On Super Bowl Sunday, Olympic gold medalist Simone Biles posted a photo of herself standing with Shaquille O’Neal, and social media users couldn’t wrap their heads around their extreme heights.

Biles is around 4 feet 8 inches tall, while the former NBA star is 7 feet 1 inch tall. When they stand next to each other, you can really see the difference.
