Hey there. Welcome to Life Noggin.
嘿，大家好。歡迎來到 Life Noggin。
The earth is huge. Its surface area is over 500 million square kilometers, and it currently holds over seven billion people. But it's nothing compared to the solar system which is billions of kilometers across. And that is still nothing compared to the Milky Way galaxy. And if we zoom out even more, we can really start to appreciate how huge the universe actually is. But we might be able to take this one step further because we might be living in something called a multiverse, where there is not just one universe but potentially a infinite amount of them. And if this is true, some scientists think that we have the Big Bang to thank.
地球很大。地球表面積超過五億平方公里，而且目前有超過七十億人居住於此。但地球跟橫越幾十億公里的太陽系一比就沒什麼了。跟銀河系一比更沒什麼。如果我們再把距離拉更遠一點，就真的會開始對宇宙的浩瀚無邊讚嘆不已。但我們也許可以再更進一步思考，因為我們可能住在一個所謂的「多重宇宙」中，也就是說宇宙不只一個，有可能是無限多個。如果這是真的的話，科學家認為這是大霹靂造成的結果。
See, for a fraction of a second after the Big Bang, the universe expanded incredibly quickly and then stopped. And over the next 14 billion years, it cooled down and formed stars, galaxies, and eventually—life. But there's reason to believe that there are some pockets of space that haven't stopped inflating and some others that have at different times. This is called the eternal inflation theory, and each of these bubbles of space forms its own isolated universe. And interestingly, the laws of physics and the fundamental constants might not be the same here.
在大霹靂發生後的瞬間，宇宙擴張的速度簡直快得嚇人，但一下子就停了。在接下來的一百四十億年中，宇宙冷卻並且形成恆星、星系，最終出現了生命。但仍有理由相信宇宙的某些地帶尚未停止膨脹，而且某些地域的時間並不相同。這就稱作「永恆膨脹論」，每個泡泡般的空間都形成自己的獨立宇宙。有趣的是，物理定律和基本常數可能會不盡相同。
And that got me thinking: What would a parallel universe even be like? Well, in a lot of these universes, you and I might not even exist. Sorry, sci-fi fans. I know that's hard to hear. See, if the laws of physics were different enough, like the forces between particles were too weak, atoms might never form. And that means no molecules, no stars and planets, and no life. Sounds pretty boring over there. Worst vacation spot ever.
這就讓我在想：平行宇宙會長什麼樣子？這個嘛，在許多這些宇宙空間之中，你我可能都不存在。抱歉喔，科幻迷們。我知道這很難接受。如果物理定律很不一樣的話，例如粒子之間的引力太弱，原子也許就永遠無法成形。那也意味著沒有分子，沒有恆星、行星也沒有生命。聽起來很無聊。最糟的觀光景點。
That said, there's also the possibility that the laws of physics in some of those universes are so close to ours that intelligent life is possible. And if there is an infinite amount of them, it's pretty likely that there's a bubble universe that is very similar to our own. Maybe in another universe, I'm really buff and strong. Okay, I'm not gonna get carried away.
不過，也有可能在那某些宇宙之中的物理定律跟我們的很相近，因此有可能存在有高度智慧的生命。如果宇宙的數量無限多的話，很有可能有個泡泡宇宙跟我們的宇宙很像。也許在另一個宇宙，我超壯的。好啦，我不要再亂蓋了。
And interestingly, it's theoretically possible that some of these neighboring universes can collide with each other. In fact, it's possible that our universe may have collided with others in the past. The main hypothesis is that a collision like this might have left a mark on the cosmic microwave background that we can detect. But sadly, the researchers haven't found anything so far, and there isn't any proof that parallel universes even exist. But if they do, and if they contain life, it would be interesting to see what that life was like.
有趣的是，理論上來說有可能這些鄰近的宇宙會彼此相互碰撞。事實上，我們的宇宙也許在過去和其他宇宙相撞過也說不定。主要的假說認為，這種爆炸會在宇宙微波背景上留下我們能察覺的痕跡。但很可惜地，目前學者尚未有任何發現，而且也沒有平行宇宙存在的證據。但如果平行宇宙真的存在，其中也有生命的話，看看那些生命的模樣一定會很有趣。
What do you think? Do you believe that parallel universes are out there? Let me know in the comments.
你怎麼想呢？你相信平行宇宙存在嗎？在留言處讓我知道吧。
