We propose using fuzzy axion dark matter to test the anthropic principle. A very light axion can be directly detectable, at least by black hole superradiance effects. The idea then is that gravitational and astrophysical observations can discover a light axion in the regime where it must be all of dark matter with abundance which must be set up by the anthropic principle, due to excessive primordial misalignment induced by inflation-induced Brownian drift of fluctuations. Yet it may turn out that dark matter is something else instead of this axion. Since the de Sitter-induced axion misalignment controlled only by the de Sitter curvature cannot be evaded, this would invalidate the anthropic prediction of the dark matter abundance.

我们建议使用模糊轴子暗物质来测试人类原理。非常轻的轴子可以直接检测到，至少可以通过黑洞超辐射效应来探测。因此，引力和天体物理观测可以在该状态中发现一个轻轴子，它必须是所有具有丰度的暗物质，这必须由人为原理建立，这是由于膨胀引起的布朗波动漂移引起的过度原始错位。然而，事实证明，暗物质是其他东西，而不是这个轴子。由于 de Sitter 诱导的轴子错位仅由 de Sitter 曲率控制是无法避免的，这将使人为对暗物质丰度的预测无效。
