The Carl Sagan meme typically features the renowned astronomer and 'Cosmos' host, capturing his infectious enthusiasm for the universe. Most commonly associated with the catchphrase 'billions and billions'—a phrase he famously never actually uttered in that exact sequence on the show—the meme celebrates Sagan's legacy while poking fun at the sheer scale of the cosmos. Users often employ this template to describe massive quantities of anything, from internet data to personal regrets, or to add a touch of profound scientific wonder to everyday situations. It remains a staple for science enthusiasts and those who appreciate a bit of vintage educational aesthetic.
