This paper proposes that all
Bosons and all
Fermions originate from even more elementary constituents, which called Spin
Angular Momentum Vacuum (
SAMV).
SAMV is filled with Primitive Spin Particles
(
PSP). The total square spin angular momentum of each
PSP is negative, less
than zero. Those
PSP labeled by index
of Casimir Operator, are called
Vacuum Spin Particle (
VSP), which could be contracted into so-called Vacuum
Bubbles (
VB).
VB are
identical bubbles, are "sub-observable physical
quantities".
VB are paired up into Vacuum Bubble Pair
VBP.
VSP ω
j(or ω
+,ω-) results from
Self-identical vacuum bubble interaction through the zero order Phase
Transition PT. When the 1st, 2nd, 3rd,... order PT of VBP occur, then VBP turn into Bosons and Fermions, excited out of sea level of SAMV ocean.
