Dear Prof. Dr. Robert Spekkens:
In 1977, I joined David Bohm and his doctoral candidates to become a point, a line, a triangle and a tetrahedron (a three-hour seminar). In 1979 Viki Weisskopf helped arranged for me to meet and have a private one-on-one with John Bell at CERN. In 1980 I sent six months studying one day with Olivier Costa de Beauregard and the next with J.P. Vigiers at the Institut Henri Poincare. Then, with my head spinning, I returned home to Boston to make a living.
In 2011 I returned to all those questions in a rather peculiar way. My nephew asked me to introduce the Platonic solids to his high school geometry students (about 80 students). Several were fascinated by the most simple internal structure of the tetrahedron and octahedron. With deference to Zeno, we started going within the tetrahedron by dividing the edges by 2. In 45 steps within we were looking at particle physics (and billions of tetrahedrons and octahedrons). In 67 more steps, we were looking at the Planck Wall and began examining the Planck base units. What happens to all those tetra-octa structures as everything infinitesimally small? We concluded, “They must be shared by everything. It’s hypostatic.”
Deciding to start with the Planck units, we multiplied back up to the classroom object and continued the 90 additional steps to the Age of the Universe and the approximate size of the universe. Of course, it is a natural inflation and at the 144th notation, we were just over one second. At the 197th notation we were at the large-structure formation of the universe. With the 202nd doubling (10.9 billion years), we are just 2.9 billion years into it. Is it at all meaningful?
