循环宇宙
The cyclic universe
摘要：
循环宇宙模型是对爆炸宇宙模型和烟火宇宙模型的修正。循环宇宙经历了六个转变：三重态宇宙、暴胀、大爆炸、精粹、大挤压和紧缩转变。宇宙从11维时空开始，有两个边界9-膜，它们被一个有限的间隙隔开，跨越一个中间的大体积。三重态跃迁开始于体9-膜从隐藏的边界9-膜产生，并与可预见的9-膜碰撞。碰撞开始了暴胀过渡。碰撞是预可观测9-膜和体9-膜之间的膜维干涉混合。结果是混合膜（组合膜维度），内部空间（取消膜维度），体空间，3-膜真空和宇宙辐射。宇宙膨胀过程中产生的宇宙辐射导致了大爆炸。与此同时，隐藏膜经历逐步的分解，逐步从9-膜变成3-膜。可观测的宇宙以恒定的速率膨胀，直到本质跃迁。之后，有大挤压过渡（大爆炸的逆转）和通货紧缩（通货膨胀的逆转）。分裂和浓缩的宇宙循环再次开始。所有基本粒子和强子的质量都可以计算出来。
英文摘要：
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.
