Dear Prof. Dr. Carl J. Hogan,

I discovered your article, *Symmetries of the Primordial Sky*, and was immediately attracted to it and immediately went and opened the ArXiv edition.

Fascinating. Engaging. At about that time, I had set aside my writing to Joanne Baker of *Nature *magazine; and now, thinking of your work, you were inspiring me to be bolder.

As I read your abstract, I could hear myself saying, “Check. Right. Right. Right. Check…” So, now I need to dig into the article and also look at all your other work to see just how bold I can be if I were to write to you. Eventually, you’ll know, but for now, maybe we can be friends.

So, I just did a brief survey of your work. First, “Congratulations on all that you have done. You have done quite a sweep of the world and the universe! As a sequel of *Symmetries… *I think you could begin to answer some of our many unanswered questions.

You begin the dialogue with the reader, “The world works according to two all-encompassing theories…” and you are so right. *Our world* has done well with those two theories. *Our universe*, on the other hand, demands that the two come together.

First, let’s push our understanding of time. We are all so infinitely Newtonian when finite seconds do just fine. Here’s is our look at what we called, The Universe Clock. We start at the Planck base units and assume Planck Time is the smallest unit and the first unit. That work in 2017 was part of a NASA Space App exploration at their facility in Huntsville. We thought we had emerged with our own homegrown STEM tool and began sharing it with other high schools. It came with a rough outline of the universe in 202 base-2 notations. We had started learning a little cosmology and theoretical physics; Frank Wilczek’s books were helping to guide us and an old friend, Freeman Dyson, was trying to keep us on the straight and narrow.

Yet, there was something fundamentally wrong with our model. It didn’t cotton with big bang cosmology. It had at least 64 notations before particle physics and CERN’s measuring devices. Our little model was puzzling yet logical. How could we be so far off and out of step?

I decided that pi was our stumbling block. It was tied up inside so many fundamental equations that describe fundamental things and nobody was talking about its essence and as a starting point. The more I learned about Hilbert, Gödel, and infinity, it seemed a simple redefinition was in order. Might pi provide the simple bifurcation whereby the infinite is qualitative that is continuity/order, symmetry/relations, and harmony/dynamics and finite is the always a quantitative expression?

It gave me a slight reprieve so our 202 notations could stand, and time and space could be inadvertently redefined so all notations could become *always active*. There is so much more that we’ve slowly uncovered, but I have already overstayed a *de facto* time allocated to emails such as this. So let me say, “Thank you, thank you, thank you for all that you do, and for taking time to write about the *Symmetries of the Primordial Sky*. I have questions, but on my continued survey of your work, I know you do not have the time. So, let me ask for permission to write again. Thank you.

Most sincerely,

Bruce

**Symmetries of the Primordial Sky Abstract** (PDF):

Quantum field theory, which is generally used to describe the origin of large-scale gravitational perturbations during cosmic inflation, has been shown to omit an important physical effect in curved space-time, the nonlocal entanglement among quantized modes from their gravitational effect on causal structure. It is argued here that in a different model of quantum gravity that coherently preserves nonlocal directional and causal relationships, primordial perturbations originate instead from coherent quantum distortions of emergent inflationary horizons; and moreover, that causal constraints account for approximate symmetries of cosmic microwave background correlations measured at large angular separations, which are highly anomalous in the standard picture. Thus, symmetries already apparent in the large-angle CMB pattern may be unique signatures of the emergence of locality and causal structure from quantum gravity.

Questions related to approach to QFT:

1. Does QFT apply to Planck scale physics?

2. Might the profoundly infinitesimal universe (below the measurements of CERN) be perfectly smooth?

3. Might quantum physics be a question of geometry?*More to come…*
