We have discovered that we can get a much simpler set of equations for fundamental physics by supposing that what we ordinarily perceive as empty space is actually a medium. We have observed the effects of the “water” that we use to simplify our equations – it slows down particles, and makes them heavy – but we do not know what it is made out of.
我们就是那些鱼。我们发现，假定我们平常所认为的空间实际上是一种介质，就可以大大简化基本的物理学方程。我们观察到了“水”的效应 —— 它使物体运动减缓，增加了物体的重量等等，但我们还不知道它是由什么东西构成的。
