All language subtitles for The Ending Of Arrival Explained.en

Denis Villeneuve's sci-fi drama Arrival hit
theaters in 2016 and earned rave reviews from

critics, thanks to Amy Adams' brilliant performance,
Villeneuve's excellent direction, and a mature,

focused take on the alien invasion genre.

But that doesn't mean it isn't confusing.

In fact, Arrival's focus on linguistics and
space-time theory is tough to untangle, and

only seems to get more complex the deeper
you dive into it.

But we've got you covered.

If you're ready to dig deep and don't mind
spoilers, here's everything you need to know

about Arrival's confusing ending.

The Sapir-Whorf hypothesis

If you want to understand this complex film,
first you need to wrap your head around the

linguistic theory at the center of it, which
holds that our perception of reality is either

altered or determined by the language we speak.

An example of the hypothesis in action: the
Hungarian word for "raccoon"—an animal that

doesn't exist in Central Europe outside of
television and zoos—is "mosómedve," which

literally translates to "washing bear."

The idea is that Hungarians' colorful term
for raccoons also affects their perception

of the creature itself, so that they see and
understand it differently than those of us

who just call a raccoon a raccoon… or a
trash panda.

Rewiring Louise's brain

So, the Sapir-Whorf hypothesis states that
our reality is determined by our language.

In Arrival, that argument is pushed to its
outer limits.

Dr. Louise Banks is the one who first begins
to truly learn and comprehend the Heptapod's

strange, non-linear mode of communication.

Thus, she's also the first to perceive reality,
space, and time the same way the aliens do.

The total overhaul of Louise's reality begins
shortly after she teaches the heptapods her

and Ian's names.

While dissecting some printouts of the alien
language, she has this vision of her daughter

playing with a caterpillar in a field—a
moment easily dismissed as a random memory

of the daughter she lost.

But these flashbacks intensify and appear
more frequently as she learns more of the

Heptapods' language, leading to a bombshell
moment in which what seemed like memories

are now revealed to be visions of Louise's
future:

"I don't understand, who is this child?"

Weapon opens time

Dr. Banks' job is to find out why the Heptapods
came to Earth, leading to a global international

crisis when the Heptapods say that they're
here to, quote, "give weapon."

But what Louise realizes is that the aliens
don't really mean "weapon"; they mean "tool,"

and the tool they intend to give humanity
is their language — which will come in handy

3,000 years from now, when the Heptapods face
extinction and need humanity's help.

Since people who speak Heptapod experience
time in non-linear form, they're capable of

drawing on experiences from anywhere within
their own existence to make choices and change

events.

That's how Louise is able to flash forward
18 months to the gala where she encounters

Chinese General Shang, who tells her what
she said to him to stop him from starting

a war of the worlds in the present.

And since Shang has learned to speak heptapod
himself in those intervening months, he also

perceives time non-linearly — so he knows
that what he tells Louise in his timeline

will be useful to her past self.

Confused?

Let Rust Cohle help you out.

"We see… our space-time would look flattened."

Heptapod time is like that beer can: a flat
circle.

And on a flat circle, cause-and-effect can
happen in any direction.

What Louise says to Shang leads him to speak
to her at the gala — but what Shang says

to Louise at the gala also leads her to say
what she said.

And that makes perfect sense, as long as you
accept one more hypothesis.

Everything is pre-determined

Needless to say, Louise returns from her mental
flash-forward to make the phone call that

saves the world, and everyone lives happily
— or tragically — ever after.

But what if she simply chose not to?

That's the bad news: she can't choose.

"Now you know."

In order for that future conversation at the
gala to happen — and it does — Louise

has to follow through on the phone call.

This is the other big difference between linear
and non-linear time.

In linear time, you can make choices that
alter the shape of your future; you might

be able to move in only one direction, but
every choice you make represents a fork in

the road.

In non-linear time, life is a circular track
on which you can travel either backward or

forwards, but there's no branching off.

The existence of free will is fundamentally
incompatible with a non-linear experience

of time, which is also the heart of Arrival.

Speaking heptapod gives Louise the ability
to see the future, but shatters her illusions

of ever being able to change it.
