"Locate the Milky Way's Monster Black Hole with This iPhone App"

A new iPhone app called Galactic Compass, developed by Matthew Webb, uses ChatGPT to point users in the direction of the Galactic Center, where the supermassive black hole Sagittarius A* resides. The app utilizes complex calculations and quaternions to locate the Galactic Center in relation to the user's date and location, and the 3D arrow on the app rotates in real-time in response to the device's orientation. Webb's collaboration with ChatGPT allowed him to build the app despite having limited app-building experience, making it easier for anyone with an iPhone to locate the center of the Milky Way.
