可能是因为他们不理解物理
It's perhaps they
don't understand physics
不了解恒星演化的定律
and the laws of stellar evolution.
我们活在恒星时代
We live in an age of stars,
但这时代将会终结
but it will come to an end.
宇宙间的氢有限
There's only so much
hydrogen in the universe.
几万亿年后就会耗尽
Trillions of years from
now, it will all be used up.
当氢耗尽, 就不会再有新恒星
And when there's no hydrogen
left, there will be no new stars.
我们活在宇宙历史上一个很短时期
We live in a very brief period
in the history of the universe,
一个仍有恒星照耀天际的时期
when we still have stars
illuminating the sky,
恒星创造生命, 但它并不恒久
stars creating life as we know it,
but it's not gonna last forever.
恒星早晚都会开始逐渐消逝
Sooner or later, the stars
will begin to blink out
首先, 巨型恒星将会烧尽
First, the massive stars will burn out.
然后是中等恒星, 例如我们的太阳
Then, mid-sized stars like our sin,
只留下最小的
leaving only the smallest
几万亿年后, 它们亦将消逝
Trillions of years later,
they too, will fade away.
慢慢地, 无可阻挡地
Slowly, inexorably,
宇宙将变得较寒冷黑暗
the universe will get colder and darker
直到最后一颗恒星烧尽
until the last star burns out
到时宇宙便再次变得黑漆漆
and the universe
becomes dark once again.
届时, 恒星时代将会结束
The age of stars will be over.
老实说, 宇宙的未来看似黯淡
Honestly, the future of the
universe looks kind of grim,
但你能往好的方面去想
but you can take something
positive out of that
这是活着的最佳时刻
This is the best time to be alive.
这是生命能繁衍, 恒星能形成之时
This is the time where life
can flourish, stars can form.
我们正处于宇宙的黄金时代
We are in the golden age
of the universe right now.
可以说, 这是宇宙的生命勃发季节
We live in a season for life
in the universe, if you will,
能维持几十亿年
that lasts for a few billion years.
因此, 我很珍惜欣赏万物的现况
And that makes me, at least,
appreciate the way things are right now,
因为以前不是这样的
because they weren't always that way
亦不会永远是这样的
and they won't always be.
我们活在恒星发亮照耀夜空的时期
We live in the stage where stars
glow and illuminate the night sky,
恒星创造生命的时期
when stars create life as we know it
我们活在宇宙最棒的阶段
We live in the best of
all stages of the universe.
暂时而言, 恒星将继续塑造宇宙
For now, stars will continue
to shape our universe.
带来建立新世界的构块
Generating the building
blocks of new worlds,
创造新恒星, 并以光明填满黑暗
creating new stars, and
filling the darkness with light.
