It's one of the most beloved astronomical scenarios of kooks, con-artists and Hollywood producers,
最受怪人、骗子和好莱坞制片人欢迎的天文场景之一
A planetary alignment: when the planets line up with the sun to form a sort of celestial Newton's Cradle
就是行星联珠，即行星与太阳连成一线，形成天体牛顿摆，
and the Laws of Physics presumably use the Solar System as a little plaything.
物理定律大概把太阳系当成了一个小玩物。
You've probably seen this scenario in a movie or read one of the conspiracy theories online.
你可能在电影中看过这样的场景或阅读过网上的阴谋论。
The gravitation of the aligned planets would cause a catastrophic force
连成一线的行星引力将带来灾难性的力量，
causing earthquakes and tsunamis on Earth,
导致地球发生地震和海啸，
throwing other planets out of their orbits and probably other bad stuff.
把其他行星扔出轨道，也可能导致其他糟糕事件的发生。
Well, obviously, this Mayan apocalypse version of events has never come to pass.
显然，这一玛雅世界末日版本的事件从未发生过。
But there are conflicting opinions about whether a true planetary alignment has ever happened.
但对于行星联珠是否真正发生过，人们意见不一。
Some scientists think it just might not be possible, at least not precisely
一些科学家认为它不太可能发生，至少不可能那么精确得排成一线，
because the planets don't travel on the same exact plane.
因为行星不在同一平面上运行。
It's true that most of them travel at roughly the same level as they orbit the sun, an area known as the ecliptic
的确，大多数行星在绕太阳公转时几乎都在同一水平面，即被称为黄道的区域上。
but Mercury dips a little above and below that line.
但水星在那直线或高或低的位置。
And Pluto is NOT a planet.
而且冥王星不是行星。
But if we were making a Sci-fi adventure movie in the 80's and we wanted to cast Pluto,
但如果我们在80年代制作科幻冒险电影，想要算上冥王星的话，
its orbit is so rogue and weird it would never fall in line.
它的轨道很怪异，从不落在行星连线上。
Other astronomers though argue that in the four and a half billion or so years that the planets have been around,
其他的天文学家认为大约四十五亿年前行星就已经存在了，
they've probably fallen into a line at least a couple of times.
它们可能至少有几次连成一线。
The thing is, even though we have a pretty good handle on the planets' orbits,
问题是，即使我们能很好地控制行星轨道，
there doesn't seem to be a single agreed upon calculation about
似乎也没有一个人同意计算
how often all eight of them will line up closely in three dimensions.
它们8个多久会在三维空间中紧密排列。
To give you a sense of how hard it is for these eight little ducks to fall in a row,
为了让你对8颗行星连成一线多难有个感知，
it's kind of a big deal when the planets are simply all on the same side of the sun.
当行星都在太阳同一边时就显得格外重要了。
That happened in March of 1982, for example,
比如，这事在1982年3月发生过，
and a few hucksters managed to sell copies of their book by claiming a so called "Jupiter Effect"
还有一些小贩通过声称所谓的“木星效应”来销售他们的书，
would cause all sorts of catastrophe on Earth, especially to poor California.
“木星效应”会带来地球上的各种灾难，特别是可怜的加利福尼亚。
Now, I wasn't born yet, but Hank was and he's fine so no "Jupiter Effect" in 1982.
那时，我还没出生，但汉克出生了，他现在没事，所以1982年没有“木星效应”。
In May of 2000, meanwhile, Mercury, Venus, Mars, Jupiter and Saturn all happened to fall into the same slice of the Solar System, about twenty-five degrees across.
与此同时，在2000年5月，水星，金星，火星，木星和土星恰巧落在太阳系同一面，形成大约25度的倾斜角。
But we couldn't see it, because they were all on the other side of the sun.
但我们没有看到，因为它们在太阳的另一边。
Even if all of the planets were to line up with the sun in true Hollywood fashion, nothing would happen to Earth.
即使所有行星都以真正好莱坞的方式与太阳排成一线，对地球也没影响。
Space is big and the planets are small and really far apart.
太空很广，行星很小，距离也很远。
The vast majority of the gravitational effect felt by Earth is from the moon and the sun.
地球所受的大部分引力作用来自于月球和太阳。
Everything else is negligible.
其他的可忽略不计。
We can look at it this way: the sun exerts less than half of the tidal force that the moon does.
我们可以这样看:太阳的潮汐力不到月球的一半.
And the next biggest object in the Solar System, Jupiter exerts only 0.001% percent of the force that the sun does.
而太阳系的第二大天体木星所产生的力只有太阳的0.001%。
In 2000, NASA actually did the math and calculated that
2000年，美国宇航局实际做了数学计算，
even if all of the planets and moons in the Solar System were lined up precisely with Earth,
并计算出即使太阳系所有的行星和卫星都与地球精确对齐，
it would exert enough extra gravitation to raise the ocean tides by 1/25 of one millimeter,
它产生的额外引力只会使海洋潮汐上升1/25毫米。
which I think could be an interesting movie but definitely more of a Terrence Malick than a Michael Bay.
我认为这可能是一部有趣的电影，但肯定是泰伦斯·马力克的拍摄风格，而不是迈克尔·贝的。
But you know what would be an amazing movie with at least some appeal?
但你知道什么是有吸引力的好电影吗？
Syzygy: when three or more celestial bodies align.
朔望，即三个或三个以上的天体连成一线。
This is a lot more common because it involves fewer moving parts,
这很普遍，因为它包含较少的活动天体，
so it's easier for us to predict and understand.
所以我们更容易预测和理解。
Every time we can see a solar or lunar eclipse from Earth,
我们每次从地球上看到的日食和月食，
that's a type of syzygy involving the sun, the Moon and our home planet.
都是包含太阳、月球和地球的朔望。
Which is swell, but there are practical applications too!
它很漂亮，但也有实际的应用！
In 1966, engineers of the jet propulsion laboratory discovered
1966年，喷气推进实验室的工程师们发现
that Jupiter, Saturn, Uranus and Neptune would align in syzygy 13 years later in 1979.
木星、土星、天王星和海王星将在13年后的1979年连成一线形成朔望。
So, NASA used that math to plot the course of the Voyager 1 and 2 spacecraft
所以，美国宇航局利用数学绘制了旅行者1号和2号宇宙飞船的航线
allowing them to study all four planets as they passed by, giving us our best look yet at the outer Solar System.
允许它们研究经过的四颗行星，这让我们对外太阳系有了最佳的了解。
Not only did the disaster not happen, but something really, really awesome happened.
不仅没有发生灾难，而且发生了一些了不起的事！
You guys would watch that movie, right?
你们会看那部电影的，对吧？
