Gravity acts like quantum entanglement when an object travels close to FTL, meaning an object encounters infinite gravitional forces no matter where the object is trying access FTL. Separating the higgs boson from particles around an object traveling FTL allows the object to access less mass space, or Primordial space where mass does exist but not as much. Once the object passes through Einstein Space, the constant introduction of higgs into Enstein Space will seal the rift due to the particles stripped of mass having mass instantly re-introduced.
When the object travels FTL, the object will still encounter gravitational forces that will add enough mass to the ship to keep the ship from flying apart due to the ship encountering negative mass that is only possible by crossing into the Primordial universe that came before Einsteins universe.
Negative mass is what the objects in a dream are created from. In the real world, the some objects are made from ass. But in the dream the objects are considered negative mass because you could never fit the same Pinto with inside of someones head. Nor can an object ever exist without mass. But objects in a dream do exist without mass.
Simply design a device based on how the eye ball works but strips away the mass from particles and the distance covered will be the aame distance travelled by the ship relative to seeing the person in real life based on how small the person appears in the dream.
Although the length of the eye and brain is small, when the perspectiive value of the height of the object in the dream is compared to object with mass, the distance between the object with mass and object without mass in the dream in possibly a few light years in distance.
