String Theory with Oscillating Space-Time Dimension Number

In 
conventional string theory with fixed space-time dimension number, the extra 
space dimensions are compactized. In string theory with oscillating space-time 
dimension number, dimension number oscillates between 11D and 10D and between 
10D and 4D reversibly, and there is no compactization. Dimension number 
decreases with decreasing speed of light and increasing rest mass. The 4D 
particle has the lowest speed of light and the highest rest mass. The two 
different oscillations between 10D and 4D are the stepwise oscillation passing 
through every dimension number and the direct oscillation oscillating directly 
between 10D and 4D without the intermediate dimension numbers. Dark energy 
represents the stepwise oscillation, and dark energy becomes observable only 
when it has 4D space-time. 4D baryonic 
matter and 4D dark matter represent the direct oscillation directly from 10D to 
4D. Our universe is the dual cyclic universe of the dark energy universe and 
the baryonic-dark matter universe. The Big Bang in the baryonicdark 
matter universe produced irreversible kinetic energy that stopped the 
reversible direct oscillation. The reversible direct oscillation will resume 
after the Big Crush to remove irreversible kinetic energy. Our cyclic universe 
started from the zero-energy universe through the four-stage transformation. The 
theoretical calculated percentages of dark energy, dark matter, and baryonic 
matter are 68.3, 26.4, and 5.3, respectively, in agreement with observed 68.3, 
26.8, and 4.9, respectively. According to the calculation, dark energy started 
in 4.28 billion years ago in agreement with the observed 4.71 ± 0.98 billion 
years ago.
