What strategy did astronomers use to achieve the incredible resolving power necessary to successfully image the event horizon of the black hole in galaxy M87? Select one: O a. They built the world's largest infrared telescope in the high desert of Chile, which was able to achieve sensitivities greater than any telescope in history. ob. They linked together a global chain of radio telescopes, achieving the resolving power of a radio dish nearly the size of Earth c. They used a specially engineered metallic coating on the Hubble Space Telescope, allowing optical sensitivities never before imaginable. od. They inserted a new detector into the world's largest optical telescope, allowing for sensitive observations at wavelengths previously out of reach. e. They sent Matthew McConaughey and Anne Hathaway to venture through a wormhole and discover the secrets of gravity. Matt Damon almost ruined everything for humanity, but then TARS plunged into a massive black hole and transmitted the necessary data from inside the event horizon, and it was all good. Whew! (Thanks TARS, you're the best!)
