论文摘要
我们试图找到条件，其实现允许出生在一个可稳定的假真空状态下的宇宙生存而不崩溃。发现的条件是以$ t $ T $瞬时衰减率$ {\itγ}（t）$链接的不平等的形式。讨论了量子亚稳态状态的衰减速率的性质，然后分析和讨论发现条件的可能解决方案。在该模型中，认为表明，在亚稳态真空状态下出生的宇宙有很高的生存机会，直到很晚才能生存，如果生命周期，$τ_{0}^{f} $，它比通货膨胀过程的持续时间短得多。我们的分析表明，电动真空吸尘器的不稳定性不必导致宇宙的悲惨命运导致其死亡。
We try to find conditions, the fulfillment of which allows a universe born in a metastable false vacuum state to survive and not to collapse. The conditions found are in the form of inequalities linking the depending on time $t$ instantaneous decay rate ${\itΓ}(t)$ of the false vacuum state and the Hubble parameter $H(t)$. Properties of the decay rate of a quantum metastable states are discussed and then the possible solutions of the conditions found are analyzed and discussed. Within the model considered it is shown that a universe born in the metastable vacuum state has a very high chance of surviving until very late times if the lifetime, $τ_{0}^{F}$, of the metastable false vacuum state is much shorter, than the duration of the inflation process. Our analysis shows that the instability of the electroweak vacuum does not have to result in the tragic fate of our Universe leading to its death.
