人类不能死皮赖脸在地球住一辈子吧
The planet earth isn't going to be habitable forever
如果人类想活命
if the human race is going to survive
迟早得收拾东西搬家
one day will have to pack up our things and move to another planet,
你不了解宇宙的浩瀚，你也不了解太阳系有多大，搬家很难
it sounds easy until you realize the vastness of space and even how big our Solar system is
甭管我们搬到哪里去，我们都需要超光速旅行
no matter where we're going in space, we need to travel fast and not just at the speed of light either,
对的，我们正在谈论：狂暴超光速，这速度很危险
we're talking about you ludicrous speed.
一些科学怪人儿已经设计出了违反物理学定律的狂飙引擎
But some researchers have designed an impossible engine that violates the laws of physics
其他人儿说：曲率引擎是可以实现的！（笔者完全同意！）
and another group of scientists are now saying a warp drive is possible
因为NASA真的在研究这些反人类引擎么。对于宇宙旅行这到底好使么？
Is NASA really working on this technology and what does the future hold for space travel ?
你寻思一下
Consider this for a moment
我们的邻居：半人马座阿尔法星距离我们4.367光年那么远
a closest neighbor Alpha centauri is four point three six seven light-years away
就算我们坐船以100%光速前进
So even if we travelled in a ship at one hundred percent light speed
估计得4.36年才能到站
it would still take you four point three six seven years to get there
我们现在只能坐火箭
We could use rockets to get ourselves around in space
但是火箭的油箱太沉了，而且限号不让开！
but the big problem with them is the amount of fuel you need to carry to get anywhere,
而且，火箭的推力是有极限的，推力太猛容易爆哦。
but even rockets have their limits including how fast they can push a spacecraft.
我们得弄个反人类引擎，既能提供强大推力，又能少携带燃料，或者不需要燃料了
We're going to need something that can generate some serious thrust and be able to do so without carrying a large amount of fuel
因为，宇宙空间没有中石化，中石油！加油站
because in space there are no gas stations.
现在好了，有一种反人类引擎根本不需要燃料
But there is an engine out there that reportedly can push a spacecraft around without the need for fuel
更要命的是：还没有尾气排放！你就打火儿，挂挡，踩油门儿，松离合，开起来喽！
and this engine produces no exhaust, either, you just plug it in firing up and go,
这就是：EM永动机，反正它秒天秒地秒空气，啥都能干哈！
it's called the EM drive or impossible engine because it claims it can do the impossible.
这玩意儿从侧面看，还是个火箭发动机
So how does this PM drive work at first glance it actually does look a bit like a rocket engine from the side
但是，打开门儿一看：它是个微波炉
however there are openings in the device, and it works by bouncing around microwaves inside a closed chamber.
微波来回嘚瑟，撞击微波炉，所以就动了，反人类引擎诞生了！
That bouncing around if microwaves and the chamber is supposed to create a push so to speak.
但是，有bug，因为这有点不符合动量守恒定律
This is a big deal because all forms of rocketry requires some conservation of momentum.
你想推动别的人，就得有东西推你，你想获得知识，最好投币点赞关注
In order to put a spacecraft in motion, you've got a push off something
