First / An exact finite reference
Less contrast. A smaller cell.
A gentler contraction.
Follow the same small material cell through the paper’s flat, homogeneous reference solution. The selected response weakens, its negative pressure brakes the contraction, and its density increases. Every percentage compares that quantity with its own starting value.
- Selected contrast
- 100.0% A linear matched response
- Contraction speed
- 100.0% Rate of change of the cell’s linear scale
- Matter density
- 100.0% Energy per physical volume
- Energy in this cell
- 100.0% The same shrinking material cell
At the start, all four comparisons are normalized to 100%. The cell is already contracting.
Density can rise while energy in the cell falls: the volume is shrinking, and the conserved source obeys pressure work. Here the contraction speed |ȧ| falls even though the fractional rate |H| rises.
Reference interval: d = 1/2 to 1/4; elapsed proper time in model units hΔt = 0.000. This finite example remains on the metric side throughout.
At the end of this exact reference, selected linear contrast is 50% of its starting value, the linear scale is about 54.9%, and contraction speed is about 68.6%. Density reaches 156.25%, while the energy of the same material cell falls to about 25.9%. The elapsed model time is log 2.
