts, including imaginary numbers, which are nothing more than a convenient way to denote 90 deg rotations ( i^2 = -1 means simply that two consecutive counterclockwise 90 deg. rotations are equivalent to one 180 deg. conterclockwise rotation).

Going back to our "It from Bit" discussion, it does not mean, at least in my opinion, a creation of matter from mental experiments. It is rather about the influence that _getting_information_ (i.e. a measurement) may have on the state of an "element of reality", including it's emergence, as it is observed in various experiments involving quantum entanglement.

You wrote:" ... we study the relation between Information and reality about CMB in this paper." A question arises, what information about reality is _encoded_in_ CMB, or it is rather the information encoded in our _models_of reality ?

Another thing, which is problematic for me, is the use of Boltzmann-Stefan law in combination with "radiation in all frequencies" in your discussion. Isn't it prone to the "ultraviolet catastrophe" problem ?

One more thing, there is a mention about your Dynamic Universe Model, based on flat Cartesian coordinates in 3D space and (global?) linear time. I'm afraid that such a model is rather problematic in view of the _observed_ properties of electromagnetic radiation.

Best Regards,

-Joachim.

    Dear Joachim,

    Thank you very much for your interest in my essay and for your time spent on this essay. These are good questions. I will be putting '''''' before your words. Next will be my answers.

    '''''I've read your essay, not without difficulties, because I'm a theoretician, dealing more with quantum theory than astrophysical measurements :-)'''''''

    Thank you once again for your efforts, any general scientific back ground should be sufficient, i feel. You have more than any such backgrounds. . . !

    ''''''''Nevertheless, I can see from the essay and the discussion above that you seem to be allergic to any "imaginary" concepts, including imaginary numbers, which are nothing more than a convenient way to denote 90 deg rotations ( i^2 = -1 means simply that two consecutive counterclockwise 90 deg. rotations are equivalent to one 180 deg. conterclockwise rotation). '''''''

    I know all those concepts. But they are not real numbers. I mean to say one should use only real numbers in their equations to get real results. real results can be used in Engineering. ( You may say 'one may get imaginary numbers as answers , which depends on their equations.)

    But in Dynamic Universe Model's case in these equations we get real results with input of real values, which can be compared with real measurements. That's what I am telling here. For eg., Time axis is itself not real, and a perpendicular axis to this is what?

    This I have already mentioned in my essay. But I am asking this question 'creation of matter from mental experiments', forming basis my discussion.

    The present day Physics says there is some information encoded at the time of Bigbang about the formation of Galaxies. The mainstream claim that that this information is the starting point of formation of the Galaxies. But the actual measure star and Galaxy light of that part of sky in Microwave ranges will give the same information.

    ''''''' Another thing, which is problematic for me, is the use of Boltzmann-Stefan law in combination with "radiation in all frequencies" in your discussion. Isn't it prone to the "ultraviolet catastrophe" problem ? '''''''

    Thank you for nice question once again. See Wikipedia,

    http://en.wikipedia.org/wiki/Rayleigh%E2%80%93Jeans_law

    In 1900 Max Planck empirically obtained an expression for black-body radiation expressed in terms of wavelength in Planck's law. The Planck law does not suffer from an ultraviolet catastrophe, and agrees well with the experimental data, but its full significance (which ultimately led to quantum theory) was only appreciated several years later. Since, then in the limit of very high temperatures or long wavelengths, the term in the exponential becomes small. . . .

    Hence I feel for our ranges, there will not be any error!

    Dear Satyavarapu Naga Parameswara Gupta,

    I read your essay. To be honest a lot of things I do not agree, but not right.

    I see that we do not have the same idea about what may be the information. For me, and I hope for a lot of other information that is all that exists, all that is reality, everything is an object or phenomenon.

    And I would like to have your opinion and so to get a better view.

    best regards

      Dear SNP Gupta,

      The theme up on which your essay is based is having deep rooted meaning and you have aptly said that it is 'IT from Bit'. I am in complete agreement with you when you say that CMB radiation is fully misinterpreted in confirming the 'big-bang' hypothesis. You have also given good reasons for that and this also follows from the large scale 'isotropy' of the universe according to general relativity. Misinterpreting scientific data from satellites has plagued the current trend in science and regarding this your essay is an eye opener.

      I also like you to go through my essay and post your comments.

      Best regards and good luck in the essay contest.

        Dear Gupta,

        A nice essay full of experimental data. However, the resemblance to the theme of this contest seems to me rather obscure.

        Let me simplify the whole thing with the following simple experiment (Did I misunderstood something?):

        Let us have a box full of water. Each set of molecules within it has its own temperature according to its molecules' kinetic energy. Hence, they emit the appropriate radiation. If we set a Vakradiation detector somewhere in this box - obviously - we will detect the VAKR... radiation that appears to be uniform and emitted from any set of molecules we like. However, the cause of molecules' kinetic energy is not explained in any way by these observations.

        This is the meaning (among many others) of Big Bang (BB) theories that it tries to explain "background" energy by saying that it came from a "superhot" singularity. Nobody seriously supports the idea that CMB came straight from BB but it came to us (no mater how) as a consequence of the BB. The observed fluctuations of CMB are caused by certain stars' or galaxies' procedures but the overall CMB - by any evidence - was caused by BB.

        During last contest I posed a major worry about our conception beyond our galaxy.

        "... Milky way (our galaxy) is even more interesting as its Schwarzschild radius is approx. 3*10^25 m (mass = 2*10^42 kg) while its radius is about 5*10^20 m. ..."

        I would like your opinion on this as it is substantially related to your essay.

        Best wishes

        Dear Satyavarapu Naga Parameswara Gupta,

        I did not make a mistake : we do not have the same idea of the word « information ». For me, any object is information. The word « information » is taken here in the large and extended sens, in the physical sense of the term and not in its abstract, symbolic and limited shape.

        We define the word according to the conception which we have of the Nature and the reality. And not according to the common opinion, or its definition in a standard dictionary.

        This is how I see the word « information » and I have my reasons which are directly related to a particular concept of the Universe.

        If you design an object in your computer and you print it in three dimensions.

        The object works, as if it was made at the factory. The symbolic information that you transformed into a physical information, is this real or an invention ?

        You are free to have a different idea of the word « information », but I have another opinion.

        With all my respects.

Your analysis treats geometrical rays but the results may be affected one way or another with diffraction included.

        Thank you once again for such good question. Dish size( Diameter) can be 0.2 to 50 Metres. I don't think your limitation will be applicable here. This diffraction will cause some more averaging effect on the measurement of radiation. What do you say.

        This is not directly or indirectly related to this essay. Because these are no Blackholes in the Dynamic Universe model, Blackholes are mathematical singularities. In this essay on CMB also, we don't use the concept of Blackholes.

        SNP,

        Thanks for presenting this essay, it was quite interesting. Although perhaps a bit off topic for this particular contest, I nevertheless appreciate approaches which attempt to examine questions from experimental perspectives.

        You might be aware that others have also proposed that the CMBR could be a result of blackbody radiation from matter in the universe. That is, if you allow for some mechanism whereby light can experience redshift with distance irrespective of cosmic expansion (of which there have been some arguments) one could posit that such presents an alternative resolution, in the same manner as cosmic expansion. To show this you would need an experiment demonstrating that the redshift occurs regardless of whether cosmic expansion exists, and further that the magnitude of redshift is sufficient to the observed intensity.

        Without a more detailed review, I'm not yet certain that your particular experiment could suitably differentiate between possible redshift mechanisms and/or anisotropy mechanisms. Such a theory suggests that measured WMAP anisotropies result from non-inflationary effects, including redshift effects unrelated to cosmic expansion, of which have not yet been demonstrated as matching the measured data, at least at present, as far as I'm currently aware.

        Also, it appears that from your essay you are considering the ISM/IGM to be the major sources of aliasing when it comes to uniformity in the CMB as measured from Earth; you state that, in your estimation, large anisotropies would be measurable outside of galaxies which suggests yet another resolution mechanism.

        The suggestion of a non-expanding universe often suggests one with infinite age and thus suggests additional considerations for resolving Olber's paradox; I did not encounter these items in your essay.

        Another issue that I didn't come across in your essay is with respect to the conversion of matter to radiation in stellar sources, in that the radiation of the universe would continue to increase until thermal equilibrium were reached by cosmic plasma. Based on the CMB measurements and your essay, the expectation then would be that the universe is far from reaching equilibrium, and may in fact never reach that state (which may be reasonable). Perhaps you have addressed this in your other papers referenced, but it doesn't appear to be covered here.

        Thanks again for presenting this. Remember that experiment, not consensus, is the bedrock of the scientific method; you don't need to be mainstream to be correct, but you do need the experimental evidence.

          I know. When there is NO mathematical singularity like Bigbang or Blackhole, why such radiation will come? I checked for 100's of areas in the sky. And the measurements are matching with observations. If you have data for any particular area in the sky, we can work-out together and match and see results. You should be interested in practical experimenting, that's it.

          SNP,

          Regarding blue-shifted galaxies... Though I will check your links, the data I am familiar with suggests that nearly all galaxies are red-shifted, with the exception of very few. In essence, out of the many billions and billions of galaxies surveyed, there are less than 10,000 that have been found blue-shifted and the explanations for those blue-shifts are quite mundane, most notably that the vast majority of these are nearby and would be expected to demonstrate velocity dispersions which would readily account for the blue-shift. The trivial percentage is obviously nowhere near what we would expect from a random distribution if we were to ignore redshift; as such, I don't think you can make that particular case with the current data. To duplicate the CMB character without expansion, I think you're going to need an alternative red-shift explanation, as I noted earlier.

          Chris

          P.S. I checked the links on your site; one works, one doesn't. However, you present data suggesting ~7000 blue-shifted galaxies out of ~558,000 in the survey which is less than 1.3% with blue-shift and those mostly appear in quite nearby regions (so that is even a high bias). The only way you can get the 31% (or thereabouts) you've quoted is if all quasars were somehow considered blue-shifted galaxies, but no quasar has yet been shown as blue-shifted (at least as far as I'm aware) in terms of its systemic body (that is, the low ionization lines when not including outflow jets as isolated components). Given that, I'm not sure how you can reconcile the data. You would need to prove that all quasars are actually blue-shifted, meaning that every quasar analysis to date has been in error; you would need some very concrete evidence which could incontrovertibly refute all the existing analysis in order to do that.
