Thanks to the James Webb Space Telescope (JWST) and Space Telescope Science Institute for supporting this video.
This video is about the cycloid curves on Jupiter’s moon Europa – they’re ridges or valleys in the icy surface that formed due to some sort of geological or tectonic-esque phenomenon. The answer involves ping pong balls, the pacific ring of fire, subduction, tidal bulges, and tailcracking,
