The term "dual graviton" is not widely used or recognized in conventional physics literature. However, it could refer to concepts that arise in certain advanced theories in theoretical physics, particularly in the context of quantum gravity and string theory. In general, a graviton is a hypothetical elementary particle that mediates the force of gravitation in quantum field theory, analogous to how photons mediate the electromagnetic force. Gravitons are expected to be massless and have a spin of 2.
