The emission of photon holes by the Earth would also tend to add photons filling even more photon holes in the Earth. Hence, if the Earth is made of photon holes, the Earth may slowly melt away. If, on the other hand, the Earth is made of ordinary positive energy matter, both the emission of photon holes by the Earth and the addition of photons from space would tend to add mass to the Earth over time. Since there is some evidence for the expansion of the Earth and the other planets, this may add weight to the notion that matter is NOT composed of photon holes, but only made of ordinary positive matter. To unify gravity with electromagnetic forces, it is important to see that the forces require both photons and photon holes.
Electromagnetic gravity is both a push from space and a pull toward a massive body.
It is, therefore, the electromagnetic field, a background of photons and photon holes, that is responsible for push-pull gravity. Acknowledgment I wish to thank Martin Holla for his contributions to this text concerning negative impulse gravitons. To This Text Are Appreciated.
