How is only in one direction found, a mass effect? Q-FFF Theory says that the origine lies in the internal direction of the neutral charged oscillating Graviton Gluon photon , or anti- Graviton Gluon , oscillating between positive charged Quarks, indeed leaving the atom as anti gravity radiation.
see below: the Q-FFF alternative standard model below. with the origin of gravity created by the 2 combined vector pressure result between Axinon vacuum pressure and the less strong pressure of mass created weak atomic graviton pressure. like the earth (quasi-) graviton pressure.
So, we are pushed to the earth from above. by the combined pressure effect between weak gravitons from below and stronger pressure from Axion vacuum particles from above.. so gravions must have different shape than the vacuum Axion particle, to create real pressure effect force in the collision between them..
Below:A quasiparticle gluon that only has mass effects, when moving in one direction. and able to leave the quark over only a small working distant for collision with fermions. .see experiments.
Examples of quasiparticles: polaron: A moving electron that interacts with surrounding atoms in a way that shields its charge with a cloud of polarisation.
Exciton: An electron bound to a 'gap' in charge known as an electron hole.
Majorana fermion: A neutrally charged quasiparticle that's considered a particle and its own antiparticle at the same time.
Phonon: The quantum equivalent of a sound wave, or a vibration through atoms in a neat, crystal arrangement.
