gravity is not cause by the motion of mass, it is not require to make gravitational attraction...anyway...bake to your model of the atom, i finally remembered an evidence that charges and poles act differently. It is written in Maxwell's equation that the a pole in magnetic field...
The real string theory consist of tiny 1-dimensional strands of energy called the string. This string has a size of about the Planck length. The vibration mode of this string is quantize and will not take form of a human just like u said.
Another thing i want to ask is what will this theory say about the bending of light rays...
since according to what i understand about your theory...this "graviton" of yours is just another form of photon....and photons by nature have a very small strength of interaction between themselves (fine...
yes...haha...i forgot to add it to the video....i had to make it in a hurry during that time...
