So what does he do actually? I know he shrinks, but here's my problem (mainly attributed to lack of knowledge): When he shrinks, does he lose atoms? If he does, does he retain the proportional strength of a man, therefore having strength in direct proportion to size? Does he maintain the same atom count? If he does, do they shrink in size as well? If they shrink in size, do their properties alter? Does space itself around him shrink as well? Either way, does he retain his density, and therefore maintain the strength of a normal man? Wouldn't he also weigh as much and crush the shoulders of men he stood on? I'm going to throw out the density/increased strength assumption based on this side effect which is counter-evidenced in comics. So, since he loses atoms when he shrinks, where do they go? Matter can not be created nor destroyed; but it can be converted to energy. So, does his mass turn into a gaseous substance? Does he release in incredibly exothermic reaction? How the hell does he stay alive!?
