Final answer:
The Higgs field is a theoretical field that permeates the entire universe and gives particles mass. As particles pass through the Higgs field, they experience resistance and their motion slows down, resulting in them gaining mass.
Step-by-step explanation:
The Higgs field is a theoretical field that permeates the entire universe. It is responsible for giving particles mass. According to the theory, particles interact with the Higgs field and acquire mass as they pass through it. Think of it like swimming through a pool of water: as the particles move through the Higgs field, they experience resistance and their motion slows down, resulting in them gaining mass.
