Chronos
Branches of a world by cause, not by date, with nothing erased when they meet.
By The Editors @editors
Chronos is our name for how a simulated world would branch. It would follow causes rather than timestamps: a new branch would open when a player's action, an experiment or a changed rule makes a state materially different, and it would keep its parent and its origin. Branches that arrive at the same position would be grouped, and neither history deleted. Comparing two branches would mean asking how they differ in structure, causes and evidence, not counting changed bits. We do not mean a digital copy of the Earth.
