Dear Prof. Dr. Paul Halpern:
Three years have passed since contacting you about your work and our work. You should also know that you were one of the first globally-recognized scholars to whom we wrote about our work back in 2013.
Our most recent analysis is always the homepage: http://81018.com
Our numbers are all here: https://81018.com/chart/
It is still as idiosyncratic as ever. We are still asking scholars, “Where does our logic fail to compute?” And, we still have not received an answer so we keep trudging along this path!
Best wishes,
Bruce

RE: “Edge of the Universe: A Voyage to the Cosmic Horizon and Beyond” (Wiley 2012).
Dear Prof. Dr. Paul H. Halpern:
Extraordinary. Congratulations on such a prolific career.
Given your work, I think you could have a rather quick response to a difficult question:
Is 1.03885326 × 1026 meters a good figure to use as a measurement to the edges of the observable universe?
We are five high school geometry classes and their teacher’s uncle who sometimes helps out. We began this project just over a year ago. Probably we are so far off the mark, it is just silliness.
