John,

It's always good to see that someone reads your essay with some interest and with keen comments. I thinks it helps to promote the kind of analysis and thinking the foundation means to foster. Thanks, for reading and for your incisive remarks.

Dear James,

A fine philosophical essay that I much enjoyed reading.

A minor typo on page 4 re weight of local group. I suppose the mass is close to 4 or 5 trillion solar masses, not 1, as this is less than the Milky Way mass.

I agree with Peter Jackson, Alan Kadin, and some others re quantum computers.I do not think they will eventuate in their current form. (Read Barry Gilbert's comments on them).

I hope you will check out my essay, on the 3 Un's as well.

All the best

    Hi James,

    I wanted to add a comment re the missing antimatter you discuss. I wrote an essay on it back in 2003 which poses a solution. Of course I have done much more work on this topic since then and I believe I can also explain what is dark matter.

    Cheers

    Dear James,

    Writing for a general science readership in a way that is interesting and informative is the most difficult part of these fqxi essays. This essay embraces the general audience in a breezy and fluid style that even has time for some wordplay. An essay about what we don't know would seem as interesting as a blank screen, but you made us think about the how's and why's of our ignorance. Good work.

    Sincerely,

    Jeff Schmitz

    Hi James:

    Thanks for reading my essay.

    Enjoyed reading your nicely written essay. What I liked most in your essay that you emphasize the roles of understanding the cosmos and human mind are crucial to unravel the mysteries of the unknowns. You well describe the historical progress science has achieved but 96% of the universe still remains undiscovered. My essay focuses on reveling this 96% hidden universe via integrating the missing physics of spontaneity or consciousness or free will in nature.

    I have given high ratings to your essay.

    Best of luck

    Hi Jim,

    This tab was already open for this morning's reading assignment. Now moved to the front or top of list.

    First off;

    My favorite DM candidate is a graviton condensate. This can exhibit axion-like behavior without requiring additional particles. Your logical synthesis is not air-tight like some I've seen in this contest. But you raise some interesting points and you make the reader think.

    Regarding machines thinking; it is happening or is inevitable. The real question is; will they have the capacity to be subtle? Are we going to create R2-D2 and C3P0, or will we one day be enslaved by Terminators - because we got it wrong? There is no time left to wonder about whether machines can think, only about how well...

    Back in my College days; I had the nickname 'Warp drive,' or just 'Warp.' Now I could give lessons in the Math prep for that. The term warp factor arises in the work of Lisa Randall, with the Randall-Sundrum model, which features an infinite 5-d space. Theories based on the octonions or Mandelbrot Set tend more to resemble the DGP gravity model. But if reality is octonionic; a translational dymaxion is possible to construct.

    All the Best,

    Jonathan

    Hi Jim -

    Your essay is a delightful, almost poetic romp through the grassy fields of theoretical physics and human psychology.

    I do take issue with your breezy dismissal of the "3Us" - as I've discussed in my essay, I see them as a feature of reality, not a bug. Something our human minds are loathe to accept (being the control freaks that we are!).

    Jim,

    Thank you for essay. I also had found that UUU problems in mathematics ( Riemann problem and problem of nonexistence of odd perfect numbers) can suggest new (quantum) strategy of resolving.

    Dear James,

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

    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, `

    Dear James Lee Hoover!

    You have raised many questions in your essay that are addressed to future science. We hope that the human mind will not meet the limits and will develop. We positively perceived your essay and evaluate it positively. We appreciated your essay to the maximum, we liked everything!

    We share your aspirations. Successful flight of your thoughts! We think, which means THOUGHT EXISTS!

    Truly yours,

    P. Poluian and

    D. Lichargin,
