So you want to visit a black hole. You’ve packed your bags, 听说你打算去黑洞。你已经打包好了行李，
you've updated your passport, and you’re basically ready to jump on a spaceship and blast off. 更新了护照，就等着跳上飞船，点火起飞。
However, before you do that, I have just one piece of advice: 但是，在出发前，且听我一点小提示：
Don’t. 别去.
Ok…if you really MUST go, 额...如果你坚持要去的话，
I suppose you should at least know a few things about black holes before you leave. 我想，至少在走之前， 你需要了解一点关于黑洞的东西
First, you should know exactly what a black hole IS. 第一，你必须需要 知道的：黑洞究竟是个啥？
A black hole is a physical object in space, just like everything else. It’s made up of a tiny but massive 黑洞是太空中的一种物体， 就像其他东西一样。它是一个极小的，
point where gravity and density are infinite, a line beyond which everything, 但质量极大的'点'。 在那里,引力和密度是无限大的.
Including light, can only fall INTO that tiny point, and sometimes some glowing stuff orbiting around it 在那里，有一条线：所有一切，包括光，都最终落入那个小点。 偶尔，有些发光的东西，会环绕着它转圈圈.
and maybe some radiation. So basically, here 也许还有些辐射。所以，基本来说，
Is kinda bad, here is really bad, and here is safe. 这里：有点糟，这里：非常糟，这里：安全。
Also, black holes mostly come in two sizes. Don’t ask me why—we still aren’t sure. 还有，黑洞大致上分为两种尺寸。 别问我为什么，我们也不知道。
However, a black hole is also NOT a lot of things. 不仅如此，黑洞绝对不是以下：
It is not a hole, a cosmic vacuum cleaner, a portal to another 它不是一个洞；不是宇宙吸尘器；
dimension populated by unicorns and space potatoes, and absolutely NOT 不是通向另一个充满独角兽和太空土豆的维度的大门 而且，绝对不是
a good place to vacation. 适合度假的地方
Ok, fine. I guess next you’ll need to know how to FIND a black hole. 好叭，我猜，你接下去想知道的， 就是如何找到一个黑洞。
Though technically black holes could just sneak up behind you, they likely won’t. The nearest 尽管，操作上来说，黑洞可能会 偷偷的躲在你背后冒出来，但实际上大多时候，它不会。
known one is 3,000 light-years away anyway. However, if you WERE to go looking for one, 人类最近距离已知的一颗，也在3000光年以外。 但是，假如你一直在寻找一颗黑洞.
there are a couple of good ways to find them. First, black holes 有一些不错的搜寻方法。首先，
tend to mess with their environments, so you can sometimes use interesting clues, such as 黑洞通常都会跟周围环境混在一起，所以， 有时候你需要利用一些有意思的线索，比如
A bunch of stuff orbiting what appears to be…nothing. 有一大堆物体环绕着似乎...啥都没有在运转
And second, as we mentioned before, there’s often glowing stuff orbiting around them, caused by, well, 其次，如前所述，总有些 闪闪发光的东西环绕着它们
when things get too close. So now that you’ve FOUND a black hole 当距离足够近时，你就会发现一颗黑洞
and CLEARLY aren’t listening to me saying not to go, it’s time for a few important 鉴于你完全无视我不要去的建议 是时候给你一些
safety considerations. First of all, the GOOD news is that 重要的安全提示了。首先，好消息是，
as long as you stay far away, black holes aren’t all that bad. 只要你离黑洞够远，黑洞也并不完全那么糟
However, as you get close, you need to keep a few things in mind. The radiation near the black hole 但是，随着逐渐接近，你需要把这些事情牢记在心。 黑洞附近的辐射
can be extremely deadly,the chances of escape get slimmer the closer you get, 是极度致命的，你越接近黑洞，逃走的机会就越低
and, if you get close enough, you now have to worry about being stretched into a giant noodle 并且，假如离的足够近，你就该开始担心 下自己会被拉长成一根巨大的面条了
and time getting really weird. So, unless you have great radiation shields, 时间也会变得十分古怪。所以， 除非你拥有一个非常厉害的辐射防护盾，
a faster-than-light spaceship, or you’re completely indestructible, you should probably ，一艘跑的比光速还快的宇宙飞船， 又或者你本人是无敌不死之身，
just stay away. Well, that pretty much sums up black holes 你就真的该离黑洞远一点。 好啦，关于它
at least, before things start getting really complicated. But, before you go for real, 在事情变得非常棘手之前，我大致要说的就这些。
please refer to the handy brochure in your spacesuit pocket, since there’s quite a bit to remember.
Now then, remember your tickets, enjoy your trip, and please…
…be careful.
