Hey there! Welcome to Life Noggin.
大家好！欢迎来到脑洞大开的生命奇想！
Have you ever wondered if it was possible to freeze a person right after they die and bring them back to life sometime in the future?
你有没有想过，如果人死后，马上冷冻起来，是否有可能在将来某个时候让他们复活？
Grab your winter coats, this could get a little chilly. No, no. That's actually a little chili. Animator, I was talking about the cold. Thank you.
穿上你的冬衣，这可能会有点冷。不,不。这是辣椒。动画师，我是说冷。谢谢！
The practice of preserving bodies in extremely cold temperatures with the hope of reviving them in the future is called cryonics.
在极冷的温度下保存尸体，以求在未来能够复活他们，这种做法被称为人体冷冻法。
This is not to be confused with cryogenics, which is basically just the study of things at very low temperatures and probably wouldn't make for that interesting of a video! But who knows.
这和低温学是不一样的，低温学基本上只是研究低温中的事物，很可能做不出有趣的视频！但谁知道呢。
The idea with cryonics is that it would keep a person in cryonic suspension until the science of the future brought a way to bring them back to life.
人体冷冻法认为，将人置于冷冻悬置中，直到未来的科学找到方法让他们复活。
Theoretically, if their cells were not irreparably damaged, then that person might be able to be resuscitated some time in the future.
从理论上讲，如果他们的细胞没有受到不可修复的损伤，那么这个人在未来的某个时候可能会被复活。
Or you can be like me and live forever on the internet! Boys, have I seen some stuff? So what's the process cryonicists follow to try to preserve a person?
或者你可以像我一样，永远生活在互联网上！孩子们，我看到什么东西了吗？那么，为了保存一个人，人体冷冻工作者要遵循什么程序呢？
Well, after a patient is pronounced legally dead, they stabilize the body and supply the brain with oxygen and blood.
在一个病人被宣布死亡后，他们要稳定身体，给大脑提供氧气和血液。
The body is then packed in ice and injected with an anticoagulant to help keep blood from clotting during the travel to the cryonics facility.
然后，身体被放入冰块中，并注射抗凝剂，以防止血液在运送到冷冻设备的过程中凝固。
They then try to replace some of the body's water with a cryoprotectant, which basically acts like human antifreeze.
然后，他们试图将人体内的一些水换成一种冷冻保护剂，这基本上和人类的防冻剂一个作用。
This helps to protect the organs and tissues from ice crystals after the body is put into a state of suspended animation due to a process called vitrification.
这有助于保护器官和组织，在身体由于玻璃化过程暂时失去活力后，避免结出冰晶。
Once the water is replaced, the body is further cooled and placed in a container in a large metal tank filled with liquid nitrogen around -196 degrees Celsius, completing the process.
一旦水被替换，身体就会被进一步冷却，并放入一个容器中，这个容器放在装满液态氮的大金属罐里，大约零下196摄氏度，整个过程就完成了。
Now, some scientists believe that this process isn't sufficient enough to actually put a body in cryonic suspension, but assuming a person is successfully preserved, does that mean scientists can bring them back to life?
现在，一些科学家认为这一过程还不足以使人体处于低温悬浮状态，但假设一个人被成功地保存下来，这是否意味着科学家可以让他们复活？
Well, in today's world, no. But is it possible in the future? Some scientists have their doubts, but others seem to think so based off of similar scientific studies.
在目前的情况下，不可以。但在未来有可能吗？一些科学家对此持怀疑态度，但其他人似乎认为可以，有些类似的科学研究可以提供依据。
One study showed that certain roundworms retained behaviors that they had learned before they were cryopreserved after they were vitrified and revived.
一项研究表明，某些蛔虫在被玻璃化和复活后，保留了它们冷冻之前学过的行为。
Another study showed that sheep ovaries could be cryopreserved, thawed, and then still work after being transplanted into a cute little ball of wool, even when analyzed 6 years after the procedure!
另一项研究表明，绵羊卵巢可以被冻存、解冻，然后在移植到羊的身体后仍能正常工作，甚至在手术后的6年后也是如此！
Now, both of these studies are obviously not the same as human cryonics, but they provide some hope into what is possible.
这两项研究显然都与人体冷冻法不同，但它们给了我们希望，可以期待可能出现的情况。
Not only that, but practically every type of cell has been successfully cryopreserved which is a small, but significant step to human cryonics.
不仅如此，几乎每一种类型的细胞都成功地进行了冷冻保存，这是人类冷冻技术的一个小而重要的步骤。
It doesn't seem to be scientifically sound to completely conclude one way or another if the cryonics of today combined with the science of the future will lead to bringing a person back to life.
今天的人体冷冻技术和未来的科学结合在一起，是否会使人复活，现在下结论，似乎并不是很科学。
It seems more science fiction than reality, but so did invisibility cloaks at one time, and we already showed we're on the path to making those possible! So what do you think?
比起现实，这似乎更像是科幻小说，但隐形斗篷也曾经是这样，而且我们已经证明了我们正在努力使这些成为可能！你是怎么想的呢？
Will the scientists of the future really be able to bring back people in cryonic suspension?
未来的科学家真的能让冷冻悬置中的人复活吗？
Do you think people should even freeze themselves? Let me know in the comment section below!
你认为人们应该冻结自己吗？请在评论区告诉我！
And if you are interested in the comment that I made on the invisibility cloaks then you should probably check out this video.
如果我对隐形衣的评论，你很感兴趣的话，你应该看看这个视频。
Believe it or not, scientists are getting kinda close to making these dreams come true.
信不信由你，科学家们正在接近这些梦想。
And you don't have to live in a major copyrighted movie franchise to experience it. The key is distorting the way light bounces off an object.
而且你不用去看受版权保护的大电影才能体验它。关键在于改变物体反射光线的方式。
As always, I'm Blocko and this has been Life Noggin. Don't forget to keep on thinking!
我是宝高，这里是脑洞大开的生命奇想。思考不要停！
