Move through six teaching bands. The control is a conceptual ladder, not a logarithmically accurate map.
Current band
Teaching model. Distances and object sizes are not drawn to a shared physical scale.
Three reality checks
A useful diagram can preserve sequence, ratio, topology or appearance—but rarely all at once across cosmic orders of magnitude.
