Semantic Gravity
Embedding space as a gravity field: topic planets pull a query packet with force equal to cosine similarity — but their SIZE shows keyword overlap. Predict where the query lands. The big planet sharing your keyword pulls like it skipped leg day.
The one rule of this game is the one rule of vector search: mass is meaning, size is spelling. Every planet’s gravity equals its true cosine similarity to the query; every planet’s visual size equals its keyword overlap. They are usually not the same planet.
Six queries from real engineering life. Read each one, click the planet you think captures the packet, then watch Newton run the retrieval. After each round the actual cosine scores are revealed, with a note on why the keyword-trap planet lost (or, occasionally, why two clusters were legitimately close — which is exactly why you retrieve top-k and not top-1).
Same inverse-square physics as Gravity Courier and the 🪐 simulation in the header. Best score saved to localStorage. Single HTML file, no dependencies.
