玻尔兹曼胸像,上方是熵的定义

玻尔兹曼大脑是假想的产生于混乱中熵的涨落的自我意识。自我意识是一种低熵态。奥地利物理学家路德维希·玻尔兹曼曾提出一个观点:如果已知的低熵态宇宙是来源于熵的涨落,那涨落中也应该会出现许多低熵的自我意识,比如一个孤单的大脑。这种孤单的大脑就被命名为玻尔兹曼大脑

A bust of Ludwig Boltzmann, for whom Boltzmann brains are named

A Boltzmann brain is a hypothesized self aware entity which arises due to random fluctuations out of a state of chaos. The idea is named for the physicist Ludwig Boltzmann (1844–1906), who advanced an idea that the Universe is observed to be in a highly improbable non-equilibrium state because only when such states randomly occur can brains exist to be aware of the Universe. The term for this idea was then coined in 2004 by Andreas Albrecht and Lorenzo Sorbo.
