Essay Abstract

Impressive progress in physics has clearly established that the cosmic space is a vibrant field. It sustains everything as its energetic oscillations - all the observable EM waves, particles and other diverse fluctuations. Larger and larger assemblies of the stable particles give rise to the atoms, the molecules and eventually the larger bodies of planets, stars and the galaxies. Everything is embedded within this sea of fluctuations. No interactions, leading to newer measurable and observable outcomes, are free of influence from this stochastic background. So, our experience of the three UN-’s of this essay competition is natural. Yet, our knowledge of the working rules behind the evolving universe has been advancing remarkably well through several centuries. However, for last fifty years or so, the progress in physics appears to be slow. This essay presents an epistemology of successfully and synergistically using the set of tools available to us to keep getting closer and closer to the ontological reality, even though all the individual tools, separately, are quite limited. We can make the three UN-’s keep yielding to our progress without the need to be eliminated. Dissection of our scientific tool appears to be as follows. (i) The Mental Tool is dominantly used to generate the founding axioms/postulates to integrate a broad class of observed natural phenomena. (ii) The Measurement Tool is used to quantify our observations. (iii) The Math Tool, is used to construct mathematical theories utilizing the axioms as guidance. We are proposing an extension of the mental tools to incorporate our old tradition of visualizing the invisible interaction processes. Judicious and iterative use of all these four tools will assure our steady progress towards actual realities of the universe. Unlike Copenhagen Interpretation, we do not need to give up visualizing ontological reality.

Respected Professor Chandrasekhar Roychoudhuri,

Namaskar sir!

It is very pleasant to meet you again in this FQXi forum!! We did lots of correspondence 2 years back.

I hope you remembered the Chaya Someswara Alayam near Hyderabad, where a shadow of a pillar comes on the temple sanctum cantorium (Garbha Gudi) constantly at one place , irrespective of SUN position in the sky. The shadow is constantly there from morning 6 to evening 6 on all sunny days at the same place!!! That was the science of the Indian engineers about 1000 years back.

You are a professor of Physics of Light, and now you wrote this wonderful essay!!!

I am just quoting your wonderful closing words................Complexity theory tells us that. We should not try to tell nature how she ought to behave simply based upon our powerful and sophisticated mathematical logics. More we study nature more the cosmic evolution appears to be a magnificent creative system engineer.............

In my essay " A properly deciding, Computing and Predicting new theory’s Philosophy " , also I just mentioned similar words about mathematics. One should not blindly search for mathematical problems in nature.

Hope you will be able to spend little time there....

Best Regards

Thank you "snp" for reading my essay. Hope you have grded it. I will soon read your essay and grade it.

Thank you also for contacting me through "FQXi" about the "localized shadow of a pillar through out any sunnay day". If the solution is known to common people, send me a description, and the relevant web-address. If the solution is not available on the web, I will spend some time to figure out the scientific solution. Of course, I cannot assure that I will succeed in finding the solution; hoewever, I will try.

Since this topic of "Shadow" is beyond this essay competition, contact me through:

Dear Professsor Roychoudhuri

I thought your paper was marvelous. I will have to reread it to get your perspectives on many ideas including the method to use math constructively in my ‘Universe is Otherwise” paper. It has no fixed constants. The term stochastic that you use is a great analogy for me.

Regarding space, some use aether, but you improve that with the cosmic space - a vibrant field. It sustains everything as its energetic oscillations - all the observable EM waves, particles and other. That could include my nature of space being EM radiation throughout.

The wave particle duality is regularly an issue in cosmology. ‘ Just as Newton and Huygens believed that their wave-particle debate reflected their ignorance about the deeper nature of light,’ you believe that we are still suffering from the ignorance about the real physical origin of particle-particle superposition effect. My system suggests that all that moves are equal. Physics got into the duality problem by isolating waves from particles. But we should see all are subject to gravity. Waves can be the nature of space and give it the ability to flow.



As you say, for last fifty years or so, the progress in physics appears to be slow. Inflexibility keeps our a significant overhaul.

Can your great knowledge base merge in well with my perspective?

I wish you the very best,

Paul Schroeder

Hi Chandra!

Wonderful essay! I really love your point, that an observer's limited knowledge has a very real physical effect. And, I love your view of measurement. I read somewhere that a measurement is a "copy" function of some data into an apparatus, but I actually disagree with that notion. Instead, it is a reduction function, or a coarse-graining of some data with the context of an observer in mind. What are your thoughts on this?

Cheers!

Alyssa

Hi Alyssa: It is not quite the same, perhaps, but Descartes’ philosophy of reductionism, somehow can lead to your suggestion of “modularize” complex problems into small segments [ https://en.wikipedia.org/wiki/Reductionism ].

Being an experimental physicist, I have dissected the essential steps behind data gathering in all of our experimental apparatuses. In the process, I have found...

Dear Schroeder:

Thank you for making positive comments on my essay.

Yes, some of your ideas does match my mode of thinking. I have given fi=urther refrences below. These should help you decide exactly where our mode of thinking are synergistic, and collaboration would be fruitful.



You say that:

“The US remains locked in to the ‘Standard Model’. Meanwhile, in other countries the science world is opening windows for alternate logic.”

No question about the first sentence. Give me name and connections related your second sentence. We can build newer platform and strengthen it slowly, but, steadily.

“Somehow the Doppler idea had captured minds and has hidden gravity.”

Again, agree to some extent. Feel free to down load my “Doppler” paper from the following link:

http://www.natureoflight.org/CP/

Request the paper identified as “2013.5”. You may like it.

“Since space is the content of the universe, thus the universe is infinite. It is properly defined as being everything.”

Download my paper on space as a Complex Tension Field” (CTF). This is a much more advanced concept than old ether.

“Next Frontier in Physics—Space as a Complex Tension Field”; Journal of Modern Physics, 2012, 3, 1357-1368,

http://dx.doi.org/10.4236/However, mp.2012.310173

“Actually, light flow slows and becomes lower frequency microwaves etc. due to gravity. Gravitational red-shifting of light is everywhere.”

Does this really explain Cosmological Redshift? Could you kindly give me some references? I am not expert in this field.

Sincerely,

Chandra.

Hi Chandra, Good to compare again our entirely consistent coherent approach to understanding nature. Great shame you got to busy for our intended collaboration after last year, I can see areas where the 'sum of the parts' may bring massive progress! Indeed I have made some, a key paper on the 'measurement problem' mechanism I know you'll like is in peer review with Nature now.

I'd like to suggest answers to some of your open questions; There IS a near instantaneous modulation of polarisation state ('the wave function') on a 'scattering' re-emission, physically derivable. Would that shock?

Then; there is NO SINGLE 'stationary cosmic field', but there is always a LOCAL BACKGROUND rest frame, which then has it's own, repeatedly. Einstein actually got this in 1952! but was ignored then died.

Lastly; I give you a passing bus. Light at c in your frame enters it's front screen, propagates at local c WITHIN the bus, then exits the rear screen reverting to it's old local c. NOW visualise how wavelength and f change!! And to WHO!!! Remember YOU can't directly measure it while it's in the bus. I'm in the bus. I find c and reduced wavelength on interaction. 'Frequency' is JUST a 'time derivative'!!!

All falls into place once we use the correct keys. But I can't do this alone. I hope you might perceive some veracity again but have time to help. Times almost up so I hope you get to mine.

Well done for yours, Important message well argued, and right direction for sure if not yet quite on those tracks!

Very best.

Peter

Peter:

Many thanks for your quick response.

I am soprry that I forgot to follow up last year to define some collaborative work with you.



Remeber I am an experimentalist with a lot of hands-on background in classical optics. If you want, I could send you a copy of my 2014 book on optics. Let me know.

Since I have your email, I will send you another of my recent paper where I am starting to connect optics with modern physics. This paper may help you define soem problem thta we can collaborate.

Right now, I am collaborating with several physicsts to define "photon" and model photo-electric-current-pulse statustics with "photons" as classical pulses. This model directly contradicts the current assumption of "bullet photon". Could this thinking make any connection with your thinking?

Thanks,

Chandra.

Chandra, I'd love a copy of your book, thanks, email pj.ukc.edu@physics.org I'd like to see the hypothesis of electron re-emission at c with respect to electron centre of mass frame irrefutably demonstrated. It's consistent with all experimentation I'm aware of, but not recognised as an interaction effect, or it's important implications recognised. (In a diffuse 'gas' we then find birefringence subject to extinction distance, as as J.D Jackson).

Can I assume you're familiar with 'Kinetic Reverse Refraction'?

Very best

Dear Chandra,

I greatly appreciated your work and discussion. I am very glad that you are not thinking in abstract patterns.

"Impressive progress in physics has clearly established that the cosmic space is a vibrant field. It sustains everything as its energetic oscillations - all the observable EM waves, particles and other diverse fluctuations. Larger and larger assemblies of the stable particles give rise to the atoms, the molecules and eventually the larger bodies of planets, stars and the galaxies. Everything is embedded within this sea of fluctuations. No interactions, leading to newer measurable and observable outcomes, are free of influence from this stochastic background".

"Unlike Copenhagen Interpretation, we do not need to give up visualizing ontological reality".

While the discussion lasted, I wrote an article: “Practical guidance on calculating resonant frequencies at four levels of diagnosis and inactivation of COVID-19 coronavirus”, due to the high relevance of this topic. The work is based on the practical solution of problems in quantum mechanics, presented in the essay FQXi 2019-2020 “Universal quantum laws of the universe to solve the problems of unsolvability, computability and unpredictability”.

I hope that my modest results of work will provide you with information for thought.

Warm Regards, `

Vladimir
