  • Did you just reverse the intro?

    你是不是把前奏反過來了?

  • That was cool!

    太酷了!

  • The Universe is pretty awesome.

    宇宙是很厲害的。

  • With our limited understanding of the Universe, it is possible that it could keep going on forever, but it's also possible that it could end in a final cataclysmic event. 

    以我們對宇宙的有限理解,它有可能一直持續下去,但也有可能在最後的大災難事件中結束。

  • One such universe-ending theory is called The Big Crunch.

    其中一個這樣的宇宙終結理論被稱為 "大緊縮"。

  • You've heard of The Big Bang, right?

    你聽說過 "大爆炸 "吧?

  • Basically, The Big Crunch is like that, but in reverse.

    基本上,"大緊縮 "就是這樣的,不過是反過來的。

  • It's a hypothetical scenario where the Universe would eventually stop expanding like it currently is, and instead contract or collapse into itself, taking everything within the Universe with itessentially consuming itself.

    這是一個假設的場景,宇宙最終會停止像目前這樣的擴張,而是收縮或坍塌到自己身上,把宇宙中的一切都帶走......本質上是消耗自己。

  • Not only does that sound pretty heavy metal, but it would be, well, pretty much the end of life as we know it.

    這不僅聽起來很重金屬,但這將是,嗯,幾乎是我們所知道的生活的結束。

  • However, within this theory, rather than The Big Crunch simply being a dark, bitter end to everything, it could also be a new beginning of sorts.

    然而,在這一理論內,與其說《大緊縮》只是一切的黑暗、苦澀的結局,還不如說它可能是一種新的開始。

  • There's this idea that it could lead to another Big Bang, starting the process all over again.

    有這樣的想法,它可能會導致另一個大爆炸, 開始的過程中,所有重新開始。

  • You could have a virtually never-ending cycle of Big Bangs and Big Crunches, leading to a type of cyclical universe model where, instead of switching everything off, somebody just keeps pushing the reset button.

    你可以有一個幾乎永無止境的大爆炸和大緊縮的循環,導致一種週期性的宇宙模型,在那裡,有人不是關閉一切,而是不斷地按下復位鍵。

  • That's somewhat uplifting I guess, though it does beg the wholewhat's the point?” question.

    我想,這有點讓人振奮,雖然這確實引出了 "意義何在?"的問題。

  • Let's save the existential dread for later! Okay, this is Youtube! Just keep watching! Everything's fine!

    讓我們把生存的恐懼留到以後再說吧!好了,這裡是Youtube!繼續看吧!一切都會好起來的!

  • All of this is purely hypothetical, of course, because there are still things that we don't really know or completely understand about the Universe.

    當然,這一切都純屬假設,因為對於宇宙,我們還有很多東西沒有真正瞭解或完全瞭解。

  • One of these question marks is called dark energy, which is believed to be about 70% of the composition of the Universe.

    其中有一個問號叫暗能量,據信暗能量佔宇宙構成的70%左右。

  • Little is really known about dark energy other than that it's some sort of seemingly-invisible space force that's been thought to cause the acceleration of the Universe's expansion.

    關於暗能量,人們知之甚少,只知道它是某種看似不可見的空間力量,被認為會導致宇宙膨脹的加速。

  • Dark energy has been mostly thought of as a cosmological constant, which doesn't look good for The Big Crunch theory's validity.

    暗能量大多被認為是一種宇宙學常數,這對大緊縮理論的有效性並不看好。

  • If dark energy is indeed a constant, then the Universe probably wouldn't collapse into itself, but rather keep on expanding.

    如果暗能量真的是一個常數,那麼宇宙可能不會自我坍縮,而是不斷膨脹。

  • In fact, recent research that came out earlier this year may take us even further away from The Big Crunch theory.

    事實上,今年年初的最新研究,可能讓我們離大緊縮理論更遠了。

  • Using a combination of X-ray and ultraviolet data, astronomers have found evidence that dark energy may be getting stronger with time.

    利用X射線和紫外線數據的組合,天文學家發現了暗能量可能會隨著時間的推移而變強的證據。

  • By looking at and comparing the distances of quasarsdistant, super-bright black holes—, the researchers found that the universe's expansion rate was faster than expected based on models where dark energy was kept as a constant.

    通過觀察和比較類星體--遙遠的超亮黑洞--的距離,研究人員發現,基於暗能量被保持為常數的模型,宇宙的膨脹速度比預期的要快。

  • So, if dark energy really is getting stronger, it's way more likely that we would be looking at something called a Big Rip. F's in the chat please!

    所以,如果暗能量真的越來越強,我們更有可能看到的是一種叫做大撕裂的東西。哈拉時請用F的!

  • The Big Rip theory says that the Universe could keep on expanding to the point where it rips itself apart.

    大撕裂理論說,宇宙可以不斷膨脹,以至於把自己撕裂。

  • We're talking everything from planets, to people, to even atoms themselves getting torn apart by The Big Rip.

    我們說的是一切,從行星,到人,甚至原子本身都會被 "大裂縫 "撕碎。

  • This could be the case if dark energy gets stronger and wins the tug-of-war against gravity, which, based off of that recent research, seems to be like a possibility.

    如果暗能量變得更強,並在與引力的拉鋸戰中獲勝,就有可能出現這種情況,根據最近的那項研究,這似乎像是一種可能性。

  • Yay! The video is over but the existential dread is back on! Woo!

    Yay!視頻結束了,但是存在感的恐懼又開始了!嗚!

  • We're probably gonna be fine though for a very long time. Don't- Don't worry about it!

    我們可能會被罰款,雖然很長一段時間。別... 別擔心!

  • So are there any other questions about space that you want answered?

    那麼,關於空間的其他問題,你還有什麼想要解答的嗎?

  • Let me know in the comment section below, or tell me, what should I answer next?

    在下面的評論區告訴我,或者告訴我,接下來我應該怎麼回答?

  • Curious to know what would happen if Earth only had one season? Check out this video!

    很想知道如果地球只有一個季節會發生什麼?看看這個視頻吧!

  • There actually has sort of been an example of this over 200 years ago due to a volcanic eruption.

    其實在200多年前,由於火山噴發,也算是有過這樣的例子。

  • When a volcano erupts, it releases dust, ash, and sulfur into the atmosphere that could block solar rays and actually cool the planet.

    當火山噴發時,它會釋放出塵埃、火山灰和硫磺到大氣中,可以阻擋太陽光,並實際冷卻地球。

  • As always, my name is Blocko, this has been Life Noggin, don't forget to keep on thinking!

    一如既往,我的名字叫Blocko,這一直是生活中的Noggin,別忘了繼續思考!
