Geometric or Pentagonal Gap: The first little-known gap that we studied was created by five tetrahedrons. Beginning in 2016, it has been a key part of our analysis of numbers, geometries, chaos, quantum fluctuations, and human will. Is it possible that this little gap could be the basis for diversity, creativity, openness, indeterminism, and uniqueness?  In 2022 we also began to consider the pentagonal gap uncovered a gap by five octahedrons sharing a centerpoint and each octahedron sharing at least one face. That gap was hidden by the geometry construction sets. There are also the icosahedronal gaps, and the Pentakis dodecahedral gaps that are extensions of the five-tetrahedrons.
History: Aristotle had it wrong ; he claimed that he could perfectly tessellate the universe with tetrahedrons.  We believed him for over 1800 years. However, if you have five perfectly shaped tetrahedrons, the imperfection is easily observed. That gap is a seminal shape. Tetrahedrons have four vertices. Octahedrons have six. Five regular tetrahedrons have seven or eight vertices. Cubes have eight. This progression is important.
The gap appears to be transcendental, non-repeating, and never-ending.
Of course, together with a ratio of two tetrahedrons to one octahedron, you can create a whole, ordered, rational, and perfect object that will perfectly tile and tessellate the entire universe.
The indeterminate and chaotic reside somewhere deep within the structure of the universe. We believe that place just may begin right here with the “Pentastar Gap.”
Here may well be the basis for broken symmetries. Of course, for many readers, this will be quite a stretch. That’s okay. For more, we’ll study chaotic maps, the classification of discontinuities, imperfections, and quantum fluctuations. More…
The Pentastar logo by Chrysler has a fan club! Now that Fiat’s involved, the Pentastar logo is being flushed out of their branding. There is a group of over 13,000+ advocating that they continue using it. I suggested in a note to them, “Chrysler made it an artform! The gap is the beginning of quantum fluctuations. It is the beginning of the geometry of living.”
