However my addition is, that those particles change real string form (and pressure) by the passage of a mass or a magnet or a charge and keeping the local spacetime lightspeed after leaving the object.
Reason to suggest that all forces in nature (even attraction and rotation) are compound pressure processes on fermions from all directions.

However, the consequence seems to be that black holes only feel the vacuum pressure and are growing by eating the vacuum. without anti gravitons.
