Imagination and real science

Parallel Planets is an imagined storyworld. Real science pages explain the underlying ideas and link to sources. Games use simplified models; they do not replace real observations or predict local tides.

A calm website

The website has no autoplay video, advertising or time pressure. Reduced-motion preferences are respected. The tide game has its own motion setting. Quiet stories can support a calm moment, without promising sleep or learning outcomes.

Watching on YouTube

Watch links leave this website for YouTube in the same tab. YouTube controls its own videos, recommendations, advertising and data practices. A grown-up can choose what to watch and stay nearby.

Progress stays in this browser

The tide game can save settings, observations and a badge on this device. There is no account or cloud sync. Clearing saved progress in the game also removes its stored settings. Browser data clearing can remove progress too; saving is not required to play.
