Dear Prof. Dr. Alessandro Melchiorri:

I was among those who were challenged by your 2019 Opened/Closed article. It seemed like commonsense. Of course, the universe was opened.

Three years later, we have nothing conclusive, so might I suggest that we try to start again from scratch? Where would you begin? Don’t we all are need a paradigm shift? How about this for a start: 

1. Might we assume infinitesimal units on the order of Planck/Stoney define the first moment in time?
2. Might we assume that one infinitesimal sphere manifests per infinitesimal unit of time?
3. If so, we can readily assume between 539-to-4609 tredecillion spheres per second.
4. If so, assume both attractor theory and the Fourier transform have key roles.
5. If so, assume Langlands programs and string-and-M theory have key roles.

Might we have the making of an ALT model of the universe that James Peebles could participate in?

Thank you.

Editor’s note:  In what ways could our base-2 chart be a closed system? It seems quite open and evolving. I’ll be going over this email quite a few more times to try to discern, Open? or CLOSED? -Bruce

Dear Prof. Dr. Alessandro Melchiorri (Corresponding Author),
(and Prof. Dr. Eleonora Di Valentino and Prof. Dr. Joseph Silk):

There should be no crisis for cosmology!

We all want to live within the best possible understandings of our actual reality. I’ve had to ask, “Could a closed-universe model be created by starting with Planck Time, Planck Length, Planck Mass and Planck charge? If we apply base-2, encapsulating the universe within 202 exponential notations that start at the very first moment of space and time and goes to the current age-and-size of the Universe, it is not closed. The Now is still happening, evolving, unfolding from a finite-infinite relation. In this model that relation is dynamic, always-current, and it is defined within pi. It may not satisfy some people’s need for a more robust sense of the infinite, these definitions go as far as we need to go at this point in time.

First, consider the 202 notations: https://81018.com/chart/
That link opens to all the numbers, horizontally-scrolled.
Then we should explore the first 64 notations; these are virtually unexplored.

This work comes out of a high school so I apologize for any errors. Also, we did a comparison of that progression of numbers with the definition of the Big Bang epochs within the standard model: https://81018.com/calculations/  It seems to compare well.

Might we have our cake and eat it, too? Of course, we’ll need adopt the Rovelli camp (along with Richard Muller of Berkeley and others) and finally grasp a new understanding of our illusion of time’s arrow.

Thank you for all your work. Congratulations. Brilliant!
