The movie Ant-Man explains that Pym Particles work by squeezing the space between atoms, letting someone shrink in size without losing any weight or density. This means a shrunken person, like Scott Lang, could still hit with the force of a normal-sized person. However, the movie immediately creates a problem when Hank Pym pulls a tiny tank from a keychain. If the tank kept its full weight, it would be impossible to carry, creating a plot hole. This issue gets even bigger in Ant-Man and the Wasp, where an entire laboratory building is shrunk down to luggage size and rolled through the city. According to the rules established in the first movie, that building would still weigh hundreds of tons! Luckily, a new book called Marvel Anatomy: A Scientific Study of the Superhuman offers a way to explain these inconsistencies and make everything fit together.
