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

人们认为木星的大部分是金属氢组成的。

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，你就会发现金属氢，是一直存于地核中的物质。

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

相当于地球表面数百万倍的大气压、约 1 万摄氏度的环境下，氢会转变成一被称为“金属氢”的状态。

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.

金属氢具有高反射性，因此尝试用光看看下面，是不可能的，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大几倍的岩石内核，被冰层和奇特的金属氢所包围。

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

液态金属氢构成了木星内部的大部分。

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

木星形成时仍然是温暖的，它的内部主要是金属性氢，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.

40,234 （2万5千英）的深度，它会受到强烈的压缩，变得比岩石更硬，密度更大，变成所谓的金属氢。

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，来自金属氢的浮力，抵消掉向下的重力。

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

氢分子被紧紧地压一起，从而使电子挣脱形成一叫做金属氢的特殊物质。

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

发生的最大变化是，金属氢现具备了导电的能力。

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

我们向液态金属中注入高温氢等离子体。

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

金属氢将开始形成， 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.

上周发表于《科学》杂志的一篇论文中，两位来自哈佛大学的研究人员宣布， 他们完成了物理学家80年来一直试图做到的事情：他们制造出了固态金属氢。

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物质，它将非常有用：据认为金属氢室温下会是超导体， 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.

世界各地的研究团队几十年来一直尝试制造金属氢，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，研究团队钻石上涂了一层氧化铝以防止其破裂， 他们看到的闪亮物质可能是金属氧化铝， 而不是金属氢。

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属氢。

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.

于其超强的键合，固态金属氢也将成为储存能量的好方法， 将使其比我们现使用的液氢和液氧等燃料成为更好的火箭燃料。

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

所以研究人员上周发表的论文中宣布：他们制造出了固态金属氢。
