The number keeps its meaning.

What this measurement describes

Depth is a directional distance below a surface or reference level, not the size of a solid object.

02 · Deep

How certain is the boundary?

This is an observed measurement. The displayed precision follows the cited reference and should not be read as infinite accuracy.

What the engine actually divides

Vastoscope compares the SI value in metres for this measured seafloor depth. A ratio is mathematically valid as a linear span, while the interface identifies when the two selected definitions differ.

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.
