ELI5: Why, when you swat a fly mid-flight, it seems unfazed and keeps flying? If an airplane got smacked by a giant hand while flying the plane would be destroyed wouldn’t it?

The square/cube law means that bigger things are weaker than small things. Something 10 times longer, wider and higher will be 100 times stronger but it will weigh 1000 times more. That means it will be 10 times worse at supporting its own weight. That’s why fleas can jump massively high but elephants can’t jump at all. And when you’re as big as a planet, you can’t support your own weight at all and the only shape you can be is a sphere.
