Dear Prof. Dr. Ali Chamseddine:

I have more questions than answers. Because I ask many highly-respected scholars some of these questions, a few are quick to assure me that they have the right answers. Most of the big bang advocates will not look at our numbers (a chart of 202 notations from the Planck units to the age and size of the universe) whereby a primeval length-and-time and mass-charge naturally inflates. It is a bit disappointing.

Warmly,

Bruce

My Pi Day Greeting to you all: https://81018.com/challenge/

Gentlemen:

Congratulations on your Spectral Standard Model. It seems we may be going over some of the same grounds, however you all are scholars and ostensibly I am a high school person who happened to slide down into Alice’s rabbit hole and looked up from the Planck base units thinking, “How am I going to figure this out?”

I have previously communicated with Alain Connes and now with this note, with your third expert, Walter van Suijlekom. Also, I am now starting to engage the work of Viatcheslav Mukhanov. It looks as if he may be an occasional associate of your group.

You all are doing such marvelous work I am now attempting to hire a tutor to be sure I am understanding you all correctly. Thank you for all that you do.

Warmly,

Bruce

PS. I had also arrived at the volume of the universe ∼10^{60} in Planck units using 539 tredecillion units per second (Plank Time) over the current age of the universe in seconds. A coincidence? Significant? Thank you.-BEC

RE: Can we open up — at the same time that we “drive down deeper” into — the Spectral Standard Model so that the Planck base units come up to meet us at the neutrinos?

Dear Prof. Dr. Ali Chamseddine:

Never have I read somebody’s construct that affirmed the primacy of the Planck Length as I find in your ArXiv article, *Noncommutative Geometry and Structure of Space-Tim*e, May 2018, “We establish the existence of two kinds of quanta of geometry in the form of unit spheres of Planck length.” Then: “At present the volume of the universe is∼10^{60} in Planck units [17]. In the noncommutative approach, and because of the need to have compact spectrum for the Dirac operator, space-time is taken to be of Euclidean signature.”

I am spellbound by your work. Thank you.

Warmly,

Bruce

PS. I have had a checkered career, yet in 2011 I was helping my nephew with his geometry classes in a New Orleans high school. We were studying the interiority of the tetrahedron and octahedron, when Zeno came into the picture and we started walking back inside by dividing the edges by 2, connecting the new vertices, and “shrinking down.” In just the 45 steps we were in the domain of particle physics. In an additional 67 steps we were within Max Planck’s domain. We learned a little about Planck and Euler, so used Planck’s base units to multiply our way out of there. Of course, in 112 steps we were back in the classroom, and in another 90 steps we were out on the edges of the current expansion — Just 202 groups or base-2 notations.

Our 2016 chart of numbers: https://81018.com/chart/ Our very first chart in 2011 of just Planck Length extensions: https://81018.com/big-board/ I thought you might find this work of some interest. We need a lot of help to sort it out. Thanks again. -BEC
