There are still lots of things about space

情態助動詞 B1

Or are aliens living somewhere else in the Milky Way?

But there is one thing I believe about space:

It's also trying to kill you and everybody else.

Space doesn't naturally have what we need to survive

no ozone to protect us from those nasty UV rays, either.

沒有臭氧層可阻擋惱人的紫外線

What we need to understand is that objects in space

can cause people to think their days are numbered,

So, what are the odds that one of these objects

Well, we can take what we know about the universe

Scientists think asteroids might have killed off

Sounds like something we should worry about, right?

Well, astronomers can now watch asteroids in space

天文學家已能觀察太空中的小行星

and see them coming using complex computer models

that asteroid Apophis would strike Earth in 2036

小行星阿波菲斯 (Apophis) 2036 年撞擊地球的機率

astronomers now say the chances are extremely low.

天文學家現在認為，可能性極低

好萊塢電影喜歡在太陽上作文章

by showing Earth destroyed by solar flares

Astronomers predict our sun contains enough gas

天文學家預測太陽有足夠的燃料

to make energy for another 3 to 5 billion years.

Sometimes the sun does shoot flares at Earth,

有時太陽的確會朝地球發出閃焰

but the magnetic fields surrounding our planet

Gigantic solar flares can mess with our satellites

巨型的太陽閃焰會干擾人造衛星

but the chances of it killing you are pretty slim.

Okay, what about that supermassive black hole

That's one big object that can't bother us.

Our solar system is on the edge of the Milky Way

我們的太陽系，在銀河系的邊緣

while the nearest supermassive black hole

That means we aren't on that black hole's menu.

So, you still think space objects are trying to kill you

just to make sure nothing is headed my way.
