Quantum fields are rippling substances that suffuse space. A ripple in a quantum field is a particle. By exchanging streams of these particle-ripples, one object can push or pull on another, exerting a force. The electromagnetic force, for instance, is conveyed through disturbances in the electromagnetic field that we call photons.
