**1955…**

Princeton physicist, John Wheeler, wrote this unusual combination of words for the first time. Today, also known as spacetime foam,** **it has been suggested that this *foam* marks the beginnings of** **quantum mechanics. Also, the study of foam has evolved to spin foam theory and spin networks (Roger Penrose, 1971). It is now a key topic within loop quantum gravity (LQG).

**Who Is John Wheeler and what is this foam? **This page is simply to aggregate as many articles as possible about quantum foam beginning with an introduction to John A. Wheeler and his work:

**A different approach**. As you might imagine, within this website, the concepts of *quantum foam* and quantum fluctuations are treated rather differently. This will be our first attempt to describe both within the context of the 202 base-2 notations. Many updates are anticipated.

First, within our 202 notations, quantum mechanics does not begin in the first notations. Here, quantum fluctuations, which are assumed by most scholars to be responsible for the quantum foam, are associated a very real geometric configuration. With just five tetrahedrons sharing a common edge (as shown), there is a natural gap within that pentagonal structure which is then extended into the 20-tetrahedral complex or icosahedral complex which is then extended into the 60-tetrahedral Pentakis dodecahedral complex. It is hypothesized that the mathematics of the gap is the mathematics of Wheeler’s quantum foam which is the mathematics of quantum theory. At this time, it is not known within which notation the pentagonal structures first manifest.

**Does the sphere become an incompressible foam?**

At the Planck scale (A0) and its first doubling or notation (A1), circles and spheres are strictly mathematical. Physical manifestations cannot be measured until those doublings are in the range of today’s CERN scale. Yet, by our analysis of the 31st notation, there is a very real mass and charge. Nevertheless, at the A1, the circle and sphere are mathematically defined by dimensionless constants and this so-called foam is an *absolute* limit of space-time (Planck Length-Planck Time).
