Unlike other objects, the speed of light is always constant regardless of an observer's reference frame.

与其他物体不同，无论观察者的参考系如何，光速始终是恒定的。

But when Stella changed her direction for the return journey, she entered a different reference frame from the one she'd started in.

但当史黛拉改变方向返程时，的参考系与开始时的参考系不同。

Excuse me. If you were riding on the olive, you'd be in a non - inertial reference frame and would...Are you okay?

抱歉，如果你在那颗橄榄上，你就是一个非惯性参照系并会… … 你没事吧？

Hey, I wasn't speeding—in my inertial reference frame.

嘿，我没有超速——在我的惯性参考系中。

'Down' is an illusion of your reference frame.

“下”是你的参考系产生的幻觉。

To  earth's reference frame, gravity just pulls in.

以地球的参考系而言，重力只是向下拉。

And you can't really define a reference frame for photons as we just did.

你不能真的像我们刚才那样为光子定义一个参考框架。

And where does reference frames fit in?

参考系又扮演什么角色呢？

So again, a reference frame, I mentioned earlier about the model of a house.

再次提到，参考框架，我之前提到过关于房子的模型。

Well, what  Einstein showed with special relativity is that they're both correct…  in their own  reference frames.

嗯，爱因斯坦通过狭义相对论证明，这两种说法在各自的参考系中都是正确的。

Do not just start regurgitating frame of reference, frame of reference, and assume that you're suddenly healed.

不要只是开始机械地重复“参照框架”、“参照框架” ， 就以为自己突然就好了。

The first says that the laws of physics are the same in all inertial reference frames.

第一个说物理定律在所有惯性参考系中都是相同的。

We do this by using units and frames of reference, which are also called reference frames.

我们通过使用单位和参考系（也称为参考系）来做到这一点。

From different reference frames moving relative to one another, there can  never be agreement on the simultaneity of events.

从相互运动的各个参照系来看，事件的同时性永远无法达成一致。

Well, we state the reference frame we're using.

好吧，我们声明我们正在使用的参考系。

This reference frame is not an inertial reference frame.

这个参考系不是惯性参考系。

You know, you can have two events that happen and two different people looking at it from two different what we call reference frames.

可以有两个事件发生两个不同的人身上、他们从两个不同的参照系来观察它。

Again, this is not an inertial reference frame, therefore, Newton's First Law does not hold true in this reference frame.

再者， 这不是一个惯性参考系，因此， 牛顿第一定律在这个参考系中不成立。
