Dear Prof. Dr. George Efstathiou:

Life is so short and we have so little time, we must be frank with each other. Brutally honest. Also, with people like Biden and Putin with their hands not far from nuclear triggers, our world is desperate for a new model of who we are and why. There is a Wheeler-like, most-simple mathematical alternative to big bang nihilism: Base-2 applied to (the expansion of the Planck base units, Stoney base units, or ISO-NIST new base units will do because all three define just 202 notations which are further defined by a continuity-symmetry-harmony inherent within infinitesimal sphericals that create the grid about which Wilczek and others have written.

In this light, I have five key questions for you. These questions drive our homepage where you will find a paragraph referencing your work and also linked to our reference page about your work: https://81018.com/efstathiou/

Thank you.

Most sincerely,

Bruce

Footnote: **Those five key questions are**:

- Is the universe essentially and foundationally exponential?
- Is the first very moment in time defined by the equivalent of the Planck base units, all natural units?
- Does pi dominate those natural units such that the first manifestation of spacetime is an infinitesimal sphere whereby three fundamental qualities of pi are instantiated in everything-everywhere throughout all time; that is continuity-symmetry-harmony?
- Is there a thrust whereby, if the 1899 Planck numbers are used, there is one infinitesimal sphere per unit of Planck Time and Planck Length. Would that compute to around 539 tredecillion spheres per second? If using the 1874 Stoney calculations, would the rate of expansion be 4609 tredecillion spheres per second?
- Might the geometry of quantum fluctuations begin with the gaps of the tetrahedron and octahedron, after the first 64 notations where fluctuations are first measurable?

**This paragraph within today’s homepage states**:

[†] Another Map of the Universe. “The most detailed map ever created of the cosmic microwave background…” of the universe was done in 2009 when the Planck satellite measured the CMB (Cosmic Microwave Background radiation or CMBR). Scholars like George Efstathiou, director of the Kavli Institute for Cosmology at the University of Cambridge, believe it is “380,000 years after the big bang.” For us, time and temperature are works-in-progress; there are so many open questions. Our little map of202 notationsmathematically encapsulates everything, everywhere for all time so we are working to grasp the fullness of the Efstathiou 380,000 years, and his time-stamp, “after the big bang.”

Second email: October 2020

Dear Prof. Dr. George Efstathiou:

I just checked my email and I am not sure if you received our email back in August of 2018. It is quite obvious that we believe you are among the wise and you could appropriately caution a bunch of high school people. We have worked very hard to see the correlations between mathematics and physics. Surely you have been studying these things much longer and much more deeply than we have. Yet our work is done earnestly. Thank you for any guidance you might give us. It will be strictly confidential. Thank you.

Bruce

Dear Prof. Dr. George Efstathiou:

We have a scale transformation problem and only wisdom can help us resolve our conundrum. You’ve got wisdom. If you could take a moment to take apart our simple mathematical construct, I will be eternally grateful.

But first a little disclaimer.

Our work started within a high school geometry class where we emerged with a totally mathematical but rather idiosyncratic view of the universe. We went deep inside the tetrahedron by dividing each of the edges by 2. Initially we encountered the four half-sized tetrahedrons in each corner and the octahedron in the middle. We continued that process with both objects until we were in the range of the fermion.We had divided by 2 no less than 45 times.

Just 67 *more* steps within, we were in the range of the Planck scale. We then multiplied our original objects by 2. Within 90 steps, we were within the range of the observable universe.

There were a total of 202 doublings.Our original poster is here: https://81018.com/big-board/

Our earliest discussion here: https://81018.com/home/

Our current chart with the four Planck base units: https://81018.com/chart/

Does it make any sense? Can we use the Planck scale in such a manner? Is it logical? Is our sense of the doubling functions appropriate? Is it just too simplistic? If so, could you help us articulate our failure of logic?

Bruce
