Since its inception, the Marvel Cinematic Universe has been tasked with adapting six decades of comic book continuity into a format that functions as standalone entertainment. That process inevitably leads to changes, as the reduced screen time of movies and TV shows, added to the shifting tastes of mainstream audiences, means the MCU can only work if it streamlines backstories, changes power sets, and even merges multiple characters into a single entity. That doesn’t mean the MCU is perfectly consistent, though, as even Marvel Studios’ best efforts resulted in some glaring plot holes, like the functioning of the Pym Particles. Since Ant-Man arrived in theaters in 2015, the particle-based technology piloted by Scott Lang (Paul Rudd) has operated under a set of rules that contradict themselves depending on what the story requires, a specific problem inherited from the comic books.

The core explanation offered in Ant-Man posts that the Pym Particles compress the space between atoms, allowing the user to shrink while retaining full mass and density. That means a shrunken Scott Lang can deliver a punch with the force of a full-grown man. However, the contradiction appears immediately in the same film when Hank Pym (Michael Douglas) produces a miniaturized tank from a keychain. A military tank weighing dozens of tons, reduced to keychain dimensions, would be physically impossible to carry in a pocket if it retained its mass, creating a plot hole. The problem compounds in Ant-Man and the Wasp, where Pym shrinks an entire laboratory building to the size of portable luggage and wheels it through city streets. Under the mass-preservation rules that the first film established, that structure would still weigh hundreds of tons. Fortunately, the new book Marvel Anatomy: A Scientific Study of the Superhuman offers a consistent framework to explain these contradictions.
The Marvel Anatomy Book Tries to Explain How Pym Particles Work
Marvel Anatomy: A Scientific Study of the Superhuman, written by Marc Sumerak and Daniel Wallace for Insight Editions, approaches the Pym Particle problem through Galileo’s square-cube law. The law establishes that as an object increases in size, its surface area grows quadratically while its volume, and therefore its mass, grows cubically. Applied to Scott Lang, scaling up ten times his standard height would make him one thousand times heavier, a physical condition that would render movement impossible. The book argues that the particles resolve this by dynamically adjusting the user’s mass to whatever functional level the situation demands rather than locking it to a fixed value. That conceptual shift, applied retroactively to the MCU’s established canon, can resolve the tank keychain contradiction because instead of preserving particles, they merely manage it, reducing it to a portable level when transport was required and restoring it when force was needed.
The book credits the three-axis theory to Scott Lang himself, framing it as his own working hypothesis rather than confirmed physics. According to the text, Pym Particles operate across three simultaneous axes, with size, strength, and durability each functioning as an independent variable that can be calibrated separately. A shrunken Scott Lang can deliver a blow with the force of a full-grown adult because the strength axis was never reduced in proportion to the size axis. While that’s all pseudoscience, at best, the book functions as an internally consistent model that accounts for every anomalous Pym Particle moment across decades of Marvel Comics publication and the entirety of the MCU.
Marvel Anatomy: A Scientific Study of the Superhuman by Marc Sumerak and Daniel Wallace is available now from Insight Editions.
