GravyLensing

GravyLensing brings gravitational lensing, the cosmic phenomenon where space-time bends around massive objects, into your hands. ESA's Euclid mission is mapping this effect across billions of galaxies to reveal the dark universe. Now you can explore that same physics yourself. Point your camera anywhere and watch space-time bend like light passing through a galaxy cluster. Built on the same Singular Isothermal Ellipsoid (SIE) models astronomers use, every lens is a real galaxy cluster observed by Hubble, JWST, and Euclid, faithfully recreated on your device. Features • Apply scientifically accurate gravitational lensing to your live camera feed, photos, or videos • Browse a gallery of real galaxy clusters, each with their own unique lensing signature • Touch and drag to position the lens exactly where you want it • Adjust distance to sweep from subtle warping to extreme Einstein rings • Record warped video or capture still images and save them to your photo library Inspired by ESA's Euclid mission to map the dark universe, GravyLensing puts the physics of warped spacetime in your pocket. No ads. No data collection. Just physics.
