The field of quantum mechanics all fundamental forces are carried by particles. For instance, light is made up of massless particles called photons that carry the electromagnetic force. Likewise, the graviton is the theoretical particle that would carry the force of gravity. Scientists have yet to detect gravitons, which are tricky to find because they interact so weakly with matter.
