Spoiler alert: the Universe is expanding, and it's this redshift that allowed us to figure that out.

宇宙正在膨胀，正是这种红转移让我们得以发现这一事实。

That's just what galaxy redshifts are telling us.

这就是星系红移告诉我们的。

Today you learned that distant galaxies show a redshift in their spectra, which means they're moving away from us.

今天你知道了遥远的星系在它们的光谱中显示出红移，这意味着它们正在远离我们。

Remember, redshift stretches the wavelength of light.

记住，红移延伸了光的波长。

Then those can be compared to the supernovae redshifts, which is a different way of getting their distance.

然后可以将之与超新星的红移相比较，这是一种不同的距离测量方法。

It was as if the predictions based on the redshifts were underestimating the distances to the exploding stars.

似乎基于红移的预测低估了到爆炸恒星的距离。

Out away from earth you drift, This is known from your redshift.

你远离地球漂流， 这是从你的红移中得知的。

When light loses energy its wavelength gets longer — that's what cosmological redshift is.

当光失去能量，它的波长会变长，这就是宇宙学的红移。

And this trend of distant galaxies moving away from us, and from one another, is called cosmological redshift.

这种遥远星系 远离我们、彼此远离的趋势被称为 宇宙学红移。

Using the idea of lookback time, they could predict how far away it would be from us, and therefore calculate its redshift.

利用回溯时间的概念，他们可以预测它离我们有多远，从而计算它的红移。

Thanks to the next-generation GPU architecture in M3 Max, you can model and iterate remarkably complex 3D content in Cinema 4D with Redshift.

得益于 M3 Max 的新一代 GPU 架构，你可在 Cinema 4D 中 用 Redshift 对极复杂的 3D 内容进行建模和迭代。

I wanted to explore the whole universe, not just whatever I can see, you know, before the redshift kicks in.

我想探索整个宇宙，而不仅仅是我能看到的一切， 你知道，在红移开始之前。

This is very similar to the Doppler redshift I've talked about in earlier episodes, and is called a gravitational redshift.

这和我之前讲过的多普勒红移非常相似，被称为引力红移。

We discussed redshift and used Hubble’s Law to calculate how much certain parts of the universe are expanding away from us.

我们讨论了红移并使用哈勃定律来计算宇宙的某些部分正在向远离我们的方向膨胀。

On their merry-go-round path, one undergoes a redshift as it moves away, and the other has a blue shift as it moves toward us.

在它们旋转的轨道上，一颗在远离地球时发生红移，另一颗在靠近地球时发生蓝移。

We discussed redshift and used Hubble's Law to calculate how much certain parts of the universe are expanding away from us.

我们讨论了红移，并使用哈勃 定律来计算 宇宙的某些部分正在远离我们膨胀的程度。

When you're right at the event horizon, just when an outside observer would see your clock stop, they'd also see the light coming from you infinitely redshift!

若你正好在事件视界之中，当外部观察者看到你的时钟停止时，他们也会看到来自你无限红移的光！

And if that wasn't strange enough, astronomers such as Edwin Hubble noted that the amount of redshift is proportional to the distance from Earth.

如果这还不够奇怪， 埃德温·哈勃等天文学家指出，红移量 与到地球的距离成正比。

The redshift of distant galaxies and the cosmic background are not the only confirmations we have that the Big Bang model is correct.

遥远星系的红移和宇宙背景并不是唯一能证明大爆炸模型是正确的。
