Like, the nutrition facts table says it contains nothing other than some sodium. No sugars or fats or calories at all

Yet it clearly is edible, so what is it? Some concoction made mostly from indigestible minerals?

Aspartame has about the same amount of calories as sugar (4kcal per gram). But it's much more sweet so you need very little of it. So there is a very tiny amount of sweetener which does contain calories but it's rounded down to 0.

    The difference is also big enough that cans of diet coke float and regular sink.
