THE HIDDEN MATTER COLLECTION
Send a beam through a sealed specimen. Read its density.
Reconstruct what the light cannot show.
6 specimens to uncover
Click a cell to cycle its material. Keyboard: arrows to move, 0 / 1 / 2 to paint.
HOW TO READ THE INVISIBLE
A beam through void, stone and ore reads 0 + 1 + 2 = 3. Hover or focus a reading to illuminate its path. Match your model to each scan. Diagonal views break ties that rows and columns leave behind.
Scan all four views to certify a reconstruction. There is no timer. Hints reveal one cell; undo is free. Completed specimens are saved on this device.
INSPIRED BY CURRENT SCIENCE
Inspired by 2026 research into laser-driven muon imaging. This original puzzle uses exact, simplified density sums, not a physical muon simulator. Real instruments infer material from particle transmission and scattering.
