  The cosmic vacuum is the wavefunction of the eleven dimensional Planck
supermembrane. The Planck wavefunction is the superposition of dimensions from
eleven to four dimensional spacetime with decreasing energy and increasing
size. The cosmic vacuum is a gigantic cosmic particle-wave. It undergoes a
gigantic slow cosmic oscillation between the high-energy eleven dimensional
spacetime and the low-energy four dimensional spacetime. The origin of ordinary
(baryonic) matter in the big bang universe is the collapsed Planck wavefunction
due to the lepton-quark entangled state with two unequal sets of spacetime as
the quantum system-measurement entangled state in Hilbert space. The collapsed
Planck wavefunction has four dimensional spacetime and seven dimensional
internal space (non-spacetime) with seven gauge bosons. The remnants of the
cosmic oscillation are cosmic radiation, gravity, and microscopic particle-wave
in the four dimensional spacetime. Internal symmetries for gauge bosons,
leptons, quarks, and black holes are in the seven dimensional internal space.
The result is the big bang universe with the cosmic vacuum. The cosmic vacuum
has the four-to-eleven dimensional spacetime supersymmetry, while the big bang
universe has the four dimensional spacetime and the seven dimensional internal
space. The masses of elementary particles can be calculated with only four
known constants: the number of the extra spatial dimensions in the
supermembrane, the mass of electron, the mass of Z, and the fine structure
constant for the magnetic field.
