Emails to Carlo Rovelli: loop quantum gravity theory

Dr. Rovelli said, “…and we have to learn to do physics and to think about the world in a profoundly new way. Our notions of what are space and time are completely altered. In fact, in a sense, we have to learn to think without them.” ALSO: “Our space in which we live is just this enormously complicated spin network,” said Dr. Carlo Rovelli of the University of Pittsburgh. He and Dr. Lee Smolin of the Center for Gravitational Physics and Geometry at Pennsylvania State University have figured out how to use spin nets to calculate area and volume — all this information is encoded within the web-like structure.”

Dear Prof. Dr. Rovelli:

Thank you for all your marvelous work.  You make very difficult concepts very approachable.  That helps us tremendously.

We have so little background in your world, however, in our high school geometry class, we started with the tetrahedron with the octahedron [https://bblu.org/2012/12/11/tot/] inside of it, and kept on going within, dividing by 2, until in about 45 steps we were down around the fermions and in another 67 steps we were within the  Planck base units. When we multiplied by 2, we were out to the Age of the Universe in just under 90 doublings.  Since December 2011 we have worked on our integrated UniverseView [http://bblu.org] using base-2 exponential notation as a general outline.

It is 3.333 times more granular than Kees Boeke’s base-10, it has an implied geometry, and it has the Planck base units.  Some of our current work is here: https://81018.com/  It has become quite a modelling project.

Notations 1 to 67 challenge us to rethink our understanding of the basic notions of Time and Space. Your work is helping us to see that others are doing substantial work in this area from a much more professional point of view. 

Is our work at all helpful as a framework for research?

Thanks.

PS.  We are just now starting to consider the nature of spin!

PPS.  Our first note to you was sent on Sun, May 1, 2016 but it either did not reach you or it was gobbledygook. We are trying to write as clearly as possible.  Forgive me, please, if this continues to be too strange and not very charming.  -B

Dear Prof. Dr. Rovelli:

We, too, are trying to rethink our understanding of the basic notions of Time and Space, plus light and the Planck base units. Since December 2011 we have worked on an integrated UniverseView using base-2 exponential notation as a general outline.

It is all quite a bit more granular than Kees Boeke’s base-10. Ours came out of a chase of the embedded tilings and tessellations of the octet. We were building models in our high school geometry class and decided to “go within” until we got to Planck’s base units. That was easy. Going out to the Observable Universe was easier !

It has become quite a modelling project.

Our horizontal-scrolling chart from the Planck base units to the Age of the Universe, the Now, is rather unique. There are a total of just 200+ notations!

Are we onto to something or off within some fallacy of misplaced concreteness?

Thanks.

Most sincerely,
