TED Talksさんのインスタグラム写真 - (TED TalksInstagram)「You may have seen that black hole photo all over the internet this week, but here’s why it’s such a big deal: until now, the existence of black holes was only inferred from the movements of other objects, such as stars and light. For the first time ever, we now have visual proof of one! Capturing this image required an international team of scientists, a virtual Earth-sized telescope (yes, really), and an algorithm created by imaging scientist Katie Bouman, among others. This wasn’t just any algorithm, though — it was an algorithm that could piece together each tiny measurement of light radiating from the black hole, captured by the component radio telescopes as the Earth spins. The image shown here is a construction of that algorithm using simulated data, since Katie gave her TED Talk before the official black hole image was released. Katie began this project without any background in astrophysics, and she’s proof that we need people from all disciplines working together to achieve the impossible. “I’d like to encourage all of you to go out and help push the boundaries of science, even if it may at first seem as mysterious to you as a black hole,” she says.
