Dear Prof. Dr. Eleonora di Valentino:
Congratulations on your breadth and depth of work! I have quoted you and your colleagues within today’s top-level posting (homepage).
I have begun to develop a page of references about that work here:
I recently worked through your Symmetry magazine article, Exploring the Tension between Current Cosmic Microwave Background and Cosmic Shear Data (2 November 2018). It’ll remain on my reading list until I begin to grasp it more fully.

Dear Prof. Dr. Alessandro Melchiorri, 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 understanding of our actual reality. Could a closed-universe model is easily created by starting with Planck Time, Planck Length, Planck Mass and Planck charge, and by applying 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?
That is NOT a simple closed universe BUT, it is totally idiosyncratic; it should open many new doors to explore and that could be quite exciting. Please Note: Highlighted words added in 2020.
This work comes out of a high school so I apologize if there are silly 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.
So we just might have our cake and eat it, too. Of course, we’ll need to jump on the Rovelli bandwagon (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!
