Perhaps their capabilities would only be limited
也許他們的能力只會
by how much power they could harness and control.
受到所掌控能源多少的限制
And that could be far more than we might first imagine.
那有可能遠遠超出我們的預料
For example, it might be possible to collect the energy from an entire star.
比如，也不無可能從一整顆恒星上收集能量
To do that, they could deploy millions of mirrors in space,
為此，他們可以在太空中安置無數面鏡子
encircling the whole sun and feeding the power to one single collection point.
環繞整座太陽，并將其能量匯集到一處
Such power might make it possible
如此驚人的能量也許能夠
to walk the very fabric of space
改變時空結構
and create a portal called a wormhole.
并形成一個蟲洞時空隧道
This portal would act like a shortcut,
這條通道會成為一條捷徑
allowing them to travel huge distances in the blink of an eye.
讓外星人能在瞬間穿越漫長的距離
Like us, they would probably have evolved from
像我們一樣，他們也許也是從
a species used to exploiting whatever it can.
開采周圍一切能源的物種進化而來
So, if aliens ever visit us, I think
如果外星人有朝一日前來拜訪我們
the outcome would be much as when
我認為結局會非常類似
Christopher Columbus first landed in America,
克里斯多弗·哥倫布初次登陸美洲
which didn't turn out very well for the native americans.
眾所周知，那對美洲原住民是一次災難
So the journey that started with the search for water
始于尋找外天外水源的外太空之旅
has led us to far off worlds which I think could exist.
我們已經進入了一個可能存在的遙遠世界
Worlds where the conditions and chemistry allow life to begin,
那些世界的環境和化學條件可以孕育生命
and then change into many different forms.
并演變出豐富多彩的形態
Even so, little green men are probably pretty rare.
即便如此，外星人依然很罕見
But in such a massive place as the cosmos,
而在如此浩瀚的宇宙中
we only have to look at ourselves for proof that
我們只要看看自己就足以證明
extremely unlikely things can and do happen all the time.
最不可能發生的事情隨時都能發生
Let's just hope that if aliens do find us,
讓我們祈禱，如若外星人找到我們
they'll come in peace.
他們是為和平共處而來
