A beast in particular it tears everything to its step
并把星球吞并，就像吃开胃小菜
it devours and it like appetizer in a cocktail.
它是宇宙中最怪异，最具破坏性的现象之一
He is one of the strangest phenomena and destructive in the Universe.
它是宇宙中最怪异，最具破坏性的现象之一
黑洞
A black hole.
我认为黑洞
I believe that a black hole is
是宇宙中力量最强大的地方
the place more violent than any another one in our Universe.
就像走到了世界尽头
It is like passing the limit and not to be able to return.
无回头之路
我觉得，是种致命的吸引
It is fatal attraction, I suppose.
宇宙中的黑洞处
A black hole is a region of space where
地心引力非常大
the gravitational attraction
she is so immense that nothing it can escape of her.
什么的逃不掉，就连光也逃不掉
Not even the light.
天体，物理，运动三项全能的
The astrophysics and triathlete Feryal Ozel
费约.奥济尔
尝试去解决
it is trying to unravel the mysteries
黑洞引力周围的谜团
that they surround to this elusiva cosmic force.
黑洞里
In a black hole
引力太强大
the gravity is so strong that no other force
没有其他力能竞争得过它
任何物质都缩解为单个点
it can compete with her so everything colapsa in a single point.
奥济尔说
Ozel says
只要靠近黑洞，无论什么都西
that any thing that is with a black hole
都会成为潮汐般引力的牺牲品
she will be victim of its implacable one gravity force.
想象一下，你在游泳池里游泳
It imagines that you are swimming in a swimming pool.
没有水流
And there is no current.
你可以随意向哪个方向游
You can go in any direction that you want.
现在，假设你不在游泳池里游泳
Now it imagines that they remove to you from that swimming pool and you are in a river.
而是在河里游泳
想象一下，河中水流非常强
A current imagines that he is so strong
你只能朝一个方向运动
that the unique direction in which you could go would be with the current.
那就是水流方向
太空中黑洞附近地方，就类似于这条奔流的河
The space around a hole black acts like that wild river.
你摆脱不了这股强大的拖力
You could never fight against that enormous drag that you feel.
当一个物体接近黑洞边缘时
When an object approaches on the brink of madness a black hole
黑洞边缘叫做“视界”
call horizon of events, the point without return arrives.
这是不归路的临界点
随你离“视界”越来越近
To acercarte to this horizon of events
你就越靠近
you would already be approaching extremely fast
太空这种极快的运动
movement of the space underneath you.
接下来你唯一的移♥动♥方向就是进入黑洞
And you unique future direction are towards the black hole.
对于黑洞本身
The idea of a black hole, as a hole
作为一个洞，有时令人有点费解
sometimes it can to be a little confused.
它究竟是什么
What in fact it is, in some sense
某种意义上说
它是一个你永远也回不来的地方
it is, a place of which no you can return
至少不是以你进入的方式回来
at least not in the form that you entered.
黑洞难以发现
The black holes are difficult of to detect
因为就像这名字暗示的一样
because as it suggests its name
你看不见它，它是是黑暗的
you cannot see them by himself same, because they are black.
但科学家们
But the scientists have shortage a black hole
已发现一个黑洞
就在它侵蚀太空中其它物质的时候
when its gravity affects to another thing in the space
如侵吞一颗路过的行星
as a star that happens.
一个完全隔绝的黑洞是无法看见的
A black hole totally isolated he would not be visible.
从黑洞那，我们真正看到的
What we really see of a black hole
实际是黑洞周围盘旋的强放射性物质
it is the hot material that turns to his around that is being sucked.
正被吸入其中
所以，这些强力的黑洞附近
So in the proximity of these poderos black holes
你会发现许多辐射
you would have much radiation result of the black hole
辐射的产生由于黑洞
吸入物质，拉伸它，绞曲它
attracting material
stretching it and twisting it while it falls.
辐射就发生在，物质坠入黑洞过程中
黑洞侵食着近距离的所有物质
The black holes consume any thing to its reach.
并且有上百万亿的黑洞，潜伏于宇宙中
And there are thousands of million of them roaming in the Universe.
天体物理学家安德里亚.盖兹
The astrophysics Andrea Ghez
是世界主要黑洞猎手之一
she is one of the main hunting of black holes of the world.
黑洞并不挑食
The black holes are not at the table demanding
见一个吃一个
they will have dinner any near thing, so
它们很乐意吞气体
calmly they eat gas, a star or a planet.
它们也很乐意吞并一颗恒星或行星
当它吸食一个行星时
When a black hole dinner a star tears first it
它不会先把它撕碎
你可以想象成，软软的油灰被拉伸
you can think about putty being stretched
然后流动在水似的物体上
and soon only it falls in him, as water by the water-drainage.
接着被慢慢卷入
完全就像磨面粉
Totally it is pulverized.
我们认为，黑洞的产生
The black holes take place by the collapse of a massive star
是由于超大行星的瓦解
那种比太阳质量大25~30倍的行星
of 25 or 30 times the mass of the Sun or more.
当行星的生命快结束时
When the end arrives from its time of life
超大行星的地心开始燃烧
the massive star burning fire its nucleus completely
一直烧掉氦, 碳, 氮, 氧
creating helium, carbon, nitrogen and oxygen until arriving at the iron
烧到最后，只剩没有核能的铁
that no longer it owns nuclear fuel, and when the iron nucleus
当铁心重建出一块物质时
it reaches certain mass, arrives at a point where
会出现它自身无法再支撑的一点
no longer it can be stable
这时，铁心崩溃
and the nucleus colapsa even to form a black hole
直到形成黑洞
同时形成一颗超新星
producing to the same time one supernovates.
超新星传送出，超大能量的爆♥炸♥
The superNova radiates amounts enormous of energy
所以，超新星附近的物质将成灰烬
so, any thing in its proximity will be destroyed.
然后，爆♥炸♥后的残迹
Soon the rest of the explosion fall in just formed black hole.
坠入新形成的黑洞
似乎
黑洞吸引的关键在于向心引力
And it seems that the key of the attractiveness of the black hole it is the gravity.
向心引力把物质拉聚在一起
The gravity attracts the things
就像太阳把各大行星拉聚在一起一样
just as the gravity of Sun attracts planets.
实际上
行星的大部分时光，都是绕黑洞轨道，和睦地飞行
In fact, the stars will orbit calmly the black hole
most of its lives without being sucked
而不会被吸入其中
这些行星实际很安全
these stars are safe from the fatal attraction of the black hole.
不会被黑洞吸引而脱离轨道
但如果你要，大胆靠近的话
But if you venture to you closely together, extremely near the edge
非常接近黑洞边缘
你就会被吸入其中
then it will suck to you.
科学家认为
The scientists think that there are million of descarriados black holes
我们银河系中，存在难捉摸的黑洞
in our galaxy, the Milky Way.
因为我们不能够看见它们
And since we cannot see them easily
可能附近就有一个
some could be just to our side.
那么到底离黑洞多近
What so close must be something stops to be sucked by a black hole?
我们就会被吸入其中呢？
离黑洞，约地球到太阳间距离这么远
Too much near a black hole, it is more or less the distance enters
就算很近了
of the Earth to the Sun.
但那确实太近了
But that is certainly too much close.
对未来太空旅行者，死于黑洞
For the space travelling futures, the death by a black hole
会是种壮烈的死法
it would be a violent form to die.
黑洞杀死你的方法
The method by which a black hole matarte could
取决于黑洞有多大
it depends how on great is.
黑洞分两类
They come in two categories.
它们大部分是呈星状的黑洞
The majority is holes black of stellar mass
质量是太阳的5~30倍
that they have of 5 to 30 times the mass of our Sun.
如果是星状的黑洞
If the black hole is of stellar size
黑洞周围，潮汐般的力量大得足以
then the tide forces surround of the black hole
把你整齐地撕裂
they are sufficiently high they could desgarrarte
甚至在视界以外
even very far of the horizon of events.
就算你想坠入黑洞
If you wanted to fall in a black hole
你一定不会想，坠入这一种黑洞
certainly you would not want to do it in one of those.
它将把你撕成面条
It would turn you into espagueti.
但除了星状黑洞
But besides the stellar holes black, there are others are gigantic.
还有一种庞大黑洞
是太阳质量的百万至十亿倍
Of million to thousands of million of times the mass of our Sun.
现在，科学家们相信
And now the scientists create that these monsters
这种庞然大物占据着每个星系的中♥央♥位置，银河系也是
they have a central paper in each galaxy, including ours.
黑洞
Black holes
它们是
太空中最神秘、最具潜在危险的奇物之一
they are of but the mysterious ones and in power dangerous peculiarities of the space.
一个黑洞胃口非常大
A black hole has an appetite voracious, it sucks everything to its step
吞食途经的任何物质
吐出残渣
and escupe what it does not devour.
现在，科学家们发现
And now the scientists are shortage that there are massive super black holes
存在超大质量黑洞
比它同族的星状黑洞要大百万倍
that they are million greater times that its cousins of stellar masses.
证据显示
And the evidence suggests them holes massive super black
