    "goal": "Detect antimatter galaxies, antimatter cosmic rays, antimatter asteroids, and invisible terrestrial entities by imaging negative-index (antimatter) light.",
    "problem_addressed": "Conventional convex-lens telescopes cannot focus or detect antimatter-light because it has a negative index of refraction; such phenomena appear invisible to the human eye and standard optics.",
    "concept_summary": "The Santilli Telescope uses a concave optical lens designed for a negative index of refraction to focus \"antimatter-light\". Images are captured with digital or film cameras; antimatter-light produces streaks or dots of darkness in long-exposure photographs, whereas ordinary matter-light produces bright streaks. By comparing paired images from a standard Galileo (convex-lens) telescope and a Santilli (concave-lens) telescope, unique darkness patterns are interpreted as evidence of antimatter phenomena or invisible terrestrial entities.",
