One idea is that as a simulation runs, it might accumulate errors over time.

一个想法是，随着模拟的进行，随着时间的推移，错误可能会被积累。

He says the history of humanity could be an ancestral simulation run by a post-human species.

他说，人类的历史可能是后人类物种的祖先模拟。

Those computer simulations run decades ago turned out largely to be correct and so everyone involved should be congratulated.

几十年前运行的计算机模拟被证明在很大程度上是正确的，因此应该祝贺每个参与者。

Once you set an initial state of living squares and let the simulation run These simple laws determine what happens in the future.

一旦设定活方格的起始状态 并开始启动模拟这些简单的规则就会决定未来发生什么事。

Now, if we try to simulate this effect with traditional techniques on a coarse grid, we'll encounter a weird phenomenon: namely, the longer our simulation runs, the larger the volume of the sand becomes.

现在，如果我们尝试用传统方法在粗糙的网格上模拟这个效果，我们将会遇到一个奇怪现象：模拟的时间越长，沙子的体积就会变得越大。
