What this measurement describes
Distance measures separation between positions. Comparisons count linear spans; they do not turn the gap into a physical object.

The number keeps its meaning.
How certain is the boundary?
This value is fixed by scientific or international convention. The definition is exact even when a physical realization has measurement limits.
What the engine actually divides
Vastoscope compares the SI value in metres for this distance light travels in one hour. A ratio is mathematically valid as a linear span, while the interface identifies when the two selected definitions differ.

something to stand beside.
These anchors are selected by logarithmic proximity from familiar human, engineered, planetary and cosmic references.

Evidence trail
Where this scale comes from.
Vastoscope keeps the displayed number separate from its measurement type and certainty. Representative and model-dependent values are intentionally labelled instead of presented as exact edges.
