本文考虑一种势包含一个以上稳定或亚稳最小值的场论。结果表明，如果真空能量大于零，引力效应使高能“假真空”的气泡有可能在低能“真真空”的均匀区域内成核和膨胀。“其结果是，在德西特或类德西特时空中，任何初始状态最终都会演变成所有可能真空的独特统计混合物。如果真空能量相对接近，则该统计混合物可以描述为在霍金温度下处于热平衡的子系统的集合。
A field theory whose potential contains more than one stable or metastable minimum is considered. It is shown that if the vacuum energies are greater than zero gravitational effects make it possible for bubbles of a higher-energy ''false vacuum'' to nucleate and expand within a homogeneous region of a lower-energy ''true vacuum.'' A consequence of this is that in a de Sitter or de Sitter-like space-time any initial state will eventually evolve to a unique statistical mixture of all possible vacua. If the vacuum energies are relatively close, this statistical mixture can be described as a collection of subsystems in thermal equilibrium at the Hawking temperature.
