Swimming underwater = flying because you are not affected by gravity

Prove me wrong

Noone even proving me wrong tho

OP is correct in the sense of general relativity. On the other hand, you don't need water for that, a simple jump down from a wall does the trick as well.

holy fuck...that gif is scary as hell. Isn't the swimmer scared there might be some sea monster down there? It's so dark down there, jesus...

impossible. there's some gravitational effect on objects in a pool of water regardless of the material/composition.

His direction of movement, even given his jump upwards (and the fact the fact that he is walking), has a net direction of down. Gravity is pulling him down - he is not resisting gravity such that he maintains horizontal direction in a horizontal plane, therefore he is not flying he is falling. Furthermore, the term "flying" is strictly applied to movement through air (earths atmosphere), not to movement through a liquid medium. Thus he is swimming at some points and descending in free fall at others.
