Field notes
The interface lists a scale ladder for moving between objects, a distance ruler, and search with arrow-key result selection. Its Earth-history view covers 4.54 billion years on a stretched scale, and the page cautions that the globe shows the broad look of each era rather than an ancient map. The stated date limits and astronomy methods are page claims; no data-source citation appears in the extracted material.
