We'll be looking at questions about our wider universe that experts are still investigating which of these would you most like answered?

我們將關注專家們仍在研究的有關我們更廣泛的宇宙的問題，你最希望得到哪些答案？

Got any theories.

有什麼理論嗎？

Tell us in the comments Number 10.

在評論中告訴我們，10號。

A possible multiverse.

一個可能的多元宇宙。

The multiverse is a fun idea to contemplate and makes for some imaginative tales.

多重宇宙是一個有趣的想法，可以讓人思考，併產生一些富有想象力的故事。

The multiverse is a concept about which we know frighteningly little, but there may also be truth to the concept.

多元宇宙是一個我們知道得少得嚇人的概念，但這個概念也可能是真的。

The basic idea is that our universe might be one of many, perhaps even an infinite number.

其基本思想是，我們的宇宙可能是許多宇宙中的一個，甚至可能是一個無限的數字。

The existence of a multiverse has been proposed not only by philosophers but also physicists and cosmologists.

不僅是哲學家，物理學家和宇宙學家也提出了多重宇宙的存在。

If we could visit these other universes, we find that some might have basic properties of nature so far in that matter as we know it couldn't exist.

如果我們能訪問這些其他的宇宙，我們會發現有些宇宙可能具有基本的自然屬性，以至於我們所知道的物質不可能存在。

One suggestion is that it explains how our own universe seems to be fine tuned for conscious life in an infinite multiverse.

一個建議是，它解釋了我們自己的宇宙如何在無限的多元宇宙中似乎為有意識的生命進行了微調。

It's a sure bet that some of them will have the right initial conditions for the evolution of thinking beings.

可以肯定的是，其中一些會有合適的初始條件來進化出有思想的生物。

It's a bizarrely strange place, but scientists are still struggling to imagine.

這是一個奇異的地方，但科學家們仍在努力想象。

Some think it may even look a bit like this where each one of these stretched bubbles represents a universe as large and complex as ours.

有些人認為它甚至可能看起來有點像這樣，其中每一個被拉伸的氣泡都代表著一個像我們一樣大而複雜的宇宙。

Many scientists are skeptical of the idea, however, questioning whether it can ever be proven maybe our counterparts in a parallel world.

然而，許多科學家對這一想法持懷疑態度，質疑它是否能被證明也許我們在平行世界的同行。

Know the answer sounds about right, We don't talk about that, do we?

知道答案聽起來差不多，我們不談這個，是嗎？

No, we don't.

不，我們沒有。

Number nine Tabbies Star.

九號塔比星。

There are an estimated 100 to 400 billion stars in our galaxy, The Milky Way, but one in particular has captured the attention of the scientific community known as Tabbies Star.

在我們的銀河系中，估計有1000至4000億顆恆星，但其中一顆特別吸引了科學界的注意，它被稱為塔比星。

It's about 1470 light years away in the constellation cygnus.

它大約在1470光年之外，位於天鵝座。

It's basically a very weird star.

它基本上是一顆非常奇怪的星。

It's a very strange star.

這是一顆非常奇怪的星。

What this star show is something very, very large and very, very dark, appeared to be passing between us and the star.

這顆星顯示的是非常、非常大、非常、非常黑的東西，似乎在我們和這顆星之間經過。

It's not a planet because we know that it's not round and it doesn't orbit at a fixed period.

它不是一顆行星，因為我們知道它不是圓的，而且它的軌道沒有固定的週期。

The star mysteriously dims and brightens over time and the bizarre light fluctuations have baffled scientists often A drop in a star's light levels is a sign that a planet is passing in front of it.

這顆恆星隨著時間的推移神祕地變暗和變亮，奇怪的光線波動使科學家們常常感到困惑。 一顆恆星光線水準的下降是一個行星在它前面經過的信號。

But even a planet the size of Jupiter would only block about 1% of the light coming from a star like this.

但是，即使是木星那麼大的行星也只能阻擋來自這樣一顆恆星的大約1%的光線。

Several theories have been put forth, but no consensus has been reached.

已經提出了幾種理論，但沒有達成共識。

The theories in question range from a cloud of dust orbiting the star to space debris periodically obscuring the light.

有關理論包括從圍繞恆星運行的塵埃雲到定期遮擋光線的空間碎片。

Some scientists have even speculated that there's an alien mega structure involved, but if we're already invoking aliens in this explanation, then who's to say they didn't efficiently clean up all this mess for recycling purposes, maybe in a few years, we'll know the truth.

一些科學家甚至猜測有一個外星巨型結構參與其中，但如果我們在這個解釋中已經援引了外星人，那麼誰能說他們沒有有效地清理這些混亂的東西以達到回收的目的，也許在幾年後，我們會知道真相。

It's hard to study something so far away.

要研究這麼遠的東西是很難的。

Number eight jupiter's great red spot.

八號木星的大紅斑。

One of jupiter's distinguishing characteristics is undoubtedly its great red spot.

木星的一個顯著特徵無疑是它的大紅斑。

While it looks quite small within the context of the entire planet, the spot is Actually enormous.

雖然它在整個地球範圍內看起來相當小，但實際上這個點是巨大的。

The largest storm in the entire solar system with wind speeds up to 268 mph the giant red spot is over 10,000 miles wide, larger than the diameter of earth, but scientists studying the spot have noticed that it has been changing over time.

整個太陽系最大的風暴，風速高達268英里/小時，這個巨大的紅斑寬度超過10,000英里，比地球的直徑還要大，但是研究這個紅斑的科學家注意到，隨著時間的推移，它一直在變化。

The color is deepening, It's actually shrinking and getting rounder even more fascinating.

顏色在加深，它實際上在縮小，變得更圓潤，甚至更加迷人。

It's believed that the storm has been raging for at least 3.5 centuries on earth.

據悉，這場風暴在地球上至少已經肆虐了3.5個世紀。

Cyclones die when they hit land, but jupiter has no land to stop its storms, almost unlimited heat to fuel them and a rapid rotation.

旋風碰到陸地就會死亡，但木星沒有陸地來阻止它的風暴，幾乎有無限的熱量來推動它們，而且旋轉速度很快。

And yet we know very little about it.

然而我們對它知之甚少。

We don't really know what caused it, where it draws its incredible energy or why it's been going on for so long over the next couple of decades, it's believed the great red spot will shrink in longitude and become more circular.

我們真的不知道是什麼導致了它，它從哪裡汲取了令人難以置信的能量，或者為什麼它在接下來的幾十年裡持續了這麼久，據說大紅斑的經度會縮小，變得更加圓潤。

It could stay that way for many years.

它可以保持這種狀態很多年。

But if the GRS becomes too elongated, the jet streams could rip the anti cyclone apart.

但是，如果GRS變得過於細長，噴流可能會把反氣旋撕碎。

Heck, We don't even know for sure why it's red.

哎呀，我們甚至不知道為什麼它是紅色的。

Number seven missing.

七號失蹤。

Barry oneK matter, dark energy and dark matter make up 95% of the universe.

巴里一K物質、暗能量和暗物質構成了宇宙的95%。

The remaining 5% consists of visible or barry Onek matter.

剩下的5%由可見的或巴里-阿克物質組成。

Dark matter is believed to be an invisible stuff that interacts only through gravity.

暗物質被認為是一種看不見的東西，只通過引力進行互動。

It comprises 80% of the mass of the universe, or around 25% of its total energy content.

它包括宇宙品質的80%，或其總能量含量的25%左右。

The only thing is there should be way more barry onek matter around than there actually is.

唯一的問題是，周圍應該有比實際更多的巴里-歐克事件。

Studies have found a serious discrepancy in the amount of barry onek matter that existed after the Big Bang and the amount that surrounds today in the observable universe.

研究發現，大爆炸後存在的巴里一克物質的數量與今天圍繞在可觀察到的宇宙中的數量存在嚴重差異。

In fact, over half of this matter just seems to be missing.

事實上，這件事有一半以上的內容似乎就是沒有了。

So what the heck happened to the rest of it?

那麼，剩下的部分到底發生了什麼？

Scientists do have theories believing that some of this matter exists as difficult to detect hot strands between galaxy pairs or outside dark matter halos.

科學家們確實有理論認為，其中一些物質以難以探測的熱鍊形式存在於星系對之間或暗物質暈輪之外。

But research continues as measurements improve.

但隨著測量的改進，研究仍在繼續。

Number six alien life people just want to think that it's real.

第六號外星生命人們只是想認為它是真實的。

They want to think it's real, so bad that they are not looking at it completely objectively.

他們想認為這是真實的，以至於他們沒有完全客觀地看待它。

If it is real, we gotta know for sure.

如果它是真實的，我們必須確定。

It's perhaps the biggest question we all want an answer for.

這也許是我們都希望得到答案的最大問題。

Are we alone in the universe, mind you?

請注意，宇宙中只有我們嗎？

Extraterrestrial life could be as simple as a single celled organism.

地外生命可能簡單到只有一個單細胞生物體。

Extraterrestrial life.

地外生命。

You're right jerry.

你是對的，傑裡。

The people are gonna love it, but the odds do seem to be in favor of the idea of intelligent life out there somewhere to back in 1961 astronomer frank drake and his colleagues presented the drake equation, which attempts to estimate the number of communicative alien civilizations in our galaxy.

人們會喜歡它，但賠率似乎確實有利於智能生命在某處的想法，早在1961年，天文學家弗蘭克-德雷克和他的同事提出了德雷克方程，試圖估計我們銀河系中可交流的外星文明的數量。

The drake equation, however, is different because there are so many unknowns.

然而，德雷克方程是不同的，因為有這麼多的未知數。

It has no right answer as we learn more about our universe and our place within it.

隨著我們對我們的宇宙和我們在其中的位置有了更多的瞭解，它沒有正確的答案。

Some of the unknowns get better known and we can estimate an answer a bit better.

一些未知因素得到更好的瞭解，我們可以更好地估計一個答案。

Their original estimates where 1000 to 100 million, even conservative estimates often land in the thousands.

他們最初的估計是1億到1億，即使是保守的估計也往往是成千上萬。

Just imagine how many more could be out there in the wider universe beyond the Milky Way, number five, the size of the universe.

試想一下，在銀河系之外的更廣闊的宇宙中，可能還有多少人在那裡，五號，就是宇宙的大小。

There are many things we don't know about the universe we inhabit.

關於我們居住的宇宙，有很多事情我們不知道。

For example, its shape, although scientists think it's probably flat way way bigger.

例如，它的形狀，儘管科學家認為它可能是平的方式大。

So we're just we're just looking at a little piece and that's why it looks flat.

所以我們只是我們只是在看一小塊，這就是為什麼它看起來很平。

More interestingly, we don't know its true size.

更有趣的是，我們不知道它的真實尺寸。

Ever since the Big Bang 13.8 billion years ago, space has been constantly expanding.

自從138億年前的大爆炸以來，空間一直在不斷擴張。

In fact, space may expand faster than light controversy meaning that we will never observe parts of the universe beyond certain points.

事實上，空間的擴張速度可能比光的爭議更快，這意味著我們將永遠無法觀察到某些點以外的宇宙部分。

What we do know is the size of the observable universe comprising objects whose light has had time to reach our solar system.

我們所知道的是可觀察到的宇宙的大小，包括那些光線有時間到達我們太陽系的物體。

Not everything you can see in the night sky is actually in our galaxy.

不是所有你在夜空中看到的東西都是在我們的銀河系中。

It turns out that some of those faint dots are in fact other Galaxies.

事實證明，其中一些微弱的小點實際上是其他星系。

The furthest object you can see actually with the unaided eye is another galaxy called Andromeda and it's big 93 billion light years across the entire universe, maybe 250 times bigger than that.

實際上，你用肉眼能看到的最遠的物體是另一個叫仙女座的星系，它大的有930億光年，橫跨整個宇宙，也許比它大250倍。

Or it may simply stretch into infinity.

或者它可能只是延伸到無限大。

So the next time you stand gazing up at the night sky, take a moment to think about the enormity of what is beyond your vision.

是以，當你下次站在那裡仰望夜空時，請花點時間思考一下你視野之外的東西的巨大性。

Out in the dark spaces between the stars, number four, the fate of the universe.

在星星之間的黑暗空間裡，四號，宇宙的命運。

We have an idea about how the universe began with the Big Bang, but how will it end the answer?

我們有一個關於宇宙如何開始大爆炸的想法，但它將如何結束答案？

All depends on the universe's density.

這一切都取決於宇宙的密度。

If the universe is dance enough to counter expansion, the universe will contract in a big crunch.

如果宇宙的舞蹈足以對抗膨脹，那麼宇宙將在大緊縮中收縮。

One theory suggests that our universe will run out of steam and stop expanding every star, galaxy and planet.

一種理論認為，我們的宇宙將耗盡蒸汽，並停止擴張每一顆恆星、星系和行星。

Every atom will start to collapse, ending in a single super dense pinpoint, known as the big crunch.

每個原子都將開始坍縮，最後形成一個超級密集的針尖，被稱為大緊縮。

Some believe that afterwards a big bounce will occur with a new Big Bang emerging from the singularity.

有些人認為，之後會發生大反彈，從奇點中出現一個新的大爆炸。

In contrast, the big rip theorize is that the universe will continue to expand until tearing itself apart.

相比之下，大裂縫理論認為，宇宙將繼續膨脹，直到撕裂自己。

The big rip is one Cruising just above Earth's atmosphere and peering deep into space.

大裂縫是一個 遊弋在地球大氣層之上，向太空深處窺視。

The Hubble telescope provides scientists with clues to a less violent but equally unavoidable end of the universe.

哈勃望遠鏡為科學家提供了宇宙中不太激烈但同樣不可避免的結局的線索。

The leading theory is the big freeze in which continued expansion makes star formation impossible and the universe exhausts its finite source of energy cooling to absolute zero expansion wouldn't be able to accelerate anymore, but the universe would keep getting bigger clusters of Galaxies would separate the objects within the Galaxies, suns, planets and solar systems would move away from each other until Galaxies dissolved into lonely objects floating separately in the vast space.

最主要的理論是大凍結，在這種情況下，持續的膨脹使得恆星形成不可能，宇宙耗盡了其有限的能量來源，冷卻到絕對零度，膨脹將無法再加速，但宇宙將繼續變大，星系團將分離，星系內的物體、太陽、行星和太陽系將相互遠離，直到星系溶解成孤獨的物體，分別漂浮在廣闊的空間。

Number three.

三號。

Dark matter and energy.

暗物質和能量。

It's pretty astounding to think that dark matter and dark energy make up most of the universe and we really don't know anything about them.

想想看，暗物質和暗能量構成了宇宙的大部分，而我們對它們真的一無所知，這真是令人震驚的事情。

The question that's now obsessing astronomers including Michael Turner, is what dark energy might be.

現在困擾著包括邁克爾-特納在內的天文學家的問題是，暗能量可能是什麼。

So we just don't know what it is.

所以我們只是不知道它是什麼。

If it is the like Einstein's cosmological constant, then it's just the energy of nothing.

如果它是像愛因斯坦的宇宙學常數，那麼它就只是無的能量。

And according to quantum mechanics, Nothing is not nothing.

而根據量子力學，"無 "並不是 "無"。

We know that dark matter exists due to certain gravitational effects and dark energy, thanks to the fact that the universe's expansion is accelerating.

我們知道，暗物質的存在是由於某些引力效應和暗能量，這要歸功於宇宙的膨脹正在加速。

But what are they?

但它們是什麼？

One theory posits that dark energy is a fundamental energy intrinsic to space itself, scientists believe it makes up 85% of the matter in the universe and also controls the remaining 15% regular matter like stars, planets us.

一種理論認為，暗能量是空間本身固有的基本能量，科學家認為它構成了宇宙中85%的物質，也控制著剩下的15%的常規物質，如恆星、行星我們。

If they're right, dark matter played a critical role in actually building the universe we see today, dark matter, on the other hand, may consist of as yet undiscovered subatomic particles.

如果他們是對的，暗物質在實際構建我們今天看到的宇宙中發揮了關鍵作用，另一方面，暗物質可能由尚未發現的亞原子粒子組成。

But really, these are just our best guesses, since dark matter doesn't seem to interact with the electromagnetic field.

但實際上，這些只是我們最好的猜測，因為暗物質似乎並不與電磁場相互作用。

We have no way of directly observing it.

我們沒有辦法直接觀察到它。

It's ghost matter.

這是鬼魂的事。

It doesn't blow, it doesn't reflect light, But it adds to the gravitating mass of objects.

它不吹氣，不反射光線，但它增加了物體的引力質量。

And if such a clump of material passes through or near our solar system, its gravitational force could have a profound effect.

如果這樣的物質團塊經過或靠近我們的太陽系，其引力可能會產生深遠的影響。

# two before the Big Bang.

#大爆炸之前的兩個。

Um it's an interesting question because that's just repeat.

嗯，這是個有趣的問題，因為這只是重複。

There's there's no data to base anything on right.

沒有任何數據可以作為依據吧。

Um it's it's an open question at present.

嗯，這是一個開放的問題，目前。

There's a strong scientific consensus that our universe began with what we call the Big Bang 13.8 billion years ago.

有一個強烈的科學共識，即我們的宇宙始於我們稱之為138億年前的大爆炸。

A singularity, a point of infinite density expanded, sending forth matter and energy.

一個奇點，一個無限密度的點擴大了，發出了物質和能量。

So the Big Bang is the observed truth, but there are details that haven't been quite worked out.

是以，大爆炸是被觀察到的真相，但有一些細節還沒有完全被解決。

There are a lot of things that may have happened.

有很多事情可能已經發生。

It's just one explanation, but that just raises more questions.

這只是一種解釋，但這只是提出了更多的問題。

Where did all that matter and energy come from since spacetime was created with the Big Bang?

既然時空是隨著大爆炸而產生的，那麼所有的物質和能量是從哪裡來的？

Maybe it doesn't make sense to ask what came before the singularity.

也許問奇點之前有什麼是沒有意義的。

To ask what's before the Big Bang?

要問大爆炸之前有什麼？

What's before there is time is really a meaningless question And likewise, to ask where the Big Bang occurred is meaningless because there was no space.

在有時間之前是什麼真的是一個毫無意義的問題。同樣，問大爆炸在哪裡發生也毫無意義，因為沒有空間。

But we can ask why is there something rather than nothing.

但我們可以問為什麼會有東西而不是沒有東西。

One possible answer is that the universe is cyclical moving between Big bangs and big crunches, the stars will collide, the planets will collide planets will get swallowed by stars.

一個可能的答案是，宇宙在大爆炸和大壓縮之間循環往復，恆星會碰撞，行星會碰撞，行星會被恆星吞噬。

Even that though, doesn't really answer all of our questions.

即使這樣，也沒有真正回答我們所有的問題。

Number one life, when we ask why there's something rather than nothing.

第一生命，當我們問為什麼有東西而不是沒有東西。

It can also be a way of asking why are we here?

它也可以是一種問我們為什麼在這裡的方式？

How are we here?

我們怎麼會在這裡？

Why were the initial conditions of the universe such that life could arise?

為什麼宇宙的初始條件是這樣的，可以產生生命？

How did Adams come together and start thinking about themselves?

亞當斯是如何走到一起並開始思考自己的問題的？

In 1953 1 scientist shook the world when he proposed an answer.

1953年，一位科學家提出了一個答案，震動了世界。

Primordial soup, Life began on earth about four billion years ago.

原始湯，生命在地球上開始於大約40億年前。

Some scientists think that asteroids and comets brought the necessities for life to our planet.

一些科學家認為，小行星和彗星將生命的必需品帶到了我們的星球。

The latest theory is that chemicals spewing from underwater volcanic vents solidified and created towers like these.

最新的理論是，從水下火山口噴出的化學物質凝固了，形成了像這樣的塔。

And this produced the conditions needed for the first cells to form believers in panspermia hold that life originated elsewhere and was brought via the same means.

而這產生了第一個細胞形成所需的條件，泛生論的信徒認為，生命起源於其他地方，並通過同樣的方式帶來。

Another important idea, which is the one that I would subscribe to is down at the bottom of the oceans in deep sea hydrothermal vents where you've got this continuous flow.

另一個重要的想法，也是我贊同的想法，就是在海洋底部的深海熱液噴口，你有這種連續的流動。

This continuous energy flow animating everything from the very beginning.

這種連續的能量流從一開始就使一切都充滿了活力。

However, this just defers the question, how does life form So far?

然而，這只是延後了問題，生命是如何形成的到目前為止？

Scientists have been unable to create new life from scratch, although with time, who knows, there are many theories.

科學家們一直無法從頭開始創造新的生命，儘管隨著時間的推移，誰知道呢，有很多理論。

Nobody knows exactly how or where life began.

沒有人確切地知道生命是如何或在哪裡開始的。
