  • Hey there and welcome to Life Noggin.

    嗨,歡迎收看 Life Noggin。

  • Just the other day, I was exploring my world with Triangle Bob and we found a place my animator forgot to design.

    就在前幾天,我和 Triangle Bob 一起探索我們的世界,然後我們找到了一個動畫師忘記設計的地方。

  • The end of my world is just a big, scary cliff to nowhere!

    我的世界邊界是一個巨大,無邊無際的可怕懸崖!

  • But you can float around, so it's kinda cool.

    不過你可以浮在空中,所以還是挺酷的啦。

  • It did have me wondering though, what's at the end of your universe?

    這不禁讓我想知道,你們的宇宙邊界有什麼東西呢?

  • If we want to know what's at the end of the universe, we should start at the beginning.

    如果我們想知道宇宙邊界有些什麼,就必須從宇宙的起源開始。

  • There are many different ideas for how our universe began, but the most popular one is the Big Bang Theory.

    對於宇宙的起源有許多說法,其中最主流的學說就是「大霹靂」(註:Big Bang Theory 也是一部美國影集的名字)

  • Nope, guys get out of here!

    噢不是你們,你們出去啦!

  • The Big Bang Theory was first proposed in the 1920's, saying that the universe once started out super small.

    「大霹靂」在 1920 年代第一次被提出,它認為我們的宇宙在剛開始非常微小,

  • From its tiny beginnings, the universe stretched and expanded until it became as big as it is now.

    宇宙就從一開始的微小,一直不斷延展到現在的大小。

  • According to NASA, if we looked at the universe one second after the Big Bang, we would most likely see a 10-billion degree sea of particles, such as neutrons, protons, and electrons.

    根據 NASA 的說法,如果我們觀察大爆炸後一秒的宇宙,我們可能會看到溫度為 100 億 K (克氏溫標) 的大量粒子,如中子、質子和電子等。

  • That's really hot!

    那真的很熱呀!

  • As everything expanded and took up more space, it all cooled down.

    隨著宇宙不斷擴張,占據更多空間之後,萬物都冷卻下來。

  • Particles grouped together and formed atoms.

    粒子們聚集在一起,組成了原子。

  • These atoms gave birth to stars and galaxies and molecules, and eventually the universe was filled with all the planets, people, and lovable internet friends that you have today!

    這些原子構成了星體、星系和分子,最後形成了填滿宇宙的星球,以及居住其上的人類和你可愛的網友!

  • And that's not all.

    不只這樣。

  • Our universe could still be expanding and stretching, and might do so for a very long time.

    我們的宇宙目前仍有延展性,這個狀態可能還會持續一段很長的時間。

  • Maybe forever!

    或許是永遠呢!

  • It's all super cool to think about, but why is the Big Bang the leading theory?

    這些東西想像起來真的都很酷!不過,為何「大霹靂」是主流學說呢?

  • Do we have any proof?

    我們有任何證據嗎?

  • Well, around the same time that the Big Bang Theory was introduced, no guys!

    這個嘛,當「大霹靂」理論被提出後的這段時間─噢!你們!

  • Please get out of here!

    請先離開好嗎!

  • I'm not talking about you.

    我不是在講你們。

  • Edwin Hubble made an interesting observation.

    Edwin Hubble 做了一個有趣的觀察。

  • He noticed that other galaxies were moving away from us in all directions.

    他注意到其他星系正各自以不同方向遠離我們。

  • Not only that, but the farther apart galaxies were from us, the faster they would seem to be moving away.

    不僅如此,原先距離我們越遠的星系,遠離我們的速度看起來也越快。

  • Hubble's observation was so important because it showed that the universe is still expanding.

    Hubble 的發現非常重要,因為它證明了宇宙正在持續擴張。

  • If things are moving apart, it stands to reason they were once closer together.

    如果大家都在分離,那就證明了我們曾經是靠近的。

  • The discovery of the cosmic microwave background, or CMB for short, also helped give credit to the Big Bang Theory.

    而微波背景輻射 (或簡稱 CMB) 的發現,也有助於大霹靂理論的可信度。

  • Since the Big Bang says that our early universe was a very hot place that eventually cooled down, there should be leftover radiation.

    由於大霹靂理論表示我們的宇宙早期是個非常炎熱的地方,但最終冷卻了下來,因此宇宙中應該會有殘餘的輻射。

  • Robert Wilson and Arno Penzias were the first to find the radiation while they were building a radio receiver.

    Robert Wilson 和 Arno Penzias 在建置無線電接收器時首次發現這個輻射。

  • Since then, we've learned a lot about the CMB from missions such as NASA's Cosmic Background Explorer and the Wilkinson Anisotropy Probe.

    從那時開始,我們從 NASA 的衛星任務中認識了更多微波背景輻射的知識,這些衛星有「宇宙背景探測者」或「威爾金森微波各向異性探測器」等等。

  • We now know that CMB radiation is not only very cold, close to absolute zero in fact, but it's also pretty uniform throughout the universe.

    我們現在知道,微波背景輻射除了溫度非常接近絕對零度,在宇宙各處的性質也很一致。

  • This uniformity is why it makes sense that it all came from one place, like the Big Bang.

    這種一致性說明了這些輻射皆來自同一個地方,例如大霹靂。

  • So, if the universe is still expanding, what's at the end of it?

    所以,如果宇宙仍在持續擴張,那宇宙的盡頭有著什麼呢?

  • Well, we can't know for sure right now and there's a good chance that we never will.

    這個嘛,我們目前無法確定,而我們也絕不會有可能性去確認。

  • That's because the universe doesn't just seem to be expanding, but also getting faster as it does.

    那是因為宇宙不僅是看起來在擴張,也擴張得越來越快。

  • If it doesn't stop, we'll probably never be able to find a way to go fast enough to reach it, since we believe it's already expanding faster than the speed of light.

    如果它不停止,我們可能永遠無法找到足夠趕上它擴張速度的方法,因為我們認為它的擴張速度已經比光速還快了。

  • Maybe one day somehow we'll find out, but until then me and Triangle Bob are going to float in the nothingness.

    或許某天我們會找出探索邊境的方法,但在那之前我和 Triangle Bob 都要一直漂浮在虛無之中。

  • It's really calming!

    這裡真的很平靜!

  • Wait a minute...is that my dad?

    等等...那是我爸爸嗎?

  • So what do you think is at the end of the universe?

    你們覺得宇宙的盡頭是什麼呢?

  • Let me know in the comment section below!

    在下方留言區讓我們知道你的想法吧!

  • Curious to know if there are actual parallel universes?

    想知道現實中是否有平行宇宙嗎?

  • Check out this video!

    看看這部影片吧!

  • As always, my name is Blocko and this has been Life Noggin.

    如同以往,我是 Blocko,這裡是 Life Noggin。

  • Don't forget to keep on thinking!

    別忘記持續思考喔!

Hey there and welcome to Life Noggin.
