情態副詞

What will happen, if all 7,000,000,000 people on earth simultaneously jump up and down?

如果地球上 70 億人同時向上跳躍會發生甚麼事呢？

If everyone jumps at home, nothing significant will happen.

如果大家在家跳起來，不會有甚麼明顯改變

Even if we jump up and down the whole day long.

But, if we were to collect all people of the earth in one place, we could very quickly solve a rather important problem: Overpopulation.

但是，如果我們能把地球上所有人都聚集在一塊地上，我們就能迅速解決一個相當嚴重的問題：人口過剩

Probably you have heard something about us humans multiplying our numbers much too quickly.

也許你曾聽過關於地球人口倍數增加過快的說法

If nothing is done, soon there won't be any food left.

如果不解決，我們很快就會面臨食物短缺

One way of looking at it, 7,000,000,000 is not so much,

其中一個觀點是，70 億人口其實也不多，

so all the people on earth could easily fit into a territory equal to the size of Moscow or Los Angeles, for example.

所以地球上所有人都能輕鬆容納進如莫斯科和洛杉磯一般大小的地區

OK, let's say we all gather on a hypothetical huge platform one meter of the ground and are ready to make this collective jump.

好的，假設我們都聚集在一塊超大土地並同時向上跳 1 公尺

This jump will create a truly significant amount of energy, part of which will return back to each person through their shoes.

這個跳躍會製造出超大能量，且其中一部分能量會從我們鞋底灌回

And, some of which will dissipate into the environment with very interesting consequences.

並且，一些能量會散至環境，造成有趣的後果

First, you will hear a very loud sound of about 200 decibels, similar to the sound of applause, only much much louder.

首先，你會聽到大約 200 分貝的巨大聲響，就像鼓掌聲一樣，只是更大聲得多

A jet engine emits a sound volume of 140 decibels.

160 is the level of a shock wave from a supersonic aircraft.

160 分貝相當於超音速飛行機的震波

The pain threshold of a human being is already passed at a level of a mere 130 decibels.

音量早已超過人類能承受的 130 分貝的門檻

150 shock and severe injuries and 200 decibels - at best such a sound will simply blow your eardrums.

150 分貝時造成腦震盪，和嚴重傷害，而到 200 分貝時，這樣的聲量所帶來的最小傷害是震破耳膜

That's at best, but basically, everyone will just die.

這只是最小的傷害，但基本上在這種情況，大家都會死光

You are incredibly lucky, but not for very long.

It turns out that our jump strongly impacted the planet and in response to this degradation the earth will send a 30 meter high tsunami rolling back onto shore.

我們的跳躍大力衝擊地球，地球製造 30 公尺高海嘯侵襲海岸以回應環境劣化

Along with a couple of earthquakes of around 4 to 8 on the Richter scale.

伴隨幾個芮氏規模 4 到 8 級的地震

As a consequence, bridges, railways, powerlines and some buildings will be destroyed.

最後，橋梁、鐵路、電纜和一些建築將會毀壞

But, I must confess to you nothing will happen.

但是，我得向大家承認其實甚麼事也不會發生

If we were able to bring together 7 billion people and make them jump at the same time, everything would be like this:

如果我們能將 70 億人聚集在一起並同時跳躍，畫面看起來會像這樣
