Yes, you are back up on our homepage today: http://81018.com Tomorrow or soon thereafter: https://81018.com/believed/

Essentially, inspired by Murray Gell-Mann, I thought you would want to know.

In light of the Ellis Physics on Edge harangue, virtually touching everyone who has been a leading thinker in the past 20 years, right to the final paragraph with Dawid-Rovelli, I repeat the John Wheeler 1986 statement within his article, “How Come the Quantum?” where he says, “Behind it all is surely an idea so simple, so beautiful, that when we grasp it — in a decade, a century, or a millennium — we will all say to each other, how could it have been otherwise?”

The simple numbers bear him out: https://81018.com/chart/ Simple processes, like Euler’s equations and base-2 notation give us an entire range of unexplored numbers from the second notation to at least the 64th notation. That’s a science unto itself. Pure math, the string theorists could finally claim a home.

It is easy to write off simplicity, yet someday these numbers will be explored by the likes of somebody as informed as you are. Thank you.

Most sincerely,

Bruce

Perhaps the earlier email (below) was buried. Perhaps this base-2 model is just too absurd to acknowledge. I am just a simple guy following simple logic.

On one of our homepages I suggest that these are our primary assumptions:

1. The Planck base units of length, time, mass and charge describe a real reality.

2. The conceptual door to this infinitesimal universe is where all four Planck base units concresce (grow together, yet individuate) to create a stream of infinitesimal spheres. Though physical, length-time are well below thresholds of measurement, the progression of mass-charge units can be studied. These four units are, in some manner of speaking, the Janus-face of each other and of light.

3.Conceptually, sphere stacking becomes cubic-closest packing; tetrahedrons and octahedrons emergeDoublings beginOur universe emergesTheir numbers eventually begin to define things within our current scientific realities.  This is a natural inflationAnd, it’s not dark.

Since December 2011, I have been carrying on in this light, slowly, intentionally, but naively. I wish somebody of your stature and command of all the academic fields involved would take a moment and put a stop to this effort if it is sheer poppycock.  Thank you ever so much.
Sincerely,

Bruce

Dear Prof. Dr. Renate Loll:

Thank you for all your work linked (just above), particularly your efforts to discern “…a consistent theory of quantum gravity which describes the dynamical behaviour of spacetime geometry on all scales.”

Our focus has been on the Planck scale. We believe there it has more to contribute than meets the eye.

Between the Planck scale and “CERN-scale of measurements,” there are 67 doublings (or notations or causal sets) of the Planck base units. Perhaps it might be better to start at the first doubling and to observe the logical possibilities. Essentially we’d be building a unified theory of mathematics, yet this one would be based more on John Wheeler’s sense of simplicity (I love his introduction of this article, How Come the Quantum?) than on Robert Langland’s programs. Langland’s needs the plancksphere that both Max Planck and Wheeler anticipated. Might other factors like Causal Dynamical Triangulations (CDT), Regge calculus, fractal structure, 2-D spacetime, and the flavors of the simplex be included in an appropriate build-out and within an appropriate doubling? I think that the emergence at the Planck base units, the simplest plancksphere may well account for what we know as dark matter and dark energy. I believe it’s a relatively simple calculation.

Among all the people to whom I write, I suspect you can debunk this concept most quickly; or, you may be surprised at its simplicity and possibility. Of course, the derivative, discrete nature of space-time is necessary and I think we would do well to redefine the infinite with mathematical terminology and anticipate a finite-infinite transformation possibly further defining the renormalization process..

To say the least, I would enjoy hearing from you.

Most sincerely,
Bruce

PS. I first became aware of your work through the Perimeter Institute’s 2016 conference, Time in Cosmology I write letters to focus my thoughts in conjunction with the thoughts and work of a person who appears to be vibrant, open, in love with life, and filled with questions.


Follow-up (from CDT and Cosmology):
•  Non-renormalizability of perturbative quantum gravity
•  FLRW paradigm:  Physics Beyond the Standard Models of Particles, Cosmology and Astrophysics

•   Imposing homogeneity and isotropy on spatial slices of constant time t.
•   So-called “backreaction” effect of inhomogeneities on smaller scales on the dynamics of the universe on larger scales
•   “…an explicit realization of a non-perturbative, Planckian quantum dynamics…”


More Work to do (further research):
•  Path integrals and Gaussian fixed point. See Assaf Shomer’s on page 7: “The derivation of the path integral formula in quantum mechanics of a massive particle involves chopping up the quantum evolution into very short time intervals and inserting complete sets of states between them.”
