As the ultimate building blocks of the universe, the limit structureless quark
u∞ and its anti-quark
are considered at the infinite sublayer level of the quark model. Then
CP is violated in the doublet of
u∞ and
u∞CP quarks to account for the asymmetry of the number of particles and anti-particles. This
CP violation is explained by a
SU(2) noncommutative geometry. The second, third and fourth generation quarks are considered only as the excited states of the first generation
u∞ and
u∞CP quarks. The fourth generation quarks are derived from both
CPT transformation and the
SU(2)
L×
U(1) gauge theory. The dark matter, quarks, leptons, gauge bosons and Higgs bosons are composed of only the
u∞ and
u∞CP quarks and the cosmological constant in Einstein’s field equation is also derived from the Higgs potential. Thus, the limit particle
u∞ and its anti-particle
u∞CP are the ultimate particles of the universe and produced thermally in the hot early universe of the Big Bang.
