It's thought that a lot of Jupiter is made up of this metallic hydrogen.

人们认为木星分是由种金组成。

But if you somehow made it around a third of the way down, where the pressure is more than 100 gigapascals, you'd find metallic hydrogen, which continues all the way to the core.

但是如果用某种方式将压强降低至其三分之一，也就是100兆帕以上，你就会发现金，是一直存在于地核中物质。

Under millions of times the pressure of Earth's surface, at 10,000 degrees Celsius, hydrogen changes state into something called metallic hydrogen.

在相当于地球表面数百万倍气压、约 1 万摄氏度环境下，会转变成一种被称为“金”状态。

Metallic hydrogen is highly reflective, so if you tried using lights to see down there, it would be impossible, and it's as dense as a rock.

金具有高反射性，因此尝试用光看看下面，是不可能，并且它像石头一样稠密。

Like Jupiter, it probably has a rocky core several times the mass of Earth, surrounded by layers of ice and weird, metallic hydrogen.

就像木星，土星可能有一个比地球质量几倍岩石内核，被冰层和奇特金所包围。

This liquid metallic hydrogen makes up the majority of the planet's interior.

种液态金构成了木星内分。

Jupiter is still warm from its formation, and has an interior that's mostly metallic hydrogen, and it may not even have a core.

木星在形成时仍然是温暖，它内主要是金性，并且可能甚至可能没有内核。

At a depth of 40,234 kilometers or 25,000 miles, it will compress so strongly that it will become harder and denser than rock, turning into so-called metallic hydrogen.

在 40,234 公里（2万5千英里）深度，它会受到强烈压缩，变得比岩石更硬，密度更，变成所谓金。

So as you travel deeper, the buoyancy force from the metallic hydrogen counteracts gravity's downward pull.

所以当你下降得更深，来自金浮力，抵消掉向下重力。

Hydrogen molecules are forced so close together that their electrons break loose, forming an unusual substance called metallic hydrogen.

分子被紧紧地压在一起，从而使电子挣脱形成一种叫做金特殊物质。

The biggest change that takes place here is that metallic hydrogen now has the ability to conduct electricity.

发生最变化是，金现在具备了导电能力。

And into that liquid metal we inject a high temperature plasma of hydrogen.

我们向液态金中注入高温等离子体。

Metallic hydrogen will begin to form, and you'll be surrounded by it.

金将开始形成， 你将被它包围。

In a paper published last week in the journal Science, two researchers from Harvard University announced that they’ve done what physicists have been trying to do for 80 years: they’ve created solid metallic hydrogen.

在上周发表于《科学》杂志一篇论文中，两位来自哈佛学研究人员宣布， 他们完成了物理学家80年来一直试图做到事情：他们制造出了固态金。

And if we could figure out how to make this stuff, it would be incredibly useful: It’s thought that metallic hydrogen would be a superconductor at room temperature, meaning that it would be perfectly conduct electricity.

如果我们能够弄清楚如何制造种物质，它将非常有用：据认为金在室温下会是超导体， 意味着它可以完美地传导电力。

Teams of researchers all over the world have been trying and failing to make metallic hydrogen for decades.

世界各地研究团队几十年来一直在尝试制造金，但都未能成功。

See, the team coated their diamonds in aluminum oxide to keep them from breaking, and it’s possible that the shiny stuff they saw was metallic aluminum oxide, not metallic hydrogen.

你看，研究团队在钻石上涂了一层氧化铝以防止其破裂， 他们看到闪亮物质可能是金氧化铝， 而不是金。

In the meantime, we can’t say for sure that they’ve created metallic hydrogen.

与此同时，我们不能确定他们已经制造出了金。

And with it’s super-strong bonds, solid metallic hydrogen would also be a great way to store energy, which would make it a better rocket fuel than the fuels we use now, like liquid hydrogen and oxygen.

由于其超强键合，固态金也将成为储存能量好方法， 将使其比我们现在使用液和液氧等燃料成为更好火箭燃料。

So the researchers announced these results in the paper published last week: they’d created solid metallic hydrogen.

所以研究人员在上周发表论文中宣布：他们制造出了固态金。
