The Black Scientist meme, commonly known by the caption 'Finally Xium,' features a stock photo of a man in a lab coat intensely examining a test tube filled with colored liquid. The humor stems from the character announcing the discovery of an impossible or nonsensical element by adding the suffix '-ium' to everyday objects or concepts, such as 'Finally, Water-ium' or 'Finally, Obamium.' The format went viral on Reddit and Twitter in early 2020, evolving into a versatile template for parodying scientific breakthroughs and the excitement of finding something that logically shouldn't exist.
