Planck evidence for a closed Universe and a possible crisis for cosmology
Nat Astron (2019) doi:10.1038/s41550-019-0906-9

Planck cosmic microwave background spectra now preferring a positive curvature at more than the 99% confidence level. Here, we further investigate the evidence for a closed Universe from Planck, showing that positive curvature naturally explains the anomalous lensing amplitude, and demonstrating that it also removes a well-known tension in the Planck dataset concerning the values of cosmological parameters derived at different angular scales.

Editor’s note on July 17, 2020:  This sloppy thinker can’t believe that just nine months ago, I thought the base-2 chart was a closed system. It’s not. It is open. I’ll be going over this email a few more times to try to discern why I came to this conclusion. -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 understanding of our actual reality. 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 a simple closed universe. Totally idiosyncratic, it should open many new doors to explore. That could be quite exciting.

First, we find the 202 notations: https://81018.com/chart/
That link opens to all the numbers horizontally scrolled.
Then we’ll find the first 64 notations that are virtually unexplored.

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 compares 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!
