Cosmic Eye allows to user to zoom in and out of a preset image, by enormous zoom factors, reaching down the smallest known sub-atomic particles and up to the entire observable universe. Where possible, the app displays real photographs obtained with modern objectives, telescopes, and microscopes. Other views are phenomenal renderings of state-of-the-art computer models. This app draws inspiration from a progression of increasingly accurate graphical representations of the scales of our Universe, including the classical movie “Powers of Ten” (1977), directed by Charles and Ray Eames.
