It’s called gravity genius. And that link is about the atmosphere being dragged by the earths rotation (no-slip boundary layer fluid dynamics), nothing to do with the force of gravity overcoming the other forces acting on particles of gas which make up the atmosphere (thus “holding in” the atmosphere without some kind of firmament or whatever it is you’re suggesting here). Two different concepts.
