为什么我们不能穿墙而过?

How Could You Walk Through Walls?

嘿 看这里!
Hey,there!
欢迎收看品生活
Welcome To Life Noggin!
宇宙中的一切都是由原子构成的
Everything in the universe is made up of atoms.
原子的99.9999999%是空的
Atoms are 99.9999999%
这意味着我们人类
empty space.So that means you humans,
想穿过的墙和周遭的一切
the walls you want to walk through, and everything around you
几乎都是空心的 这实在令人震惊
is mostly empty space. It ’ s mind boggling,
但是如果那是真的
but if that’s true,
为什么我们不能从空隙中穿过呢
why can’t we past through the empty space
原子是由电子以及由质子和中子构成的原子核组成
Atoms are made of electrons and nucleus containing protons and neutrons.
我们通常看到的原子是这样的
We usually see atoms drawn like this,
但是这些示意图和实际比例不符
but these sketches are nowhere near to scale.
我们把原子的大小比喻成西瓜
Let’s say an atom is the size of a melon.
如果真那样 电子和原子核就会很小
If that’s the case,that nuclears andelectrons
根本看不见
would be too small to even see!
所以确实 有很多空出的地方
So yeah, there’s a lot of empty space.
但不完全是空的
But it’s not entirely empty.
在那些原子的草图中
In those basic sketches of atoms,
通常显示电子轨道绕着原子核运动
it’s usually illustrated that electrons orbit around the
就像行星绕着太阳那样 但是事实上
nucleus just like our planet orbits the sun.But in actuality,
电子以云的形态在那些空出的地方聚集
electrons swarm around that empty space in cloud formations.
把它想象成风扇 看起来有很多
Think about it like a fan. It may seem like there’s
空余空间 但是开关打开
lots of empty space, but when it’s turned on,
你可以马上看到扇叶几乎无处不在
you can see that the blades are basically everywhere all at once.
理论上 如果你现在试着把你的手
Now,theoretically, if you tried to stick your hand
伸进那个风扇 你会看到你的
into that fan,you’d see that your hand and the fan
手和扇叶不可以同时在同一个地方
blades can’t exist in the same place at once… No,
一根筋的Bob 我是说理论上
Triangle Bob, I said said theoretically!
任何两样东西都不可能同时在同一个位置
Anyway two things can not exist in the same place
电子也是如此
at once and the same goes for electrons.
这个就是泡利不相容原理
This theory is called the Pauli ExclusionPrinciple.
没有两个电子可以处在同样的位置或者结构中
No two electrons can be in the same stateor configuration.
基本上
On a basic level,
这就是你为什么不能穿过墙的原因
this is why you can’t walk through walls. So,
同样 你也就不能穿过一个物体
you can’t pass through an object,
但是你知道你甚至也不能触摸到
but did you know you actually can’t even touch
它们吗?
them either?
如果你真的把手伸进风扇
If you did stick your hand in that fan,
你可能会感受到扇叶在击打你的手
you probably feel the blades hitting your hand, but you
但是实际上你感受不到那些扇叶
wouldn’t actually be feeling the blades.
你从来没有真正感受过一个物体 是的
You’ve never truly felt an object ever! Yes,
我知道这听起来很奇怪 但是淡定
i know this sounds pretty wacky, but bear with us.
你知道磁铁同极互斥吗?
You know how the negative end of a magnet repels other negative magnets?
这就是你试图触摸时发生的事情
That’s what’s happening when you try to touch anything.
就好像你和你所触摸的一切
It’s like there’s a little invisible force field
之间有一个无形的力场
between you and everything you touch.
即使遭受外力也从来不会被破坏
It’s poked and prodded, but never broken.
宇宙中的一切也是这样的
It’s the same with everything else in theuniverse too. Now,
现在你明显不能
you obviously can’t,
但是如果你真的穿过了一面墙
but if you were to actually walk through a wall, it would
这真的打破了科学
basically break science.
电子是费密子 而且必须遵守泡利不相容原理
Electrons are fermions and have to obey thePauli Exclusion Principle.
但是另一种亚原子颗粒玻色子不遵守
But bosons, another type of subatomic particle,don’t.
如果费密子开始像玻色子一样运动
And if fermions started acting like bosons,
整个宇宙会变得非常奇怪
the Universe would be a very weird place.
想想就头痛
My head hurts just thinking about it.
但是我们不是完全没有希望
But we aren’t completely hopeless!
还有量子隧道
There’s still quantum tunneling,
在隧道里一个细小的微粒
which is where a very tiny particle can make its way
可以穿过屏障 但是根据经典力学
across a barrier even though, according to classical mechanics,
它还没有力量做到
it doesn’t have the energy
这不是什么古怪的主意
to do so. And this isn’t just some wacky idea —
隧道效应被应用于扫描隧道显微镜
tunneling is used in scanning tunneling microscopes. Basically,
电子在土壤表面和
electrons have a small probability
显微镜尖端有一个
of tunneling between the surface of the solid
小隧道
and a tiny tip on the microscope.
如果你想用这一现象穿墙
If you wanted to use phenomenon to walk through walls,
你需要保证体内的
you’d need every single particle
每个微粒都穿过障碍物
in your body to tunnel through the barrier.
可惜的是那个事件发生的可能性微乎其微
And sadly, the probability of that happening is very, very small.
还是感谢我的制作者 让我可以穿过任何我想穿过的事物 看见没
Thanks to my animator though, I can pass through whatever I like. See?
虽然这让我感到有点滑稽
Although it does kinda make me feel funny right after.
如果让你选一种超能力 你会选什么?
If you could choose one super power, what would it be?
