创造一个新行星

Hey there! Welcome to Life Noggin.

大家好!欢迎来到脑洞大开的生命奇想。
These days it seems like everyone wants to go into space and colonize new planets.
如今,似乎每个人都想进入太空,开拓新的星球。
With global threats such as climate change and other factors like a growing world population and Triangle Bob's never-ending appetite, it's probably a good idea to expand humanity's foothold throughout the galaxies, but it had me wondering.
当前气候变化威胁全球,世界人口不断增长,鲍勃的胃口永无止境,种种情况不断出现,因此在整个星系中扩展人类的立足点或许是个好主意,但这令我很疑惑。
行星

Rather than rely on another pre-existing planet, could we make a new, habitable planet ourselves?

与其移民到另一颗已经存在的行星,我们能不能自己创造一个新的、适合居住的行星呢?
Now before we begin, it's best to know that we are going to be making a lot of assumptions here and there will be a world of other factors to consider than we bring up in this video.
首先,要知道我们在这里会做很多假设。实际操作中会有很多其他的因素要考虑,我们在这个视频中提到的只是一小部分。
And even if it is possible, it likely won't happen for a very long time.
即使这有可能实现,也要等很长时间之后了。
But for curiosity's sake, let's go exploring! I just hope we end up like the rover and not the cat.
但是为了满足我们的好奇心,我们去探索一下吧!我只希望我们最后能像漫游者而不是猫一样。
To start off, if we'd want to be living on it, we should to find a good spot in space to put the new planet.
首先,如果我们想住在上面,我们应该在太空中找个好地方来安置这颗新行星。
We'd want it to be in a habitable zone, meaning the planet should have an orbit the right distane from its star to ensure optimal temperatures and most importantly, liquid water.
我们希望它处于一个适宜居住的区域,这意味着这颗行星的轨道应该与它的恒星保持适当的距离,以确保能有最佳的温度和最重要的液态水。
Too close of an orbit to its star and the planet would be a good home for a Human Torch.
如果轨道离它的恒星太近,这颗行星将成为霹雳火的好归宿。
Too far away and the planet would most likely be in a deep freeze.
如果距离太远,这颗行星极有可能处于深度冰冻之中。
We'd also need the right materials to make the planet.
我们还需要合适的材料来制造这个星球。
Our Earth has a core made of mostly iron and nickel, then its mantle, which is comprised of mainly silicate rock with elements like magnesium, aluminium, oxygen and more.
地球的核主要由铁和镍构成,然后是地幔,主要由硅酸盐岩石构成,其中含有镁、铝、氧等元素。
On top is the crust, which has some similar materials, but throws in more things like calcium, sodium, and potassium.
最上面是地壳,有些物质是相似的,但多了很多东西,如钙,钠,和钾。
If we made our own new planet, we'd probably want it to have similar elements and a similar structure.
如果我们创造了自己的新行星,我们可能希望它有相似的元素和类似的结构。
We'd also want a bunch of water to form some oceans, as most of the Earth's surface is covered in it.
我们还想要很多水形成海洋,因为地球的大部分表面都被水覆盖。
Someone should probably start running the faucet now.
现在应该有人拧开水龙头了。
But even if we get all of the materials, actually creating a new planet like Earth could prove troublesome.
但是即使我们凑齐了所有的材料,实际上创造一个像地球一样的新行星可能会很麻烦。
It might be a better route to make something more like a giant space station.
把它做成一个巨大的空间站可能会更好。
We've already made the International Space Station and plenty of space vessels, so this could be more in our wheelhouse.
我们已经建造了国际空间站和许多太空飞船,所以这对我们来说应该不算难事。
It would still require a lot of material and be pretty expensive if we wanted it to be super big, say the size of our moon or a small planet.
如果我们想把它做得超级大,比如像我们的月亮或小行星那么大,就需要大量的材料,那么价格就会非常昂贵。
By comparison, it's been estimated that it would take around 850 quadrillion dollars to build a real-life Death Star.
相比之下,估计建造一个真正的死亡之星需要大约850万亿美元。
Either route we go, we'd probably also need a lot of food, since there's going to be a bunch of scientists and astronauts out in space working on this project!
不管我们走哪条路,我们可能还需要很多食物,因为将会有一群科学家和宇航员在太空中完成这个项目!
According to NASA, their average astronaut uses about 0.83 kilograms of food per meal, with 0.12 kilograms of that being packaging material.
根据美国国家航空和宇宙航行局(NASA)的数据,他们的宇航员平均每餐要消耗0.83公斤的食物,其中0.12公斤是包装材料。
Excluding the weight of the packaging material, this would mean we'd need roughly 780 kilograms of food just to feed one astronaut out in space for a year on a 3-meal-a-day diet.
除去包装材料的重量,这就意味着,一名宇航员每天3餐的话,一年需要大约780公斤的食物。
One thing that can prove useful for any type of space colonization is having the ability to have a giant magnetic shield to protect our new homes.
有一件事对任何类型的太空殖民都是有用的,那就是能有一个巨大的磁盾,来保护我们的新家。
NASA recently announced that they want to try and deploy a magnetic shield around Mars to make the atmosphere more livable through things like protection from solar winds and radiation.
美国宇航局最近宣布,他们想尝试在火星周围部署一个磁屏蔽装置,通过诸如屏蔽太阳风和辐射之类的措施,使大气层更适于居住。
Having something like that at our disposal could help us with a variety of space missions, including terraforming, which we did a video on.
有了这样的东西,我们可以完成各种太空任务,包括地球化改造,我们做过一个相关视频。
Putting all this together could be the start of making our own planet one day!
有了这一切,我们才可以开始自己的星球!
In reality, creating a new planet would probably require extremely advanced technology and there would be tons of other things to consider.
事实上,创造一个新的星球可能需要非常先进的技术,而且还需要考虑很多其他的东西。
But if we could one day do it, what would our new planet be called?
但如果有一天我们能做到这一点,我们的新地球要取什么名字?
Let me know in the comments section below! Have you ever wondered how much space is worth? If so you should definitely check out this video.
请在下面的评论区告诉我!你有没有想过太空值多少钱?如果想过的话,你一定要看看这个视频。
One asteroid that passed us in 2015 likely contained 90 million metric tons of these metals... worth up to 5 trillion dollars.
一颗2015年从我们身边经过的小行星可能含有9000万公吨的这种金属……价值高达5万亿美元。
