1. The distance between Earth and the Moon is enough to fit all the planets in the solar system!
1.地球到月球的距離足以容下太陽系所有星球！

And then too, you will still have space left!
然后還有剩余空間！

2. Saturn can float on water!
2.土星能浮在水上！

If one can find a big enough body of water and put Saturn on it, it would actually float! This is because Saturn is mostly gaseous and its density would be less than water.( If calculated it would turn out to be something around 700kg/m^3; Density of water is 1000kg/m^3).
如果能找到足夠大的水池并把土星放水上，它真能浮起來！這是因為土星主要由氣體構(gòu)成，密度比水?。ㄓ嬎憬Y(jié)果是土星密度約為700kg/m^3，水的密度是1000kg/m^3）。

3. There is a reservoir of water in space!(sort of)
3.太空里有一個水庫！

Astrophysicists have found a cloud that harbors 140 trillion times the water that is found on Earth. Simply put, it can supply 140 trillion planets as full of water as Earth is. But it is still unclear whether the water is D2O(Heavy Water/Deuterium oxide) or not.
天體物理學家發(fā)現(xiàn)了一個云團，儲水量是地球總水量的140萬億倍，簡單點說能把140萬億個地球這樣的星球注滿水。但仍不清楚水的成分是否為D2O（重水/氧化氘）。

4. There are more stars in the observable universe than there are grains of sands on all the beaches of the earth combined!
4.可觀測的宇宙范圍內(nèi)星星的數(shù)量要比地球上所有沙灘加起來的沙粒要多！

There are about 5-10 times more Stars in the observable universe. There are very roughly around 7.5 x 10^18 grains of sand. That's actually a very big number.
可觀測的宇宙范圍內(nèi)星星的數(shù)量要多出5-10倍，沙粒總數(shù)約為7.5 x 10^18，數(shù)量真的很龐大。

5. The entire human population is not big enough to completely fill the Grand Canyon!
5.總?cè)丝谶€不夠填滿科羅拉多大峽谷的！

6. Scientists have been successfully able to reach temperatures as low as a billionth of a degree higher than the absolute zero
6.科學家已經(jīng)成功達到低至比絕對零度高十億分之一度的溫度。

7. Scientist have also been successful to slow down light to 17m/s and then stop it completely for over a minute
7.科學家也成功把光速降低到17m/s，并徹底靜止超過一分鐘。

YES! They were able to stop it for a whole minute! In that time, light could have made 30 round trips to the moon!
對！他們成功地將光靜止整整一分鐘！這一分鐘內(nèi)光都能到月球往返30圈了！

8. If you scale an apple to the size of the Earth, an atom would be the size of a normal apple
8.如果你把一個蘋果放大到地球那么大，那一個原子就像普通蘋果那么大。

9. Weight of a Hurricane
9.颶風的重量

You see that white, fluffy cloud in the sky? How much do you think it weighs? I mean, its floating right? It can’t possibly weigh much, right?
你看到天上白色松軟的云了嗎？你覺得它有多重？我的意思是它在飄著吧？不可能太重，對吧？

Well, the average white cloud actually weighs around a 100 metric tons!
嗯，其實白云平均重量約100噸！

So how do they stay afloat? They stay afloat due to the rising warm currents of air which don’t let the water from the clouds fall!
那它們怎么能一直飄著呢?它們能一直飄著要歸功于上升的暖氣流不讓云中的水掉下來！

Okay, so, If a white cloud weighs this much, how much would a black cloud weigh(The average storm cloud)?
好了，那么如果白云這么重，那烏云（普通的風暴云）會有多重？

A whopping 50,000 metric tons!! To get a perspective how heavy that is, it weighs the same as 280 blue whales!
重量驚人達50,000噸??！形象一點描述的話，這個重量相當于280頭藍鯨。

Now, to the main topic, how much would a hurricane weigh?
言歸正傳，颶風有多重？

If you consider the typical hurricane that strikes the US, it weighs a staggering 50 Million Metric tons!!
以襲擊美國的典型颶風為例，重量竟達5千萬噸??！
