Dear Prof. Dr. Robert Brandenberger:

I have been listening to your lecture at the Rotman Institute of Philosophy from June 12, 2017 at Western University in Ontario. I am also reading Beyond Standard Inflationary Cosmology while you talk.  Every once and awhile, I have to look over to examine your illustrations within the lecture. And, to say the least, I am glad to hear your emphasis on the “s” of theories (as well as models).

Before going further, let me say that you project a sensitive and honest integrity that just might tolerate the strangeness of our simple work.

We backed into cosmology through a high school geometry class where we were watching the embedded geometries of our tetrahedrons and octahedrons become increasingly smaller. The initial edges were just two inches. Within just 45 steps our numbers were in the range of the CERN-scale.  In just 67 more steps we were touching the Planck Wall  defying Zeno’s paradox. When we multiplied by 2, our little geometry exercise opened the windows of cosmology. In just 90 more doublings, we were approaching the Age and Size of the Universe. There were a total of 202 doublings from the Planck scale!

That was December 2011. We’ve are not what one might call a “quick study.”  We initially thought of our chart as a good STEM tool. In April 2016, after developing many different visual aids, we evolved with a horizontally-scrolled chart that allow a closer examination of the natural inflation of the numbers: https://81018.com/chart/

I know how idiosyncratic it is. Still there is enough logic and commonsense and simple math that we continue our explorations.  Might you comment on this work? Have we totally lost it or is there some possibility that this model can begin to breathe?

Thank you.

Most sincerely,

Bruce
