We have reached the bottom
We have blueprinted the quantum level engine out of magnetized plank cube base level building blocks.
It is now known to humanity, even if you resist as you did germ theory, as you did the placement of the earth among the cosmos, as you did our path of evolution.
The Sommerfeld constant, or the FSC (Fine Structural Constant) Alpha, is not the shadow, but the source of the light, casting the shadows outward.

Alpha
α = 137.035999

e is the elementary charge = 1.602176634 × 10 to the −19 C
h is the Planck constant = 6.62607015 × 10 to the −34 J⋅Hz
-ħ is the reduced Planck constant = ħ = h/2π (1.054571817...×10 to the −34 J⋅s
c is the speed of light = 299 792 458 m⋅s
ε0 is the electric constant = 8.8541878188(14) × 10 to the −12 F⋅m

We see these as numbers, measurements adding together to give us a new experimental observation, a new number, α for Alpha
Yet it is α that is the source of the other numbers.
The light source casting the shadows upon the walls of Plato's cave.
Manufactured through the build, though the emergent quasi particle layers, through the circuits, the times, the dimensions, the layers, the plank level sizes, the observers, all of the ratios are but a single ratio of the plank cube, and the total quantity of cubes that exist in the universe (Pi, which will be a large yet rational number).

Let us build, our Universe building machine.
α + α = 2α, α + 2α = 3α, α + 3α = 4α...
Our simple original number reproduces with it's own errors, stamping out the parts as we go.
Shall we crack on?
