What are some mind-blowing facts that sound like 'BS', but are actually true?

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

And then too, you will still have space left!

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).

3. There is a reservoir of water in space!(sort of)
3.太空里有一个水库！

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.

4. There are more stars in the observable universe than there are grains of sands on all the beaches of the earth combined!
4.可观测的宇宙范围内星星的数量要比地球上所有沙滩加起来的沙粒要多！

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.

5. The entire human population is not big enough to completely fill the Grand Canyon!
5.总人口还不够填满科罗拉多大峡谷的！

6. Scientists have been successfully able to reach temperatures as low as a billionth of a degree higher than the absolute zero
6.科学家已经成功达到低至比绝对零度高十亿分之一度的温度。

7. Scientist have also been successful to slow down light to 17m/s and then stop it completely for over a minute
7.科学家也成功把光速降低到17m/s，并彻底静止超过一分钟。

YES! They were able to stop it for a whole minute! In that time, light could have made 30 round trips to the moon!

8. If you scale an apple to the size of the Earth, an atom would be the size of a normal apple
8.如果你把一个苹果放大到地球那么大，那一个原子就像普通苹果那么大。

9. Weight of a Hurricane
9.飓风的重量

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?

Well, the average white cloud actually weighs around a 100 metric tons!

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!

Okay, so, If a white cloud weighs this much, how much would a black cloud weigh(The average storm cloud)?

A whopping 50,000 metric tons!! To get a perspective how heavy that is, it weighs the same as 280 blue whales!

Now, to the main topic, how much would a hurricane weigh?

If you consider the typical hurricane that strikes the US, it weighs a staggering 50 Million Metric tons!!
