And we have to go beyond four dimensions to perhaps, let's say, 10,11 dimensions.

我们必须超越四个维度，可能要到达，比方说10，11 个维度。

The way light travels through the four dimensions of space-time is mathematically akin to how it moves through “metamaterial”.

从数学的角度看，光穿越四维空间的方式与它穿透“超材料”的方式很接近。

There are four dimensions of our mind.

我们的思想有四个维度。

How do you do that in four dimensions?

你如何在四个维度上做到这一点？

What we now call Euclidean space-time is very similar except that it has four dimensions instead of two.

我们现在所说的欧几里德时空非常相似，只是它有四个维度而不是两个维度。

Time is one of the four dimensions in the universe, along with three dimensions of space.

时间是宇宙中的四个维度之一，还有空间的三个维度。

We wouldn't see these extra dimensions, because light wouldn't propagate through them, but only through the four dimensions of our universe.

我们看不到这些额外的维度 因为光不能穿过它们 只能穿过宇宙的四维空间。

Indeed, moving beyond four dimensions in this way would also allow physicists to try to integrate Einstein's work with quantum theory, the other great breakthrough of 20th-century physics, but one which simply refuses to overlap with relativity.

这样超越四维的运动确实还可能让物理学家们试着将爱因斯坦的理论与量子论结合起来，量子论是20世纪物理学的另一重大突破，但是量子论与相对论难有交集。
