China's hidden wonder: The world's deepest & cleanest dark matter laboratory

中国隐藏的奇迹：世界上最深、最干净的暗物质实验室

in 2007 a Hydro power company based in Sichuan Province China set out on the most ambitious and challenging hydroelectric project in the world to become the largest underground power station they began Excavating massive tunnels under the ing mountain four large 16.7 kmet long tunnels carrying water East to 17.5 km from employee commuters and a water drainage tunnel

2007年，中国四川省的一家水电公司开始了世界上最雄心勃勃、最具挑战性的水电项目，建一个最大的地下电站。他们开始在锦屏山下挖掘大型隧道——四条16.7公里长的大型隧道，将水输送到东17.5公里的员工通勤区和一条排水隧道

today this is the basis of the world's deepest and largest underground Physics laboratory and also the world's largest and cleanest Dark Matter search facility

in the vast Universe visible matter varying in size from a grain of dust to a planet like Earth or a nebular these account for just 5% of the universe the remaining 95% consists of dark matter and dark energy

今天，这里是世界上最深、最大的地下物理实验室，也是世界上最大、最干净的暗物质搜索设施

在浩瀚的宇宙中可见物质大小不等，从一粒尘埃到像地球或星云这样的行星，这些物质只占宇宙的5%，其余95%由暗物质和暗能量组成

the probability of Dark Matter interacting with visible matter is so small that it's difficult to detect it directly while ubiquitous cosmic rays can also so greatly interfere with our efforts to detect Dark Matter therefore a laboratory that can Shield cosmic rays and provide an experiment environment with facilities with an extremely low radiation background becomes a prerequisite for Dark Matter detection underground Laboratories are typically used not because the dark matter is concentrated there but because their deep underground location provides a natural shielding against this interference

暗物质与可见物质相互作用的可能性很小，很难直接探测到它，而无处不在的宇宙射线也会极大地干扰我们探测暗物质的工作，因此，需要一个能够屏蔽宇宙射线并为实验环境提供具有极低辐射背景的实验室，不是因为暗物质集中在那里，而是因为它们位于地下深处，可以屏蔽干扰

以下是各国网友的评论：

What a fantastic facility! It’ll be interesting to see what they find in the next few years. It’s a pity that we don’t have anything similar

多棒的设施啊！看看他们在未来几年的发现会很有趣。很遗憾，我们没有类似的实验室。

Hats off to the Chinese physicists for taking advantage of the industrial dam project and setting all this up! A really informative video, Dr Maggie

向中国物理学家致敬，他们利用了工业大坝项目并建立了这一切

这真是信息量很大啊

Very interesting, I’ve never heard about this CJPL facility mentioned in other videos before. How are they planning to detect dark matter… xenon, geranium sensors?

非常有趣，我从来没有在其他地方听说过这个CJPL设施。他们打算怎么探测暗物质?

walter7837

We have deeper mines than that , but getting everything through the mineshaft(s) would be rather impractical if you want to set up a facility. And they have all the electricity they need right next door !

我们有比这更深的矿井，但如果你想建立一个设施，让所有的东西都通过审批是相当不切实际的，即使他们需要的电力就在隔壁

Very nice video. I love great engineering. If they have a chimney it will be a long drop for Santa.

我喜欢伟大的工程。如果有烟囱，圣诞老人要滑很久。

adalberteinstin5137

Very nice. So now there are more than two such detectors on earth, like nuclear reactors can be made.

很好，现在地球上有两个以上这样的探测设施了，就像核反应堆一样可以被造出来。

I just found your channel and I am intrigued. Though you are an Astrophysicist, I would like to ask if you could enlighten me, what comprises the ozone layer and what causes resistance to returning space craft? From what I understand the only gas in the ozone layer that has a solid particle is carbon, CO2 and yet all plant life on earth depends on it. So reducing carbon footprint is it wrong? As far as I know only CO2 gases with a solid atom is able to cause that much friction.

虽然您是一名天体物理学家，但我想问您是否可以告诉我，臭氧层是由什么组成的？是什么导致了太空飞船返航的阻力？

据我所知，臭氧层中唯一有固体颗粒的是碳，二氧化碳，而地球上所有的植物都依赖于它。那么减少碳足迹是错的吗？据我所知，只有含有固体原子的二氧化碳气体才会产生这么大的摩擦。

The astrophysicist I know calls dark matter an "observable effect for which a cause has not yet been discovered."

我认识的天体物理学家把暗物质称为一种“尚未发现其原因的可观测效应”。

great video, the science china is doing is hardly talked about in the US

很棒，中国所做的科学研究在美国很少被谈及

DavidBrant

Amazing facility in Sichuan. Makes me wonder why such facilities are built on the earth or underground when we can already send equipment into deep space and try to detect DM & study Neutrinos out there, or does the anechoic nature of water underground isolate better? Surely once we get science bases onto the moon it would be a more sterile environment?

这个位于四川的设施很神奇。我想知道，当我们已经可以将设备送入深空并尝试探测和研究那里的中微子时，为什么要在地球或地下建造这样的设施，或者地下水的消声性更好？一旦我们在月球上建立科学基地，月球肯定会变得更加贫瘠吧?

Amazing Chinese endevour! Hope we detect it soon!

中国的努力令人惊叹！希望我们能尽快发现暗物质

Very interesting, China leading the way in this field.

非常有趣，中国在这个领域处于领先地位。

One of the most interesting things to me is the recent information that black holes are emmitting non baryonic matter AKA dark matter. I theorize that black hole singularities rip apart string membranes and this is dark matter and because it's not made of strings we cannot observe it. This information is going to help bring rational Minds back to the Big Bang and help people realize AE past lightspeed is a illusion of blackholes (like the one at the center of our galaxy) emmitting non baryonic matter increasing its local density creating illusion of AE past lightspeed. The labs can have different uses... not a total waste of funding.

对我来说最有趣的一件事是最近的信息，黑洞正在发射非重子物质，也就是暗物质。我认为是黑洞奇点撕裂了弦膜，这就是暗物质，因为它不是由弦构成的，我们无法观察到它。这些信息将有助于理性思维回到大爆炸，并帮助人们认识到超过光速的声发射是黑洞的幻觉(就像我们银河系中心的黑洞)发射非重子物质，增加其局部密度，产生超过光速的声发射幻觉。实验室可以有不同的用途，并不完全是浪费资金。

vazap8662

Great video but I'm not sure I understand.. Isn't the nature of DM by definition unknown? Aren't we talking about neutrino detection here? Or is the consensus here that DM = neutrinos? I never heard that was anything else but hypothetical right?

很棒，但我不确定我是否理解了，暗物质的本质从定义上来说不是未知的吗?我们不是在讨论中微子探测吗？还是大家一致认为暗物质 =中微子？我从来没听说过，这是假设，对吧?

Dark matter detection?? Cool!

暗物质探测？太酷了!

jimcabezola3051

Good gosh! After all this effort, the folks at CJPL and DURF deserve every success and the best fruits of their labours! Let's get all this dark matter stuff settled, for starters!

天哪！经过所有这些努力，CJPL和DURF的工作人员理应获得成功和最好的成果！首先，让我们解决暗物质这个问题吧!

Super eye opening

Dark matter might not even exst. A number of world renown distinguished scientists doubt the exstence of dark matter, thus explaining why it is so difficult to observe or detect, i.e. it is not there. The alternative to dark matter theory is that the standard gravitational theory needs revision to explain the many anomalies that are observed in space that conflict with the standard gravitational theory. It is these anomalies that were tried to be explained by the invocation of dark matter. It is possible that a modification to the standard gravitational theory might be able to explain the observed anomalies without the need for an invisible and undetectable dark matter.

暗物质可能根本不存在。许多世界著名的杰出科学家怀疑暗物质的存在，从而解释了为什么它如此难以观察或探测，即它根本不存在。暗物质理论的替代方案是，标准引力理论需要修正，以解释在太空中观测到的许多与标准引力理论相冲突的异常现象。正是这些异常现象让我们试图用暗物质来解释。有可能，对标准引力理论的修正可能能够解释观测到的异常现象，而不需要不可见和不可探测的暗物质。

Salute to wise and smart Chinese Scientists making great use of deep underground to setting up the "Dark Matter" research lab which closely suitable for the 'Dark Matter" study

向聪明的中国科学家们致敬，他们充分利用地下深处建立了与暗物质研究密切相关的“暗物质”研究实验室。

copperhead2534

So, the Aetheric Field is now coined "Dark Matter", up from "Quantum Goo", It is non material in nature, good luck.

以太场现在被称为“暗物质”，它是非物质的。

I hope they do a better job there than they do manufacturing zippers that don't zip and ball point pens that don't write.

我希望他们在这方面做得更好，他们生产的拉链拉不上，圆珠笔写不了字。

TheMurrut

Hidden, and you'll never find it, just like dark matter, because neither exsts.

隐藏的，你永远找不到它，就像暗物质一样，因为两者都不存在。

What happens when the upstream dam fails and floods the whole thing??? Tofu-Dreg physics laboratory!

如果上游大坝坍塌，整个地区被洪水淹没，会发生什么？豆腐渣物理实验室

is it possible to measure dark matter? i always thought that it wasnt..

有可能探测到暗物质吗？我一直认为不能……

Richardz

It is advisable to approach news from China with a degree of skepticism, as there are instances where the information may be only partially true or outright false. Claims of progress are sometimes exaggerated, and instances of plagiarism are not uncommon.

明智的做法是对来自中国的新闻持一定的怀疑态度，有些情况下，这些信息可能只有部分是真实的，也可能是完全假的。

取得进步的说法有时被夸大了，抄袭的例子也并不少见。

robertgardner8661

Who gets the nobel prize if they detect it? Like who among the many people involved in the project.

如果他们发现了暗物质，谁会得到诺贝尔奖？参与这个项目的人这么多。

Everything seems to happen n Sichuan.

一切似乎都发生在四川。

I just hope they don't make contact with the Trisolarans.

我只希望他们不要和三体人接触。
