There is currently no established theory or evidence that directly relates the mass of the electron to the relative mass of the graviton.
The electron is a subatomic particle with a known mass, and it plays a fundamental role in the structure of atoms and the behavior of matter. On the other hand, the graviton is a hypothetical particle that is believed to be the carrier of the gravitational force in theories that attempt to reconcile quantum mechanics with gravity, such as string theory. However, the graviton has not been directly detected or confirmed experimentally.
The relationship between the mass of the electron and the mass of the graviton, if it exists, would be determined by a more comprehensive theory that successfully combines quantum mechanics and gravity. As of now, such a theory remains elusive, and the properties of the graviton, including its mass, are still the subject of theoretical research and investigation.
Therefore, it is not currently established that the mass of the electron and the relative mass of the graviton are directly related.
