TON 618 is known as one of the largest known ultramassive black holes, located in a distant quasar and often cited in astronomy videos for its staggering mass and scale. Online, its name became shorthand for something incomprehensibly huge, and creators began pairing facts about it with deep space audio to underline that size. The sound spread through space edits, comparison videos and meme posts about the universe, where a low drone signals that human scale no longer applies.
