The distance between the nodes is called the Planck distance which in the Q-FFF model is variable.
In special cases like around all Black Holes the Planck distance is decreasing and the light is bending (the origin of Gravity lensing) by the vacuum string attraction and consumption.
Quantum String Gravity according to Q-FFF Theory.
Each massive fermion object seems to be able to transform individual Axion vacuum particles coming in from the outside vacuum frame by real collision, into less massive Gravitons, travelling with the local speed of light away from the object.
All massive objects emit a gravity pressure field of gravitons combined with a decreased number of vacuum Axions left over after fermion collision.
The outside oscillating vacuum field pointing towards the massive object is in competition with the pressure of the out going Graviton-Axion field to form the DUAL PRESSURIZED VECTOR gravity field result.
This field result can be represented by butterfly shaped gravity vectors in cross section. ( image: The dual pressure = attraction of the combined Higgs Axion Graviton Field).
