Idioms Memes

Regular folks: "The sky is the limit." Astronauts: *smugly side-eyes in 408 km orbital altitude* Technically, Earth's atmosphere extends about 10,000 km into space, gradually thinning until it merges with the solar wind. The Kármán line at 100 km is just an arbitrary boundary where aerodynamic lift becomes useless. Meanwhile, Voyager 1 is chilling 23 billion km away, basically flipping off our puny atmospheric "limits." Space exploration really puts our earthly idioms in their place!
