Pym Particles

Pym Particles are a fictional concept from the Marvel universe, specifically associated with the character Ant-Man. They are hypothetical subatomic particles that can alter the size and mass of objects or beings. When tiny Pym Particles are used, they allow objects or people to shrink down to microscopic sizes or grow back to normal size, while maintaining their original mass and strength. This allows characters to navigate different environments easily, shrinking to avoid detection or growing to giant sizes to increase strength. Essentially, Pym Particles enable controlled and reversible size manipulation at a quantum level.
