We show a chiral symmetry conservation principle based on chemical kinetics using stochastic results. Suppose the chiral symmetry conservation is evoked, and our universe can be considered globally asymmetric. In that case, there are at least two mirrored asymmetric universes if all the chiral properties are strongly correlated. However, if the chiral correlations are weak or nonexistent, there are possibly Many-(Chiral-Symmetry)-Worlds. Alternatively, if our universe is only locally asymmetric, there could be a single universe with segregated chiral regions. The possible mechanisms of the primordial chiral symmetry breaking can only be found if the chiral symmetry is not truly conserved by assuming the initial racemic conditions. In that case, our universe is asymmetric and could be alone. On the other hand, if the chiral symmetry is conserved, there is no chance of finding the primordial chiral symmetry breaking. Based on this conservation (or not), it is possible to infer two opposite hypotheses, where two general scenarios about the chiral universes are possible.
我们使用随机结果展示了基于化学动力学的手性对称守恒原理。假设手性对称守恒被激发,并且我们的宇宙可以被视为整体不对称。在这种情况下,如果所有的手性性质都强烈相关,那么至少有两个镜像不对称的宇宙。然而,如果手性相关性较弱或不存在,则可能存在许多(手性对称)世界。或者,如果我们的宇宙只是局部不对称,那么可能只有一个具有分隔的手性区域的宇宙。只有在手性对称性没有真正被保留的情况下,通过假设初始外消旋条件,才能找到原始手性对称破缺的可能机制。在这种情况下,我们的宇宙是不对称的,可能是孤独的。另一方面,如果手性对称守恒,就没有机会找到原始手性对称破缺。基于这种守恒(或不守恒),可以推断出两种相反的假设,关于手性宇宙存在两种可能的一般情况。
