没有一个统一的理论
No single unification theory of everything
摘要:
根据哥德尔的数学不确定性结果(不完全定理),量子不确定性表明物理学和宇宙在本质上可能是不确定的、不完全的和开放的,因此不需要单一的万物统一理论。宇宙是动态的,基本的物理模型和时空也是动态的。在早期宇宙中,随着四维时空一个维度一个维度地演化,一致但不同的模型一个接一个地出现,其中包含不同的粒子和相互作用。通过对超对称性、镜像对称性和动态相变机制--自发对称性破缺的新认识,提出了一套新的第一性原理来建立这类模型。在这个框架下,我们证明了没有万物理论的不同模型在宇宙的不同阶段或场景中以分层但一致的方式运行。特别是,时间箭头被自然地解释,物理学的标准模型被优雅地扩展到宇宙的时间零点。
英文摘要:
In light of Gödel's undecidability results (incomplete theorems) for math, quantum indeterminism indicates that physics and the Universe may be indeterministic, incomplete, and open in nature, and therefore demand no single unification theory of everything. The Universe is dynamic and so are the underlying physical models and spacetime. As the 4-d spacetime evolves dimension by dimension in the early universe, consistent yet different models emerge one by one with different sets of particles and interactions. A new set of first principles are proposed for building such models with new understanding of supersymmetry, mirror symmetry, and the dynamic phase transition mechanism - spontaneous symmetry breaking. Under this framework, we demonstrate that different models with no theory of everything operate in a hierarchical yet consistent way at different phases or scenarios of the Universe. In particular, the arrow of time is naturally explained and the Standard Model of physics is elegantly extended to time zero of the Universe.
