时间之箭与生命的起源

Time's arrow and life's origin

Lucas Johns

摘要:

热力学时间箭头的问题被认为是解决的观察,我们的宇宙最初是--仍然是--远离平衡。心理上的时间箭头问题通常被归因于相同的解决方案,但这种联系尚未完全建立。我认为,一个令人信服的解释心理箭头需要了解的物理条件,必要的生命出现从一个生命前的环境。一个简单的计算说明了来自太阳和地球内部的维持生命的能量通量如何使生命的发展偏向宇宙初始条件所继承的箭头方向。

英文摘要:

The thermodynamic arrow-of-time problem is thought to be resolved by the observation that our universe initially was---and still is---far from equilibrium. The psychological arrow-of-time problem is often attributed the same resolution, but the connection has not been thoroughly established. I argue that a compelling explanation of the psychological arrow requires an understanding of the physical conditions necessary for life to emerge from a prebiotic environment. A simple calculation illustrates how life-sustaining energy fluxes from the Sun and the Earth's interior bias the development of life in the direction of the arrow inherited from cosmic initial conditions.
