The Biefeld-Brown “vector”, or B-B vector, is a simple indicator in the Biefeld-Brown effect.
It might also have a physical interpretation related to the inhomogeneous charge density distribution in the capacitor’s dielectric. It points in the same direction as electric dipole moment ( electric dipole moment propulsion ; electric dipole spacecraft ).
This “vector” inside the charged asymmetric capacitor always points in the direction from the negative to positive plate.
For example, an atom can be conceptualized as a spherical asymmetric capacitor:
In the case of an atom of ordinary matter, its negative plate is larger, so the B-B vector is said to be “down” (towards nucleus), indicating attractive gravity.
But the in case of an antiatom of antimatter, its B-B vector is “up” (away from nucleus), indicating repulsive gravity (i.e. antigravity).
All atoms composing Earth have their B-B vectors “down”, and atoms composing material bodies on Earth also have their B-B vectors “down”, therefore Earth will attract these material bodies, and material bodies will attract Earth — an attractive gravitational interaction.
On the quantum-scale, Earth and material bodies on Earth are composed of many “capacitors” (atoms) that have their Biefeld-Brown vectors “down”, while at the same time on the macro-scale, Earth is just one big planet-size capacitor that has its Biefeld-Brown vector “up”, meaning directed away from its “nucleus”, i.e. from the ground up towards the ionosphere.
