1. A quantizied gravitational wave........... 2. They travel at the speed of light 3. They have never been experimentally proven to exist. 4. They have been theoretically proven? 5. They permeate all dimensions. I have some ideas fixed in my head that need to be corrected. In another thread Nigel point out the scattering that would take place from photon interaction in such a bulk teaming with these theoretical massless particles. This is a fair statement. Yet from another perspective if any quantized version of the gravitational waves are considered, it can never represent the whole wave per say but represents part of the wave, meaning, each graviton would be describing differing values of that wave, so scattering would have been specific to each graviton? One thing that also materialize in this respect is the relationship to a holographical feature each graviton is describing? Please feel free to throw in pros and cons.
