Infinite Galaxy Puzzle


Have you ever done a puzzle that has no beginning or end? Where you don't know up from down? The Infinite Galaxy Puzzle is a new type of jigsaw that tiles continuously. It has no fixed shape, no starting point, and no edges. It can be assembled in thousands of different ways.

Topologically, the Infinite Galaxy Puzzle maps to a real projective plane, an impossible 3D shape with a mathematically indistinguishable inside and outside. This means that it tiles with a flip, and pieces from one side attach to the other only after turning it over. Just like a Mobius strip has only one surface, the puzzle has no up or down side and can be started anywhere on any side, making it extra challenging.

This puzzle is adorned with a photograph of Westerlund 2 from the Hubble telescope. The image is continuous from one side of the surface to the other, so it can't be seen all at once. This design also features special space-themed whimsy pieces.
