Hey there, welcome to Life Noggin!
大家好！欢迎来到脑洞大开的生命奇想！
Just the other day, I was having an intense debate with triangle bob on the speed of light.
就在前几天，我和三角鲍勃就光速展开了激烈的辩论。
I was so ready to drop some knowledge on him, but triangle bob did what he does best and ran away because he knows he was wrong.
我已经准备好向他传授一些知识了，但是三角鲍勃做了他最擅长的事情，跑掉了，因为他知道他错了。
He didn't go faster than the speed of light, but is that actually possible? What would even happen?
他没有超过光速，但这真的可能吗？会发生什么呢？
But before we get into it we teamed up with our friends at Firefox, who are all about speed to make this video possible.
但在我们开始之前，我们和火狐的朋友合作，他们都很关注速度，我们才做出了这个视频。
Firefox is the only major browser backed by a non-profit and the new Firefox lets you browse the internet twice as fast as before.
火狐是唯一一个由非盈利组织维护的主流浏览器，新的火狐可以更快地浏览互联网。
Download and see the new Firefox today. Fast for good. Now to start our exploration, just what is light exactly?
今天就去下载新版火狐浏览器吧。快就是好。现在开始我们的探索，到底什么是光？
Well it's what's often referred to as electromagnetic radiation in a certain range of wavelengths, typically based off of what we can see with our eyes but can include other radiation that is out of the range of what we can see.
这就是通常所说的，特定波长范围内的电磁辐射，通常是我们眼睛所能看到的，但也可能包括其他超出我们所能看到的范围的辐射。
It's made up of particles called photons and travels at a speed of about 300,000 kilometers per second in a vacuum.
它由称为光子的粒子组成，在真空中以每秒30万公里的速度传播。
To give you an idea of just how fast that is, if someone was moving at the speed of light, they could circumnavigate the equator about seven point five times in just about one second.
告诉你这有多快，如果有人以光速移动，那他可以在大约一秒内绕赤道7.5圈。
If superhero comics taught me anything, I'm a little worried the Earth might go back in time and I really hope that's not true, because then this video wouldn't exist.
如果说超级英雄漫画教会了我什么，我有点担心地球可能会回到过去，我真的希望那不是真的，因为那是这个视频还不存在。
Superheroes aside, can we go faster than light? Well, in a vacuum, that doesn't really seem to be the case.
撇开超级英雄不谈，我们能比光速还快吗? 在真空中，情况似乎并非如此。
However in different mediums like glass and water light travels at slower speeds.
然而，在不同的介质中，如玻璃和水，光以较慢的速度传播。
Due to its slower speed it is possible for some particles to beat light in a race when it's going through certain mediums.
由于光速较慢，一些粒子在经过某些介质时，有可能速度超过光。
In fact, when this happens Chernenko radiation can occur.
事实上，当这种情况发生时，契伦科夫辐射就会发生。
Named after Pavel Chernenko, this type of radiation can be seen as a bluish white glow in places like the pools of water that surround nuclear reactors.
这种辐射以帕维尔·契伦科夫(Pavel Chernenko)的名字命名。在核反应堆周围的水池等地方，这种辐射可以被视为一种浅蓝色的白光。
In these instances, electrons from the reactors are moving through the water faster than light is moving through the water, creating what we see as the faint blue glow.
在这些情况下，反应堆中的电子在水中运动的速度比光在水中运动的速度快，形成了我们所看到的微弱的蓝光。
It's similar to a sonic boom, but with light instead of sound.
它类似于音爆，但这里是光，不是声音。
Going faster than light in this way is kind of like having Usain Bolt wear iron boots so that you can beat him, but hey, a win's a win.
以这种方式跑得比光速还快，有点像让尤塞恩·博尔特穿上铁靴子，这样你就能打败他了。不过赢家就是赢家。
It's also interesting to know that a few years ago, researchers in Scotland were able to slow the speed of light traveling through free space.
有趣的是，几年前，苏格兰的研究人员能够减慢光在自由空间中传播的速度。
Like we said before, we already knew that light could be slowed when it moved through things like water and glass, but they found that they could slow photons moving through free space.
就像我们之前说过的，我们已经知道光在水和玻璃等物体中运动时可以放慢速度，但是他们发现可以减慢光子在自由空间中的运动速度。
They did this by applying a mask to an optical beam that gave photons a spatial structure to reduce their speed.
他们通过给光束应用掩模来实现这一目的，光束给了光子一个空间结构。
While the difference they were able to measure was small hopefully this could lead to some pretty awesome discoveries one day, and help us better understand light.
虽然他们能够测量到的差异很小，但希望这能在某一天带来一些非常棒的发现，并帮助我们更好地理解光。
But just for fun, if we could find a way to travel at the speed of light, what are some things that might happen?
但问个有趣的问题，如果我们能找到一种以光速旅行的方法，会怎么样？
Well, there would probably be some complications like running out of fuel rather quickly or having a hard time avoiding space debris when going at that high of a speed.
嗯，可能会有一些复杂的情况，比如燃料很快耗尽，或者在以如此高的速度飞行时很难避开太空碎片。
Also due to time dilation, if you went on a mission in space going at the speed of light, when you got back to earth, your loved ones relative to you would have aged more.
同样由于时间膨胀，如果你在太空中以光速飞行，当你回到地球时，你的爱人相对你来说会很老。
If you did it for long enough, they could even be dead and that's pretty scary to think about.
如果你光速旅行的时间足够长，他们甚至可能死亡，这是非常可怕的。
Let's move on. If we could travel at the speed of light, it would certainly open us up to some amazing opportunities.
我们继续。如果我们能以光速旅行，它肯定会为我们带来一些美好的机会。
Besides just being able to get to school or work on time, we'd be better equipped to try and colonize other worlds.
除了能够按时上学或工作，我们还能更好地尝试开拓其他世界。
Going at the speed of light, we could reach Mars in under 30 minutes.
以光速飞行，我们可以在30分钟内到达火星。
We could also reach Trappist-1 in the span of one of our lives as it would only be about 39 years away.
我们也可以在生命的某一段时间内到达Trappist-1，因为只有39年的时间。
If you haven't heard of Trappist-1 yet, it's a planetary system with the most Earth-sized planets found in a habitable zone of a single star.
你可能还没有听说过Trappist-1，它是一个行星系统，在单个恒星的宜居带中发现了一些地球大小的行星。
Finding a way to get there could be a great leap for humanity expanding itself to other worlds.
找到一种到达那里的方式，可能是人类向其他世界扩张的巨大飞跃。
If you could travel at light speed, where would you go?
如果你能以光速旅行，你会去哪里?
