## What is Chronomap in Cosmos?

This is a specialized version of the "When-Wher-What Database" focused on the cosmos. It features the ability to display "what happened where and when in the universe" by intersecting the heliocentric ecliptic coordinates with the time axis. Of course, it also includes the functionality to contribute data to the "When-Where-What Database".

The "When-Where-What Database" is a project where users collaborate to build a comprehensive database that covers all historical events from the origin of the universe to the endless "now," regardless of the field. It aims to accurately display not only "when" but also "where" events occurred, emphasizing both temporal and spatial distances.
