Planetary Rounds
There are four (4) evolutionary rounds of three (3) Planetary Cycles totaling 12 dimensional timelines that comprise the particle and anti-particle Universe. The Ascension cycle is about accelerating through a gradual particle/antiparticle merge of these 12 timelines. Hence the importance of the 12 strand DNA; each strand corresponds to 1 dimension. 3 Planetary Cycles (4 rounds in each cycle) = 12 Dimensional Timelines.
