Over the last several centuries, science has discovered objects in the world along a continuum of scale. In one direction, we have discovered planets and stars, as well as galaxies and galaxy clusters. In the other direction, we have found cells and proteins, atoms and neutrinos. To locate and model this world, we use the 3 traditional directions of length, width, and height. However, inherent in all our measurements is the scale of what we are measuring — a continuum we do not directly see with our eyes. The author presents the hypothesis that we need to include this continuum in a complete model of nature and our world. Why we have not already included this continuum can be traced to our lack of mathematical tools to handle the exponential structure of the measure of scale. The author presents the mathematical conjecture that the appropriate tools require a numeric representational system with more power than our traditional decimal or positional-based numerals. Such a system could provide a single value for complex numbers and make possible measurements currently invisible to science today.
