人类挖穿地球计划：如果一直往下挖会挖到什么

你有没有想过，如果你一直往下挖，能否挖穿地球直接去地球另一面的国家？

Have you ever thought about whether you could dig straight through the Earth to reach a country on the other side?

人类目前挖到哪了？

实际上，人类目前挖的最深的洞是俄罗斯的科拉超深钻孔，深度可达12km, 但没钻透地壳。

如果说地球是个苹果的话，这相当于连苹果皮都没穿透。

That depth is the equivalent of not getting all the way through the skin of an apple.

一个有趣的事实是，地核有2900千米‌深，但太空只在100千米以外。

挖更深的话，会发现什么？

你会看到至少20亿年前的化石和微生物。

你会看到那段古老时期时地球的样貌和它的演化。

你会看到生命起源是什么样、气候是如何变迁的。

你会进入到一个前人从未发现过的原始世界。

You would see what the origin of life was like and how the climate changed.

You would enter a primordial world that has never been discovered before.

怎样才能挖更深？

深海海底是离地球内部最近的地方。比起陆地，从海底钻到地幔所需的距离更短。

因此，深海钻探船也是人类目前往地球内部挺进的最高效的途径。

Therefore, deep-ocean drilling ships are the most efficient means for humans to penetrate the Earth’s interior.

目前世界上最深的海洞是一艘日本钻探船钻的，在海平面以下8千米处，但也没钻透地壳。

So far, the deepest sea hole in the world was drilled by a Japanese drilling ship, reaching 8 kilometers below sea level, but it still did not penetrate the Earth's crust.

而两个月前，美国的大洋钻探船也正式退役。

在本月前，世界上只有两个国家有大洋钻探船。

人类钻透地壳的梦想要落空了吗？

Is the dream of humans penetrating the Earth's crust doomed?

“梦想号”有望实现人类梦想

11月17日，由中国自主设计建造的首艘大洋钻探船“梦想”号正式入列。

On Nov 17, China's first domestically built deep-ocean drilling vessel, named Mengxiang, meaning "dream" in English, was commissioned in Guangzhou, Guangdong province.

该船最大钻深可达11000米，有望打穿地壳，进入地幔，探寻地球最远古的奥秘。

The ship is able to drill as far as 11,000 meters beneath the sea. This offers the potential to penetrate the Earth’s crust, reach the mantle, and explore the most ancient mysteries of the planet.

这船不仅钻得最深，功能也最强大。

新鲜出炉的岩心在船上就能开始研究，该船建有九大功能实验室，满足海洋领域全学科研究需求，如微生物、地球物理等领域。
