The event horizon of a black hole had never been imaged.

黑洞也未曾被拍摄到。

Right. Near the event horizon, virtual particles are being created.

没错，在黑洞视界边缘，虚粒子不断产生。

In the end, you'd just freeze, never crossing the event horizon.

最终，你只会觉得身体僵硬，再也穿不过视界了。

You're just going to drift right through that event horizon.

只是刚好穿过那个事件地平线。

And if I may, that dark region is the signature of the event horizon.

如果可以的话，那黑暗的区域就是事件视界的标志。

Second, it should not contain any event horizons, which would block two-way travel.

其次，虫洞不能有任何的事件视界，这会阻挡我们双向通行的东西。

And another, where it crosses the boundary and plunges into the event horizon.

另一个场景是宇航员越过边界，坠入事件视界（时空曲隔界线，黑洞周围）。

" Hawking said that pairs of particles should be created at the event horizon."

“霍金说，视界可以产生成对的粒子。”

I mean, you wouldn't even notice falling into that event horizon if you were there.

如果你在那里，你甚至不会注意到掉进了那个视界。

The boundary where the pit begins is known as the black hole's event horizon.

这个大黑坑的边界被称为黑洞的视界。

In fact, black holes warp space-time so much that, at the event horizon, time essentially stops!

事实上，黑洞扭曲了时空，以至于在视界处，时间基本上停止了！

However, a person observing you outside of the event horizon would see a very different picture.

但是，一个在视界之外观察你的人将会看到一张迥然不同的图像。

If you looked at a black hole, what you'd really be seeing is the event horizon.

如果你观察一个黑洞，你真正看到的是视界线内部。

Just outside the black hole's event horizon, things can still get out.

就在黑洞的视界之外，物体仍然是可以出去的。

Anything that crosses the event horizon needs to be travelling faster than the speed of light to escape.

任何物质想要逃脱视界线内部，需要超过光速。

The last light you emit trickling up and out, away from the event horizon.

最后从你身上反射出去的光缓缓的从事界中溢出。

The question was, is there a cultural horizon, or event horizon, at which point knowledge drops to zero?

“问题是，是否存在一种文化视野或事件视野，会出现知识降为零的情况？”

At the event horizon, time comes to a standstill, while space, on the other hand, moves forward.

在视界，时间停止了，但在另一方面，空间仍在向前移动。

However, the wormhole has no event horizon like a black hole, a trap from which we can't return.

然而，虫洞没有像黑洞那样的视界，一个我们令无法返回的陷阱。

Black holes got their name because light can't escape them, beyond a certain radius, called the event horizon.

黑洞得名的原因是光无法逃脱一个特定的界面——视界。
