AS网站目录（www.adminso.com）：数学家：我们的宇宙是由计算机模拟而来

数学知识不同于其它知识，它的真理是客观的、不能否定的和永恒的。伟大的逻辑学家哥德尔认为，数学概念和理念形成了一个它们自己的客观现实，这个客观现实我们无法创造或改变，只能感知和描述。如果这是真的，我们是否生活在一个基于数学规律的计算机模拟中？

加州伯克利的数学教授Edward Frenkel指出，根据一个充满幻想的理论，高度发达的未来的某些计算机程序员设计了这个模拟，而身处其中的我们并不知道模拟的存在，我们所发现的数学真理不过是程序员使用的代码特征。

你可能不怎么相信这个理论。但牛津大学的哲学家Nick Bostrom根据逻辑推理辩解说，我们确实更有可能生活在一个模拟而不是一个真实世界之中。因为如果模拟是可能的，那么人类最终会创造出的模拟，不是一个而是很多个。随着时间的推移，模拟将会越来越多。最终，从统计学上说，我们最有可能生活在一个模拟世界里。

但如何用实证检验这一假说？物理学家Silas R.Beane教授和同事在预印本网站上发表了一篇论文，提出了一种检验世界是真实还是模拟的可能方法：用三维网格建模宇宙的一小部分，然后运行程序看会发生什么。

他们发现，计算机模拟产生了微小但可区分的异常――某种不对称性。也就是说，我们也许能在我们的宇宙中观察到相同的可区分异常，比如仔细分析宇宙射线，可能会揭示类似的不对称性――这将表明，我们可能是生活在别人的计算机模拟里。

怎么听起来像是黑客帝国的感觉...
