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。

We know that the horizon should line up, so we read it as a level.

我们知道视界应该对齐，所以我们把它看成一个水准线。

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

，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.

Lu, Krichbaum, and Akiyama are members of the Event Horizon Telescope (EHT) project.

路如森、托马斯·克里希鲍姆、秋山一本都是事件视界望远镜项目的成员。

Anything inside the particle horizon is referred to as the known universe.

子视界内的任何东西都被称为已知宇宙。

We call this the particle horizon of the universe.

我们称之为宇宙的子视界。

So if it's true, what happens if you cross the particle horizon?

那么，如果这是真的，穿过子视界会发生什么？

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。

Beyond this horizon we don't know where we are coming from.

超出了这个视界范围， 我们看不到我们的起源。

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

没错，在黑洞视界边缘，虚子不断产生。

Your mind just slows down, and you see a tremendous expanse in the moment.

你的心灵逐渐平静下来，你的视界会极大地延伸。

Hi. You must be the guys from EzraVision.

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！

Now, as spin increases, r-isco decreases.

随着自旋增大，ISCO的半径会减小高达6倍，直到跟事件视界相等。

To travel to the particle horizon, we need to move through expanding space.

要前往子视界，我们需要穿越膨胀的空间。

" 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子。”

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

然而，洞没有像黑洞那样的视界，一个我们令无法返回的陷阱。
