Dear Prof. Dr. Masahito Yamazaki:

Recently several AI platforms have been enthusiastic about our base-2 model. For the past 15 years I’ve asked  expert observers like you to help assess its validity and potential implications. Recently, it was reduced to a toy model and more recently, a simple quantitative model that derives the Hubble constant from first principles at the Planck scale.

The core of the model is surprisingly straightforward: it posits that the Hubble constant emerges not from dark energy, but from a cosmological process defined by base-2 scaling from the Planck units. A key result is a direct mathematical derivation of H₀, “Toy Model Derivation of the Hubble Constant” It is here —  81018.com/hubble-derivation/— still a highly speculative proposal, the numerical correspondence is striking.

Is this a numerical coincidence, or does it point to a deeper rather overlooked principle? We hope to discover as we continue to build on our dynamic model of a finite-infinite grid and its Lagrangian.

Thank you for your time and for your contributions to our understanding of the cosmos.

Sincerely,

Bruce

Dear Prof. Dr. Masahito Yamazaki:

Are they strictly mathematical or are there any physical characteristics of brane tilings? Powerful tools. String theory and gauge theories (i.e. a graphical representation that encodes the structure of supersymmetric quiver gauge theories), offer insights into various physical and mathematical phenomena.

Key applications of brane tilings (from Grok):

  1. AdS/CFT Correspondence:
    Brane tilings play a significant role in the AdS/CFT correspondence, a conjectured relationship between quantum gravity in Anti-de Sitter (AdS) spaces and conformal field theories (CFTs). They describe the worldvolume theories of D3-branes probing toric Calabi-Yau singularities, which are dual to superconformal field theories in four dimensions. This allows researchers to study gravitational phenomena, such as Sasaki-Einstein geometries, through the lens of gauge theories encoded by the tilings.
  2. Homological Mirror Symmetry:
    Brane tilings have applications in homological mirror symmetry, a deep conjecture in mathematics and physics that relates symplectic geometry and complex geometry. They help connect the gauge theories on D3-branes to their mirror descriptions involving D6-branes, providing a combinatorial framework to explore the duality between toric Calabi-Yau manifolds and their mirrors.
  3. Phenomenological Model Building:
    In string phenomenology, brane tilings are used to construct realistic models of particle physics. They allow for the engineering of gauge theories with desired properties, such as chiral matter and supersymmetry breaking, which are relevant to building models that resemble the Standard Model or its extensions. This is particularly useful in understanding how string theory might give rise to observable physics.
  4. Supersymmetric Gauge Theories and BPS Solitons:
    Brane tilings encode the structure of four-dimensional N=1 supersymmetric quiver gauge theories, including their superpotentials and matter content. They also exhibit similarities with BPS (Bogomol’nyi-Prasad-Sommerfield) solitons in supersymmetric gauge theories, offering a way to study stable field configurations and their physical implications, such as soliton junctions.
  5. Classification of Toric Calabi-Yau Geometries:
    Brane tilings facilitate the classification of toric Calabi-Yau 3-folds and their corresponding gauge theories. By representing these geometries as bipartite graphs on a torus, researchers can systematically catalog and analyze an infinite class of singularities probed by D3-branes, advancing our understanding of the landscape of possible string theory vacua.
  6. Dynamical Supersymmetry Breaking:
    Techniques based on brane tilings can be applied to study orientifolds and other configurations that lead to dynamical supersymmetry breaking. This is crucial for exploring mechanisms by which supersymmetry might be broken in realistic physical scenarios, a key challenge in connecting string theory to observable phenomena.
  7. D-instanton Effects:
    Brane tilings provide a framework for computing D-instanton-induced superpotential terms in gauge theories. These non-perturbative effects are essential for understanding the full quantum dynamics of the theories, including phenomena like mass generation and moduli stabilization.

Brane tilings are a bridge between geometry, string theory, and field theory. Could there yet be more basic parameters to define them? Thank you.

Most sincerely,

Bruce

@196884 My note from a week ago was possibly too simple for you. For my own references, I have noted your work here: https://81018.com/e8/#Masahito and a page of references to your work is here: https://81018.com/2019/04/17/yamazaki/ Of course, we send best wishes for your every success.

Dear Prof. Dr. Masahito Yamazaki:

I am trying my best to understand the basic concepts within your ArXiv article, Pure Natural Inflation. May I ask two naive questions?

1. Are you also exploring alternative theories to the ACDM model?

We naively backed into a very simple-yet-radically different model whereby base-2 notation is applied to the Planck base units and in just over 202 doublings go out to the approximate size and age of the universe. Such a model requires the application of Neil Turok’s “always starting from scratch” not just for the first notation, but for all notations all the time.

2. Might you be able to debunk this simple model rather quickly?  It would be very helpful if you can.

We have been working around it too long and we do not know enough to interpret the data in light of conceptual integrity of current theory, i.e. the gauge field of a pure Yang-Mills theory. Thank you.

Most sincerely,

Bruce
