we were talking about the, um...
The Fermi paradox？
Right, the Fermi paradox.
The, uh contradiction of having a high probability
of life existing elsewhere in the universe
while having no actual evidence to prove it.
The Drake equation.
It gives us every reason to believe
that life should be common in our galaxy
So why haven't we found anything?
Over 100 billion stars in the Milky Way,
the vast majority of which host planets,
many of those planets capable of supporting life
and still we have found nothing.
No sign of anyone or anything else.
And believe me, we're looking.
Night after night, after night, we're staring up at the sky,
burying ourselves in mountains of data.
All because we know one day, we will crack this thing.
And if we don't,
you will right?
Yeah, go ahead.
Didn't NASA predict
we'll find evidence life exists
beyond Earth within the next decade?
After you've been in this field a while
you'll learn to take predictions with a grain of salt.
But the game is changing though.
The TESS and James Webb telescopes launch soon,
we'll stand a much better shot at finding something.
It just seems like you...
拜托 别停啊 越来越有趣了
Please. Don't stop. This is getting interesting.
If you're frustrated
that you personally haven't found anything,
then maybe it's pointless for you to keep looking.
I'm curious, is that a fact or just your opinion?
Look, I just think...
-你觉得 那是你的想法咯 -对啊
- You think. So it's your opinion. - Yeah.
If you feel this is a dead end to you that wastes your time,
might as well do other things.
What other things could be more important to humanity
than answering the question, "Are we alone?"
或者 甚至 爱
Or like, love, even?
Love? That's pretty good.
Remind me of your name.
Uh, you're seeing anyone, Kiefer?
No not really.
Okay. Why don't we do what scientists do?
Let's take a look at the data.
All right. L is the value of love.
Now, we have 250 students in this class, or...
At least, enrolled in this class.
Four out of every five of you statistically will get married.
So, that's 200 students married.
Now last year we learned that two out of five marriages
will end in divorce.
Which gives us 120.
One hundred and twenty of you who
will fall in love and stay married.
That's less than half the people in this class.
But that's just marriage.
You're absolutely right. Let's talk about the 85%
of relationships that end in break-ups.
Or the 20% of breakups that lead to depression,
or the 3% that lead to suicide.
Well, wait. Let's talk about the 56% of people
who admit to a history of infidelity in their relationship.
Those are just random statistics,
they don't actually prove anything.
I wanna ask you guys something. And be honest.
Raise your hand if you've ever been hurt by love.
Plug values into the Drake Equation,
we'll sure as hell get a number higher than zero.
You get to choose what you waste your time on, Kiefer.
Outer space is a safer bet.
Is that a fact?
Is that a fact or is that just your opinion?
It's an educated opinion.
Let's open up our books to page 237.
I was reading this article online about life hacks.
I read one that says increase productivity
and maximize your health with a
30-minute bike ride every morning.
I'm like, that's not a life hack.
That's just something you can do.
Hey, those aren't images from the galactic center.
Isaac, you can't be shifting the telescope
to fish for Earth masses.
This is your advisor's grant money, not yours.
-调回去 -我调了 淡定
-Switch it back. - I did. Relax.
It's still there. Switch it back, please.
I don't... Is that time stream data transferred yet?
It says one minute.
I don't know why you can't just wait for
the TESS to launch like everyone else.
I'm just getting a head start.
While every citizen scientist and their dog wait for that data,
I can actually be looking for a habitable planet.
Come on, you're telling me you just want to be another guy
sitting at home looking at TESS data in your underwear?
Actually, yes. That's a life-hack.
I might go commando.
Just a robe. Get a nice breeze going.
-乔勒 你好 -你好
- Hey, Joelle. Hi. - Hey.
You didn't hear what we were just talking about, did you?
Doesn't matter. Um...
This is somehwere here.
All right, now, your error calculations were great,
but you mislabelled the axes on your plots.
I didn't dock you for it.
Just something to keep in mind for the formal report. Okay?
You should be happy. You did well.
