"The science of Interstellar lies in all four domains: Newtonian, relativistic, quantum, and quantum gravity."

"Interstellar is an adventure in which humans encounter black holes, wormholes, singularities, gravitational anomalies, and higher dimensions.

So lets see where Rangers, Endurance, the Lazarus missions (Lazarus meaning come back to life after death...) can lead us...

On physics -

US "corrected" the textbook by saying Apollo plan was fake and bankrupted Soviet Union, i.e. humans never landed on the lunar (moon).

One of those useless machines they used to make was called an MRI 核磁共振. If we had any of those left, the doctors would've been able to find the cyst in my wife's brain before she died instead of afterwards. Then she'd have been the one listening to this instead of me...

Earth's atmosphere is 80% nitrogen. We dont even breathe nitrogen. Blight (枯萎病) does. And as it thrives, our air gets less and less oxygen. The last people to starve will be the first to suffocate (窒息). And your daughter's generation will be the last to survive on Earth.

There is not a planet in our solar system that could sustain life and the nearest star is over 1000 years away.

We started detecting gravitational anomalies almost 50 years ago. Mostly small distortions to our instruments in the upper atmosphere.

A wormhole is not a naturally occurring phenomenon.

That wormhole lets us travel to other stars. It came along right as we needed it.

So they say you want to go from here to there. But it's too far, right?

Mm-hm.

So a wormhole bends space like this, so you can take a shortcut through a higher dimension. To show that, they've turned three-dimensional space into two dimensions which turns a wormhole into two dimensions, a circle. What's a circle in three dimensions?

A sphere.

Time is relative. It can stretch and it can squeeze, but it can't run backwards. It just can't. The only thing that can move across dimensions, like time, is gravity.

We've been trying to solve the equation...without changing the underlying assumption about time. And that means each iteration is an attempt to prove its own proof. It's recursive. It's nonsensical.

The laws of nature prohibit a naked singularity.

If a black hole is an oyster, then the singularity is the pearl inside. The gravity is so strong. It's always hidden in darkness...behind the horizon. That's why we call it a black hole.

Okay, but if we see beyond the horizon...

We can't, Coop. There are some things that aren't meant to be known.

Gargantua is an older spinning black hole. It's what we call a gentle singularity.

Gentle?

They're hardly gentle, but the tidal gravity is so quick that something crossing the horizon fast might survive. A probe, say.

What happens after it crosses?

After the horizon is a complete mystery. So, what's to say there isn't some way that the probe can glimpse the singularity and relay the quantum data? If he's equipped to transmit every form of energy that can pulse.

What are the five dimensions? Space (3D), time (4th), gravity (5?)

A civilization that's evolved past the four dimensions we know.

On family/parents -

Well, I guess that answers the old "if I asked you to drive off a cliff" scenario.

It takes two numbers to measure your ass but only one to measure my son's future?

Now we're just here to be memories for our kids.

Once you are a parent, you are the ghost of your children's future.

Murph was smart enough to sense that her father didnt know when he would come back... (for me I only feel this is so sweet/cozy... see the difference lol

When I'm up there in hypersleep, or travelling near the speed of light, or near a black hole, time is gonna to change for me. It's gonna run more slowly. When we get back, we're gonna compare.

Time will run differently for us?

Yeah!

By the time I get back, we might even be the same age, you and me.

When you become a parent, one thing becomes really clear. And that is that you want to make sure your children feel safe. And that rules out telling a 10-year-old girl that the world is ending.

No parent should have watched their own child die.

On humanity -

Why did you and Mom name me aftr something that is bad?

We didn't.

Murphy's Law?

Murphy's Law doesnt mean that something bad will happen. What it means is whatever can happen will happen.

We used to look up to the sky and wonder at our place in the stars. Now we just look down and worry about our place in the dirt.

Don't trust the right thing done for the wrong reason. The why of the thing, that's the foundation.

Absolute honesty isnt always the most diplomatic, nor the safest form of communication with emotional beings.

It is not Morse (dots and dashes). It is binary. Thick is one, thin is zero. Coordinates.

Poem by Dylan Thomas (UK) -

Do not go gentle into that good night

Old age should burn and rave at close of day

Rage, rage against the dying of the light

Though wise men at their end know dark is right

Because their words had forked

No lightening they

Do not go gentle into that good night

It only has to work once, Murph.

We must think not as individuals, but as species.

Murphy's Law. Whatever can happen will happen.

Accident is the first building block of evolution. But when you are orbiting a black hole not enough can happen. It sucks in asteroids and comets, other events which would otherwise reach you.

When I say that love isnt something we invented. It's observable, powerful. It has to mean something.

Love has meaning, yes. Social utility, social bonding, child rearing.

We love people who have died. Where is the social utility in that?

None.

Maybe it means something more, something we can't yet understand. Maybe it's some evidence, some artifact or a higher dimension that we can't consciously perceive. I'm drawn across the universe to someone I haven't seen in a decade, who I know is probably dead. Love is the one thing we're capable of perceiving that transcends dimensions of time and space. Maybe we should trust that, even if we can't understand it yet.

...how hard it would be to get people to work together to save the species instead of themselves or their children.

Evolution has yet to transcend that simple barrier. We can care deeply, selflessly about those we know, but that empathy rarely extends beyond our line of sight.

A machine doesnt improvise well, because you can't program a fear of death. Our survival instinct is our single greatest source of inspiration.

Newton's third law.

The only way humans have ever figured out of getting somewhere is to leave something behind.

It's just like Brand said. My connection with Murph, it is quantifiable. It's the key!

What are we here to do?

Find how to tell her.

The watch.

We code the data into the movement of the second hand. TARS, translate the data into Morse and feed it to me.

I dont care much for this pretending we are back where we started. I want to know where we are, where we are going.
