Superfluid quantum space, Einstein’s principle of equivalence, and Bohr’s complementary principle

Einstein’s equivalence of inertial mass and gravitational mass is precisely measured. The common understanding is that inertial mass and gravitational mass are two different masses that are equal. Extension of the energy-mass equivalence principle on the superfluid quantum space is showing that inertial mass and gravitational mass of a given physical object have the same physical origin in the diminished energy density of superfluid quantum space in the centre of a given physical object. Particle motion in superfluid quantum space creates the wave of quantum space. Particles and waves are inseparable together.
