月亮与人类生存息息相关
The moon has always been an intimate part of humanity’s existence.
你能感受到月亮无处不在
You can see it from anywhere on earth and the effect
对于我们的星球和文化无比重要
that it’s had on our planet and culture is beyond significant
但假如我们毁掉整个月球会发生什么呢?
But hypothetically, what would happen to us if we destroyed the whole thing?
1958年苏联在太空竞赛中打败了美国
In 1958 the Soviet Union was beating America in the race to space.
作为回应 美国制定了一个叫做A119的计划
In response the United States developed a plan called Project A119.
包括在月球表面投放核弹
Which involved detonating a nuclear bomb on the moon’s surface.
因为世界各地的人都可以看到爆炸
Knowing the explosion would be visible to people worldwide,
所以美国相信A119计划
the US government believes project A119
既可以鼓舞美国人的士气
would provide both a morale boost to the
又可以向苏联展示威慑力
American people and a show of force to intimidate the Soviet Union
所幸由于要支持人类登月
Thankfully the plan was scrapped in favor
这个计划最终被废除
of landing actual people on the moon
不过要想用核弹来毁掉月球其实是不足够的
But nuclear weapons wouldn’t really be enough to destroy the moon anyway.
要想将月球几近毁灭 我们必须要制造出
To even come close, we would have to detonate
相当于全球所有核武器库威力的
an explosive up to several billion times more powerful than
数十亿倍的爆炸
the entire nuclear arsenal of the world.
这也就意味着毁掉月球目前是不可能的
Which means that destroying the moon is currently impossible.
但假设人类在未来发明出了更具杀伤力的技术
But assuming that we developed some amazing destructive technology
并且将月球湮灭
in the future and annihilate the moon,
那么对地球上的我们有什么影响呢?
what would happen to us here on Earth? First,
首先 如果月球被打碎成小块
if the moon shattered into tiny little pieces
最后他们可能结合在一起
they might eventually coalesce
成为围绕我们星球的明亮环形系统
into a brilliant ringed system around our planet
月球的碎片将像陨石一样
Fragments of the moon would frequently rain down
频繁地降落到地球的表面
onto the Earth’s surface like meteorites
但不具有毁灭性
but not as destructive.
一些陨石会以超过每秒100公里的速度撞击地球
While some meteorites hit Earth at speeds of over 100 kilometers per second
但这些月球碎片仅仅只是一小部分
these lunar fragments would only be traveling at a fraction
大约每秒8km
of that, around 8 kilometers per second
所以损失可能会有点大 但不是灾难性的
so their damage could be pretty bad, but not entirely catastrophic.
没有月亮掩盖其它较暗的发光体
Without the moon obscuring light from less bright objects,
我们可以在地球表面看到更多的星星
more stars would be visible
夜空会明显变得更加明亮
from Earth’s surface and night skies would be significantly brighter
这可能是对我们再也无法看到日食的一个安慰
which would hopefully be a consolation for not being able to witness a solar eclipse ever again.
当然 没有了月亮
Of course without the moon,
海洋和湖泊的潮汐力也将显著降低
the tidal forces on the world’s oceans and lakes would drop dramatically as well
但是潮汐力不会完全消失
Tides wouldn’t completely go away
因为太阳也对它们施加了微小的引力
because the Sun also exerts a tiny force on them,
但潮汐力会下降到目前水平的25%左右
but they would drop to about 25% of their current levels.
炫酷的冲浪运动也会大打折扣
Surfing as a sport would be severely less cool and
沿海社区必须适应
coastal communities would have to adapt to lives
潮汐比平常小得多的生活
with a far smaller tides than usual. However,
然而没有月亮而导致的
perhaps the most catastrophic
最具灾难性的影响也许就是
effect that would happen without a moon
地轴倾角的巨大变化
would be the extreme change in Earth’s axial tilt.
地轴倾角目前为23.4度
Earth spins on its axis currently at 23.4 degrees.
然而在几万年间
Over a period of tens of thousands
它在22.1度与24.5度之间不断变化
of years however that tilt varies between 22.1 degrees to 24.5 degrees.
月亮施加的稳定力量
The moon acts as a stabilizing force
使倾角保持在这些值的范围之内
on this tilt keeping it between these values
但没有了月球 这种稳定性将不复存在
But without it this stability would be lost forever.
地轴倾角有时可能超过45度
Earth’s tilt could exceed 45 degrees at times
在这种情况下旋转它的侧面
in this scenario spinning on its side.
随着时间的推移 这将会出现奇怪的情况
This would be very weird to get used to over time,
因为两极将不一定再是永远天寒地冻
because the poles wouldn’t necessarily always be cold places
而赤道也不一定总是常年炎热
and the equator wouldn’t necessarily always be a warm place.
想象一下会发生的极端变化
Imagine the extreme changes that would happen
如果所有在南极洲的冰
if all the ice in Antarctica
融化并暴露了一块开放的新大陆
melted and exposed a new continent open to human settlement
或者赤道开始成为一个
or if the equator began to be a
常年冰雪覆盖的地区
region that got regular snow and ice of their own.
冰河时期将每隔几千年
Ice ages would hit different parts of the planet
袭击地球的不同部分
at different times every few thousands of years
但事情就是这样
but that’s the thing,
这些变化不会马上发生
these changes wouldn’t be immediate and you
而你不会注意到你一生中的变化
wouldn’t notice much of a change in your lifetime
但也许快进5000年
But fast-forward maybe 5,000 years
未来地球将变得面目全非
into the future and Earth could be totally unrecognizable,
在地质时间表中基本上是一瞬间的事情
which in a geological timeframe is basically instant.
当然月球碎片很可能
Sure, moon fragments would probably
落到我们的表面并造成一些损害
rain down to our surface and cause some damage
潮汐的严重减少
and the severe reduction in tides would be weird
也会令人难以适应
for some people to get used to,
但是如果月亮被毁灭
but if the moon were to be destroyed
它不会立刻造成大灾难
it would not cause an instant apocalypse.
它对地球真正的危害
The real damage to our planet
直到很远的将来才会显现出来
wouldn’t be obvious until far into the future
或许月球的毁灭
Perhaps the most terrible part
给我们带来的目前最糟糕的事情
about destroying the moon for us in the present,
就是夺走了我们进入宇宙其它部分探索的一块跳板
would be robbing us of our stepping-stone out into the rest of the universe.
命运与环境给予了地球上的文明
Fate and circumstance gave civilization
一个位于月球的绝佳礼物
on Earth an incredible gift in the moon
一个毗邻家乡的航天任务实践测试点
A practice test nearby to home,
和一个进入太阳系其它地方的天然的发射平台
for space missions and a natural launch pad into the rest of the solar system.
失去月球 这个天然优势也就一去不复返了
Without it, this natural advantage would be permanently lost,
但幸运的是我们还生活在当下
but thankfully since we live in reality
我们并不会摧毁它
and we won’t actually destroy it
或许在不久的将来我们还会加以利用
we may take advantage of it again soon.
如果你想利用你自己的跳板
If you want to take advantage of your own stepping stone
