Extraterrestrial Cycloids - Why Are They on Europa?

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, REFERENCES Europa image: https://upload.wikimedia.org/wikipedia/commons/8/82/PIA19048_realistic_color_Europa_mosaic.jpg Europa “google maps” explorere: https://www.mapaplanet.org/explorer-bin/explorer.cgi?map=Europa&layers=europa_galileo_bw&west=180&south=-90&east=-180&north=90¢er_lat=0¢er=0&defaultcenter=on&grid=none&stretch=none&projection=SIMP&advoption=NO&info=NO&resolution=2 Cycloid: https://en.wikipedia.org/wiki/Cycloid Formation of Europa cycloid cracks: http://pirlwww.lpl.arizona.edu/HIIPS/Publications/hoppa_abstracts/cycloid.html Smashed ping pong ball: https://www.researchgate.net/figure/222359947_fig2_Ping-pong-balls-are-good-macroscopic-examples-for-shells-as-they-display-the-main Dented ping pong balls: http://www.katharine-yi.com/uploads/1/8/4/0/18406703/1399540277.png Support MinutePhysics on Patreon! http://www.patreon.com/minutephysics Link to Patreon Supporters: http://www.minutephysics.com/supporters/ MinutePhysics is on twitter - @minutephysics And facebook - http://facebook.com/minutephysics And Google+ (does anyone use this any more?) - http://bit.ly/qzEwc6 Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in a minute!
