天体物理学家发现了一个云团,储水量是地球总水量的140万亿倍,简单点说能把140万亿个地球这样的星球注满水。但仍不清楚水的成分是否为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.
可观测的宇宙范围内星星的数量要多出5-10倍,沙粒总数约为7.5 x 10^18,数量真的很庞大。
5. The entire human population is not big enough to completely fill the Grand Canyon!

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!
