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。

Instead of a mantle, like terrestrial planets, Jupiter has a huge region made up of liquid metallic hydrogen.

不想类地行星有地幔，木星有一大块区域由液态等离子氢构成。

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

氢分子被紧紧地压在一起，从而使电子挣脱形成一种叫做金属氢的特殊物质。

Metallic hydrogen would be a huge deal.

金属氢将是一件大事。

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，因此尝试用灯光看看下面，是不可能的，并且它像石头一样稠密。

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。

If it did, it's possible it was eroded away by currents of hot metallic hydrogen early on in Jupiter's formation process.

如果有的话，它也可能在木星形成的早期就被灼热的金属态氢腐蚀掉了。

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。

Jupiter has a very strong magnetic field, no doubt due to all of that metallic hydrogen inside it coupled with its rapid rotation.

木星有一个很强的磁场，毫无疑问，这是由木星内部的所有金属态氢加上它的快速自旋造成的。

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的，它的内部主要是金属性氢，并且可能甚至可能没有内核。

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

与此同时，我们不能肯定地说它们已经产生了金属氢。

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）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。

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，你就会发现金属氢，这是一直存在于地核中的物质。

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.

看，该团队在他们的钻石上涂上氧化铝以防止它们破裂， 他们看到的闪亮物质可能是金属氧化铝， 而不是金属氢。

In 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.

在上周发表在《科学》杂志上的一篇论文中，哈佛大学的两名研究人员宣布， 他们已经完成了物理学家80年来一直试图做的事情：他们创造了固体金属氢。

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.

凭借其超强的键合力，固态金属氢也将成为储存能量的好方法， 这将使其成为比我们现在使用的燃料（如液态氢和液态氧）更好的火箭燃料。

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.

如果我们能弄清楚如何制造这种东西，那将非常有用：人们认为金属氢在室温下是超导体， 这意味着它可以完美导电。
