科普你：8个会让你大跌眼镜的事实

5. You thoroughly enjoy celebrating some pretty dark holidays.
你喜欢过的节日中许多相当暗黑。

Labor Day was created as a bandaid to coverup multiple massacres of American workers. Columbus Day is named after a brutal tyrant whose history is largely a fraud. Thanksgiving is a sham celebration of Pilgrims and Native Americans coming together.
劳动节是一个为了抹饰美国劳工大屠杀的历史而设立的节日。哥伦布日是以一个残酷暴君的名字来命名的，此人在历史上完全是一个骗子。感恩节是初到北美洲的朝圣者们兴起的，为了庆祝朝圣者们和美洲原住民欢聚一堂的鸿门宴。

6. A whole ecosystem lives in your belly button.
你的肚脐眼里有一整个生态系统。

Scientists found 2,368 different species of bacteria living in belly buttons after swabbing the navels of just 60 people. In that study, 1,458 might have been entirely new to the scientific record.
科学家们在60名志愿者的肚脐上提取样品，发现我们的肚脐眼里可以找到2386种不同的细菌。研究发现的细菌种类中，有1458种是科学家们从未遇到过的。

7. YYou'll also never see all the beautiful colors of a rainbow.
你永远不会看到彩虹上所有美丽的颜色。

Everyday you are missing out on aspects of the universe simply because our bodies cannot process their wonders.How can we be supreme rulers of the world and have full domain over all other living beings when chickens can see more colors than we can?
每天我们都在错过宇宙中的某些奇景，因为我们的身体无法处理这些景观。既然鸡都能比我们看到更多的颜色，我们又怎能自诩为世界的掌控者，万物的灵长呢？

We need to rethink our place. Also rainbows are actually made up of more than 1 million colors, many of which we can't see either. We are missing out!
我们需要重新思考自己在宇宙中的位置。不仅如此，实际上彩虹中有超过一百万种颜色，而这些颜色中也有很多我们看不见。我们错过的太多了！

8. We haven't figured out the secret to immortality, but this jellyfish has.
我们还没有揭开长生不死之谜，而这种水母却做到了。

The Turritopsis nutricula can live forever by reverting back to its early stage of life after becoming sexually mature. Although immortality may not be a real possibility for humans just yet, it is good to know that the basic idea isn't just science fiction.
灯塔水母能够在性成熟之后返回到生命的早期阶段，因而能够长生不死。也许长生不死对人类来说还是一种不具有现实可能性的事情，但是现在我们知道这种想法并非只存在于科幻小说里，这已经很好了。
