Expanding Hole

What: Stare at the black hole. Give it a few seconds. It’s growing, right? Like you’re falling in. It’s not, the image is totally still. It’s by Akiyoshi Kitaoka (pronounced key-TAH-oh-kah), and in 2022 some researchers showed it to 50 people and watched their eyes [1]. The wild part: your pupils fall for it too. They open up, like you’re heading somewhere dark. How To: Stare at the middle and let it build.
