  The cyclic universe model is a modification of the ekpyrotic universe and the
pyrotechnic universe models. The cyclic universe goes through the six
transitions: the triplet universe, the inflation, the big bang, the
quintessence, the big crush, and the deflation transitions. The universe starts
with eleven dimensional space-time with two boundary 9-branes separated by a
finite gap spanning an intervening bulk volume. The triplet transition starts
when the bulk 9-brane is generated from the hidden boundary 9-brane, and
collides with the pre-observable 9-brane. The collision starts the inflation
transition. The collision is the brane dimensional interference mixing between
the pre-observable 9-brane and the bulk 9-brane. The results are the mixed
branes (combined brane dimensions), the internal space (cancelled brane
dimensions), the bulk space, 3-brane vacuum, and cosmic radiation. Cosmic
radiation generated during the inflation leads to the big bang. Meanwhile, the
hidden brane undergoes stepwise fractionalization, changing in stepwise manner
from 9-brane to 3-brane. The observable universe expands in a constant rate
until the quintessence transition. Afterward, there are the big crush
transition (the reverse of the big bang) and the deflation (the reverse of the
inflation). The cosmic cycle of the fractionalization and condensation starts
over again. The masses of all elementary particles and hadrons can be
calculated.
