  • Oxygen is the third most abundant element in the universe,

    氧是宇宙中豐度排行第三的元素

  • allowing us to breathe, construct materials, and do a lot more than you might realize.

    它的存在讓我們能夠呼吸、建構物質、以及其他你可能根本沒想到的事

  • So what would happen if it disappeared from the earth for 5 seconds?

    如果地球上的氧氣突然消失五秒會發生什麼事呢?

  • If we first look at the loss of atmospheric oxygen as an oxygen in the air,

    如果我們講的是空氣裡少了氧氣的這種情況

  • you may not want to be traveling.

    你大概不會希望你剛好在旅行的途中

  • Without oxygen, the internal combustion engines found in 250 million vehicles in the US alone

    沒有了氧氣,全美 2.5 億輛交通工具裡的內燃機

  • would be unable to turn heat into the work required to push the piston inside.

    就無法將熱能轉成推動內部活塞所需要做的功

  • Cars would most likely not start and if already moving would stop running immediately.

    當然車子也就無法發動,而已經發動的車子也會馬上停止運行

  • Considering that an estimated 100 airplanes take off or land every minute,

    每一分鐘估計大約有 100 架飛機起飛及降落

  • the loss of oxygen could also cause some early crash landings all over the world.

    沒有了氧氣也可能造成各地的飛機緊急迫降

  • Although airplanes already in the air could probably glide safely until oxygen returned.

    雖然航行中的飛機應該是可以安全地滑行直到氧氣回復

  • But would you suffocate?

    那你會因為沒有氧氣而窒息嗎?

  • Oxygen does play a crucial role in one of the last steps of cellular respiration.

    氧氣在呼吸作用的最後階段扮演著很重要的角色

  • But luckily our bodies have alternative pathways that

    但幸好我們的身體有替代途徑

  • help us survive when we temporarily lack of oxygen.

    讓我們可以在短暫缺乏氧氣時仍可以存活

  • For example, during intense exercise, muscle cells will use up all of their oxygen and

    比方說在激烈運動時,肌肉細胞會耗光周圍的氧氣

  • switch to a process called lactic acid fermentation, which uses glucose to produce energy.

    並轉而行乳酸發酵,也就是用葡萄糖來產生能量

  • Cells lacking oxygen also have been shown to reprogram itself to prioritize and

    細胞缺乏氧氣時,它也會重新調整工作的優先順序

  • make the most necessary proteins first.

    優先製造最重要的蛋白質

  • All in all, if you can hold your breath for 5 seconds,

    總而言之,如果你可以憋氣五秒鐘

  • then you'll most likely survive the atmospheric oxygen apocalypse.

    你就可以從這場「無氧氣末日」中存活下來

  • But when we take the question literally,

    但如果我們從字面上來看待這個問題

  • as in what would happen if we lost the oxygen atom completely.

    那就是如果氧原子完全消失會發生什麼事?

  • Obliterating it from compounds like water, quartz, and ozone

    將氧原子從水、石英及臭氧等化合物中抽離

  • then the results become more devastating. If we consider non-living things alone, then

    所造成的結果會更具毀滅性。我們先談談那些非生物的情況

  • nearly everything in the material world would turn into a metallic dust when oxygen is done.

    只要缺乏氧原子,幾乎所有物質世界的東西都會變成金屬屑屑

  • This includes buildings, cars, roads, clothes, furniture, and more.

    像是建築物、車子、馬路、衣服、家具、和其他東西都難逃一劫

  • As all our materials like concrete, wood, glass, stone, brick and cotton

    所有物質像是水泥、木頭、玻璃、石頭、磚塊和棉花

  • all contain or are made up of an oxygen-based compound.

    都含有氧原子或是由氧原子的化合物所組成

  • Without the oxygen bond, many of these compounds would be

    少了跟氧原子的鍵結,很多化合物就只能

  • left with their elements unbound and in their simplest form.

    以他們最基本的形態存在

  • And while all your favorite stores in possessions turn to dust, they'll be simultaneously

    當那些你喜歡的東西都變成塵埃,它們也會同時

  • collapsing into the center of the earth, to be burned in a fiery oblivion.

    朝地球中心瓦解,並在一場大火中燃燒殆盡

  • As oxygen makes up 46% of the Earth's crust, the ground beneath us would cease to exist.

    因為地殼的有 46% 都是氧原子組成,所以當氧原子消失時,我們腳下的地面就會不復存在

  • The ocean which covers about 70% of the Earth would evaporate and become hydrogen gas.

    而佔據地球表面積 70% 的海洋將會蒸發並留下氫氣

  • And upon the return of oxygen 5 seconds later, the reaction between hydrogen and oxygen

    過了五秒鐘後,當氧原子又出現時,氫原子和氧原子便會反應

  • would release mass amount of heat as water is produced again.

    重新製造水,這個過程會釋放極大量的熱

  • So the world would end all around us.

    所以整個地球就會毀滅

  • But that's okay, you probably won't be around to witness any of this.

    但不要擔心,你大概也沒機會目睹這一切

  • As all our living cells contain water and will like

    我們所有的活細胞之中都含有水,也因此情況就會像剛剛

  • the ocean evaporate into space as hydrogen gas.

    海洋蒸發並以氫氣的形式逸散到太空中一樣

  • The rest of us would be dead as well with oxygen and hydrogen gone.

    少了氧原子和氫原子,我們也註定會面臨死亡

  • We've lost 75% of our elemental makeup and only a pile of carbon, nitrogen,

    因為我們會失去 75% 的主要組成成份,只剩下一堆碳、氮

  • calcium, phosphorus, and other trace elements would be what's left of our bodies.

    鈣、磷以及其他殘存在我們體內的微量元素

  • Without oxygen, it's safe to say you wouldn't feel so good.

    沒有了氧原子,我相信你絕對不會太好受

  • Thank you guys so much for watching.
