  • The moon has always been an intimate part of humanity's existence.

    月亮一直是人類生存的親密組成部分。

  • You can see it from anywhere on earth and the effect that it's had on our planet and culture is beyond significant

    你可以從地球上的任何地方看到它 它對我們的地球和文化所產生的影響是無比巨大的。

  • But hypothetically, what would happen to us if we destroyed the whole thing?

    但是假設,如果我們毀掉了這一切,我們會怎麼樣?

  • In 1958 the Soviet Union was beating America in the race to space.

    1958年,蘇聯在太空競賽中打敗了美國。

  • In response the United States developed a plan called Project A119.

    為此,美國製定了一項名為 "A119項目 "的計劃。

  • Which involved detonating a nuclear bomb on the moon's surface.

    其中包括在月球表面引爆一枚核彈。

  • Knowing the explosion would be visible to people worldwide, the US government believes project A119

    美國政府知道爆炸會被全世界的人看到,是以認為A119項目。

  • would provide both a morale boost to the American people and a show of force to intimidate the Soviet Union

    既能鼓舞美國人民的士氣,又能展示武力,威懾蘇聯。

  • Thankfully the plan was scrapped in favor of landing actual people on the moon

    幸運的是,這個計劃被取消了,改為讓實際的人登陸月球。

  • But nuclear weapons wouldn't really be enough to destroy the moon anyway.

    但無論如何,核武器都不足以摧毀月球。

  • To even come close, we would have to detonate an explosive up to several billion times more powerful than the entire nuclear arsenal of the world.

    要想接近,我們就必須引爆比世界上整個核武庫強大幾十億倍的爆炸物。

  • Which means that destroying the moon is currently impossible.

    也就是說,摧毀月球目前是不可能的。

  • But assuming that we developed some amazing

    但假設我們開發了一些驚人的

  • destructive technology in the future and annihilate the moon,

    未來的破壞性技術,消滅月球。

  • what would happen to us here on Earth?

    我們在地球上會發生什麼?

  • First, if the moon shattered into tiny little pieces

    首先,如果月球碎成一小塊一小塊的話

  • they might eventually coalesce into a brilliant ringed system around our planet

    它們可能最終會在我們的星球周圍凝聚成一個燦爛的環狀系統。

  • Fragments of the moon would frequently rain down onto the Earth's surface like meteorites

    月球的碎片會經常像隕石一樣落到地球表面。

  • but not as destructive.

    但破壞性不強。

  • While some meteorites hit Earth at speeds of over 100 kilometers per second

    而有些隕石以每秒100多公里的速度撞擊地球。

  • these lunar fragments would only be traveling at a fraction of that, around 8 kilometers per second

    這些月球碎片的速度只有其中的一小部分,大約每秒8公里

  • so their damage could be pretty bad, but not entirely catastrophic.

    所以他們的傷害可能很嚴重,但不完全是災難性的。

  • Without the moon obscuring light from less bright objects,

    如果沒有月亮遮擋住不太亮的物體的光線。

  • more stars would be visible from Earth's surface and night skies would be significantly brighter

    從地球表面可以看到更多的恆星,夜空也會明顯變亮。

  • which would hopefully be a consolation for not being able to witness a solar eclipse ever again.

    這將有望成為再也無法目睹日食的安慰。

  • Of course without the moon, the tidal forces on the world's oceans and lakes would drop dramatically as well

    當然,如果沒有月亮,世界海洋和湖泊的潮汐力也會急劇下降

  • Tides wouldn't completely go away because the Sun also exerts a tiny force on them,

    潮汐不會完全消失,因為太陽也會對潮汐施加微小的力量。

  • but they would drop to about 25% of their current levels.

    但他們會降到目前水準的25%左右。

  • Surfing as a sport would be severely less cool and

    衝浪作為一項運動,將嚴重減少酷和。

  • coastal communities would have to adapt to lives with a far smaller tides than usual.

    沿海社區將不得不適應比平時小得多的潮汐的生活。

  • However, perhaps the most catastrophic effect that would happen without a moon

    然而,也許最災難性的影響,將發生在沒有月球的地方

  • would be the extreme change in Earth's axial tilt.

    將是地球軸向傾斜度的極端變化。

  • Earth spins on its axis currently at 23.4 degrees.

    地球自轉軸目前為23.4度。

  • Over a period of tens of thousands of years however that tilt varies between

    然而,在數萬年的時間裡,這種傾斜度卻在不同的地方變化。

  • 22.1 degrees to 24.5 degrees.

    22.1度到24.5度。

  • The moon acts as a stabilizing force on this tilt keeping it between these values

    月亮作為一個穩定的力量,對這個傾斜保持它之間的這些值

  • But without it this stability would be lost forever.

    但如果沒有它,這種穩定將永遠失去。

  • Earth's tilt could exceed 45 degrees at times in this scenario spinning on its side.

    在這種情況下,地球的傾斜度有時可能會超過45度,側身旋轉。

  • This would be very weird to get used to over time,

    這樣久而久之就會很奇怪,習慣了。

  • because the poles wouldn't necessarily always be cold places

    因為兩極不一定都是寒冷的地方。

  • and the equator wouldn't necessarily always be a warm place.

    而赤道也不一定永遠是個溫暖的地方。

  • Imagine the extreme changes that would happen if all the ice in Antarctica

    想象一下,如果南極洲的冰層全部消失,會發生怎樣的極端變化?

  • melted and exposed a new continent open to human settlement

    融化後,露出了一塊新的大陸,供人類居住。

  • or if the equator began to be a region that got regular snow and ice of their own.

    或者說,如果赤道開始成為一個有自己固定冰雪的區域。

  • Ice ages would hit different parts of the planet at different times every few thousands of years

    每隔幾千年,冰河時代就會在不同時間襲擊地球上的不同地方

  • but that's the thing,

    但這是事情。

  • these changes wouldn't be immediate and you wouldn't notice much of a change in your lifetime

    這些變化不會是立竿見影的,在你的一生中也不會有太大的變化。

  • But fast-forward maybe 5,000 years into the future and Earth could be totally unrecognizable,

    但是,快進到也許5000年後的未來,地球可能完全無法辨認。

  • which in a geological timeframe is basically instant

    在地質時間上基本上是瞬間的事情

  • Sure, moon fragments would probably rain down to our surface and cause some damage

    當然,月球碎片很可能會落到我們的表面,造成一些破壞

  • and the severe reduction in tides would be weird for some people to get used to,

    而潮汐的嚴重減少對一些人來說會很奇怪,不習慣。

  • but if the moon were to be destroyed it would not cause an instant apocalypse.

    但是,如果月球被摧毀 它不會導致一個瞬間的啟示。

  • The real damage to our planet wouldn't be obvious until far into the future

    對我們星球的真正破壞要到未來才會顯現出來

  • Perhaps the most terrible part about destroying the moon for us in the present,

    也許對於現在的我們來說,毀掉月球是最可怕的。

  • would be robbing us of our stepping-stone out into the rest of the universe.

    會剝奪我們進入宇宙其他地方的踏腳石。

  • Fate and circumstance gave civilization on Earth an incredible gift in the moon

    命運和環境給了地球文明一個不可思議的禮物,那就是月球。

  • A practice test nearby to home, for space missions and a natural launch pad into the rest of the solar system.

    在家附近的練習測試,為太空任務和進入太陽系其他地方的天然發射臺。

  • Without it, this natural advantage would be permanently lost, but thankfully since we live in reality

    如果沒有它,這種天然的優勢就會永久失去,不過幸好因為我們生活在現實中

  • and we won't actually destroy it we may take advantage of it again soon.

    我們不會真正的摧毀它 我們可能很快又會利用它。

  • If you want to take advantage of your own stepping stone towards a new project or business

    如果你想利用自己的墊腳石,走向一個新的項目或業務。
