The basic idea behind QFT is that particles interact with each other by exchanging virtual particles, which are particles that are not directly observable but can be thought of as “messengers” that carry forces between particles. These virtual particles are described by fields that permeate space and time, and the interactions between particles can be calculated using these fields.
