(from the article) > The reason we will not run out is that hydrogen forms bonds with other atoms besides itself And hydrogen is the single most common element in the universe (three times the Helium quantity, by mass despite being the lightest, according to [1]). Oxygen is the third one, and is 24 times less common than helium. No wonder our gas giants (and sun) are so big. Still according to [1], > Hydrogen and helium are estimated to make up roughly 74% and 24% of all baryonic matter in the universe respectively.
