通过计算由畴壁与无限真真空区域分隔的球对称假真空区域的动力学，研究了局部膨胀的可能性。对于一系列初始条件，假真空区域将经历通货膨胀。外部真真空区域的观察者会将系统描述为黑洞，而内部真真空区域的观察者会描述一个与原始时空完全脱节的封闭宇宙。我们认为这种机制很可能导致闵可夫斯基空间的不稳定：空间的一个区域可能会经历量子涨落进入假真空状态，演变成一个孤立的封闭宇宙；留在原来空间的黑洞会因量子蒸发而消失。这些孤立的封闭宇宙的形成也可能与黑洞形成过程中的信息丢失问题有关。
The possibility of localized inflation is investigated by calculating the dynamics of a spherically symmetric region of false vacuum which is separated by a domain wall from an infinite region of true vacuum. For a range of initial conditions, the false-vacuum region will undergo inflation. An observer in the exterior true-vacuum region will describe the system as a black hole, while an observer in the interior will describe a closed universe which completely disconnects from the original spacetime. We suggest that this mechanism is likely to lead to an instability of Minkowski space: a region of space might undergo a quantum fluctuation into the false-vacuum state, evolving into an isolated closed universe; the black hole which remains in the original space would disappear by quantum evaporation. The formation of these isolated closed universes may also be relevant to the question of information loss in black-hole formation.
