Everything humanity still can't explain — from dark energy to the Voynich manuscript to the Illuminati — in 29 categories and ~190 items, each with its own illustration. Every entry is tagged on a confidence spectrum, so a genuine open question is never confused with a debunked conspiracy.
Built across multiple adversarially-verified research passes. Tap a legend chip to filter.
Reading the gradient: 🔬→🛸 are honest unknowns. 🟠 is where a real event grows a conspiratorial shell. ⚠️ is belief without evidence. The most interesting items sit on a boundary and migrate — UAP slides 🛸→⚠️ exactly at the "it's aliens" claim; simulation theory straddles 🔬/⚠️. Icon color = confidence tag.
