Is it possible to create a universe in the laboratory?

至于“在实验室里创造宇宙是可能的吗？”由Farhi&Guth(1987)提出，我们发现了两个理论模型，其中一个(准)稳定粒子通过一个没有初奇性的经典过程转变为一个膨胀宇宙。一种是稳定的磁单极子演化成膨胀宇宙的模型，另一种是呼吸假真空气泡演化成膨胀宇宙的模型。作为粒子场中孤子解的基础性研究，我们用突变理论建立了一种新的稳定性分析方法。

As to the question "Is it possible to create a universe in the laboratory?" posed by Farhi & Guth (1987), we have found two theoretical models where a (quasi) stable particle changes into an inflationary universe by a classical process without initial singularity. One is a model where a stable magnetic monopole evolves into an inflationary universe, and the other is a model where a breathing false-vacuum bubble does. As a fundamental study of soliton solutions in particle fields, we have formulated an new method of stability analysis by use of catastrophe theory.
