Where is Mind? Orders of Magnitude

Our minds conceptualize galaxies billions of light-years away and grasp the composition of tiny atoms, too small to be observed by any known tools. Our minds consider our physical being, in addition to reflecting on consciousness and existence. Where is this thing we call a mind? And, how is it that the mind has such an expansive grid of intelligibility?

Energy, matter, life and mind are all part of nature, as we know it. Each component possibly plays a different role at specific orders of magnitude. Modern science observes differing versions of physical laws of nature at different sizes, such as: Newtonian results for humans, quantum results for photons, and relativity theory for galaxies. These different laws exist synchronously in a universe of vastly different sizes despite our inability to understand all the pieces of the puzzle.

Humans lay at the center of a broad physical range of complexity, ranging from the Planck size (30 orders of magnitude smaller) to the visible universe of galaxies (30 orders of magnitude larger). Is this central position, if understood, vital to explain living beings?

The way that mathematics describes these sizes is using the powers of ten.  If a human is a “one” in size, then a village may be 100, a region 1000.  This is written as 102, and 103. An organ of the body would be 1/10th of the size of the human.  This is written 10-1.  So in this way the distance from the surface of the earth to the center of the earth is 107, and the size of a microbe is around 10-5.  

As a rough reference below are some approximate sizes from the smallest to the largest physical beings in the known universe.

Future posts will observe new scientific data that helps us consider where, in this vast array of universal sizes, the mind might be.
