第二類條件句型

What would happen to the Earth if the Sun suddenly switched off is probably the single most popular question submitted to What If.

「如果太陽突然熄滅，地球會怎樣？」這可能是 What If 這個頻道上最受歡迎的問題。

程度副詞

A search for what if the Sun went out turns up lots of excellent articles thoroughly analyzing the situation.

搜索 "如果太陽熄滅了怎麼辦 "時，會出現很多對這種情況進行深入分析的優秀文章。

However, there are a few aspects of this scenario that I thought other answers were missing, so I've decided to add my two cents.

不過，我認為其他答案在這個場景中缺少了幾個方面，所以我決定補充我的兩點意見。

We won't worry about exactly how it happens. We'll just assume that the Sun for some reason becomes a cold inert sphere.

我們不關心它究竟是如何發生的，我們只假設太陽由於某種原因變成了一個冷的惰性球體。

What would the consequences be for us here on Earth?

Without the Sun, ground-based observatories would be able to operate around the clock.

如果沒有太陽，地面天文臺就可以晝夜不停地運作。

The cooler air would create less atmospheric noise, which would reduce the load on adaptive optic systems and allow for sharper images.

較冷的空氣會產生較少的大氣噪音，從而減輕自適應光學系統的負荷，使影像更加清晰。

When a communication satellite passes in front of the Sun, the Sun can drown out the satellite's radio signal causing an interruption in service.

當通信衛星從太陽前方經過時，太陽會淹沒衛星的無線電信號，導致服務中斷。

Deactivating the Sun would solve this problem.

停用 "太陽 "可以解決這個問題。

Time zones make trade more expensive, it's hard to do business with someone if their office hours don't overlap with yours.

時差使貿易成本更高，如果某人的辦公時間與你的不一致，就很難與他做生意。

If the Sun went out, it would eliminate the need for time zones, allowing us to switch to coordinated universal time and give a boost to the global economy.

如果太陽熄滅了，時區就不再需要，我們就可以切換到協調的世界時，從而促進全球經濟的發展。

In 1859, a massive solar flare and geomagnetic storm hit the Earth.

1859 年，巨大的太陽耀斑和地磁暴襲擊了地球。

A basic principle of physics is that changing magnetic fields induce currents in wires.

物理學的一個基本原理是，變化的磁場會在導線中產生電流。

Unfortunately for us, by 1859 we had wrapped the Earth in Telegraph wires.

不幸的是，到 1859 年，我們已經用電報線將地球包裹起來。

The storm caused powerful currents in those wires, knocking out communications and in some cases causing Telegraph equipment to catch fire.

暴風雨在這些電線中產生了強大的電流，造成通信中斷，有時還導致電報設備起火。

Since 1859, we've wrapped the Earth in a lot more wires.

自 1859 年以來，我們用更多的電線將地球包裹起來。

If the 1859 solar flare and storm hit us today, it's estimated that the economic damage to the US alone would be several trillion dollars.

如果 1859 年的太陽耀斑和風暴在今天襲擊我們，據估計，僅對美國造成的經濟損失就將達到數萬億美元。

More than every hurricane which has ever hit the US combined.

比曾經襲擊過美國的所有颶風的總和還要多。

If the Sun went out, this threat would be eliminated.

如果太陽熄滅了，這種威脅也就消除了。

We'd also be safe from hurricanes since the ocean would be frozen.

我們也不會受到颶風的侵襲。因為海洋會結冰。

The Department of Transportation estimates that it will cost $20 billion per year over the next 20 years to repair and maintain all US bridges.

據美國交通部估計，在未來 20 年內，每年將花費 200 億美元來維修和保養美國的所有橋樑。

Many US bridges are over water, without the Sun, we could save money by simply driving on a strip of asphalt laid across the ice.

美國的許多橋樑都架設在水面上，如果沒有太陽，我們只需在冰面上鋪設一條瀝青路面，就能節省開支。

According to health experts, babies younger than six months should be kept out of direct sunlight.

健康專家指出，6 個月以下的嬰兒應避免陽光直射。

Without sunlight, our children would be safer.

沒有陽光，我們的孩子會更安全。

Many people sneeze when exposed to bright sunlight.

The reasons for this reflex are unknown, but in some situations, it's speculated that it may pose a danger to pilots during flight.

這種反射的原因尚不清楚，但據推測，在某些情況下，它可能會在飛行過程中對飛行員造成危險。

If the Sun went dark, we could mitigate this potential aviation hazard.

如果太陽變黑，我們就可以減少這種潛在的航空危險。

Without sunlight, there would be no pointing Robertson drag, which means we would finally be able to place dust into a stable orbit around the Sun without the orbits decaying.

沒有陽光，就不會有指向羅伯遜的阻力，這意味著我們終於能夠將塵埃送入環繞太陽的穩定軌道，而不會發生軌道衰減。

I'm not sure whether anyone wants to do that, but you never know.

我不確定是否有人願意這麼做，但世事難料。

While parsnip is a surprisingly nasty plant, its leaves contain chemicals called furocoumarins, which can be absorbed by human skin without causing symptoms at first.

雖然歐洲防風草是一種令人吃驚的討厭植物，但它的葉子中含有一種叫做呋喃香豆素的化學物質，這種物質可以被人體皮膚吸收，但一開始不會引起症狀。

However, when the skin is then exposed to sunlight, even days or weeks later, the furocoumarins cause a nasty chemical burn.

然而，當皮膚暴露在陽光下時，甚至在幾天或幾周後，呋喃香豆素就會造成令人討厭的化學灼傷。

A darkened Sun would liberate us from the parsnip threat.

黑暗的太陽會把我們從歐洲防風草的威脅中解放出來。

In conclusion, if the Sun went out, we would see a variety of benefits across many areas of our lives.

總之，如果太陽熄滅，我們會在生活的許多領域看到各種好處。

Are there any downsides to this scenario?
