Sloan Great Wall

≈1.37 billion light-years

A colossal arrangement of galaxy clusters and filaments discovered in large redshift surveys.

Wonder
Its name describes a connected pattern, not a physical wall.

What this measurement describes

The selected measurement follows the object’s longest or specifically defined linear direction.

02 · Deep

How certain is the boundary?

The value depends on a scientific model or inferred boundary. It is not a directly touched physical edge.

03 · Compare

What the engine actually divides

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

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.
