Finally saw this last night.
Good movie. Great effects.
But I have a few questions.
1: Where is all this "science" I've been hearing is supposed to be in this film?
a: Wormholes are theoretical. They may as well be fiction.
b: A massive planet orbiting a black hole doesn't get sucked into the black hole, but a tiny spaceship orbiting the planet will?
c: Cooper crosses the event horizon of a black hole and isn't atomized?
d: ...and then is spit back out into his own solar system?? (I realize this was necessary to tell a nifty story, but it's pretty far-fetched)
2: Why is it so darned important to save the human race? Sure, I would go to great lengths to protect the people I love, but the human race as a whole?
Why? What good are we? All we seem to be interested in is making our fellows suffer. When we're not dreaming up excuses to slaughter each other wholesale, we're inventing governments and economics and ridiculous ideologies and religions to oppress ourselves and others.
What do we contribute to the universe? All we do is consume resources and create garbage. So we find a new world to exploit and cripple... Will we live together in peace? Can we ever possibly live together in peace? History says "NO". What possible motivations could a sane individual have for wanting to perpetuate human suffering?
Coopers surival was because of intervention by the "bulk beings" that is the future evolved to a fifth dimensional existance humans that clearly were capable of creating a wormhole, they were also capable of creating the tesserarct for him to "land" safely in after ejecting.
There is a TON of science in this film. In fact an entire book has been written about it.

Things can orbit a black hole, that isn't an issue.
Of course dramatic license was taken, and where science said ??? or maybe, Nolan chose to take dramatic license.
As for survival of humanity. Your judging based upon the study of exactly one intelligenct known species, us.
We've no one else to compare to. Our behavior could be quite normal for our point in development.
I know it's not popular to realize this but.... the massive vast majority of humanity never kills another human being and loves their family
and would do most anything for those they love. That doesn't mean wars don't happen from time to time and could be again.. a normal
developmental stage, even a necessary step to advance.
Earth has seen massive great turmoil in it's billions of years. Huge extinction events, massive global climate changes that froze over the entire planet for eons.
Humanity will never come close to causing anything close to that. We are not as impactful as you think, we are not trashing this world.
Part of Nolan's idea for this film was... we can't live in the nest forever. Nests get nasty if you stay too long and you would not surive anyways.
Cooper even says "this planet is a treasure, but it's been telling us to leave for a while now."
It was time for us to go.
Why Space, Why Explore?
Astronaut Story Musgrave, a remarkable man........
"We have no choice, Sir. It is the Nature of Humanity, it is the Nature of Life
The Globe was created and Life Evolved, and you look at every single cubic millimeter on this Earth, You can go 30,000 feet down below the Earth surface, You can go 40,000 feet up in the air and Life is There. When you look at the globe down there, you see Teeming Life Everywhere
It is the Power of Life, And maybe I am not just a Human up here, you know. Now Life is Leaping off the Planet. It is heading to other parts of the Solar System, other parts of the Universe
There are those kinds of Pressures. It isn't simply politics, it is not simply technology, it is really not just the essence of humanity, but it is sort of also, you could look at it as maybe the Essence of Life. I think Teilhard de Chardin, in Phenomenon of Man, I believe he put that incredibly well. So those kind of Forces are at Work. It is the nature of humans to be exploratory and to Push On
Yes, it costs resources and it does cost a lot, and there is a risk, there is a penalty, there is a down side, but Exploration and Pioneering, I think those are the critical things, it is the Essence of what Human Beings are, and that is to try to understand their Universe and to try to participate in the entire Universe and not just their little Neighborhood" -Story Musgrave.
We sentient beings, evolved from the materials created in dying stars,
evolved to the point that we are now looking back into the universe, taken a few steps beyond our world,
and trying to understand the nature of the cosmos.
That is very stunning realization.... that we are the cosmo's self created conciousness to ponder itself.
And to participate, one need only look up into the night sky and recognize the minute by minute
miracles of life on this world.
Life is this powerful natural force, it has transformed this very world dramatically, we're part of that.
That's how I think of it all. Musgrave is right to point out there are natural forces at work often beyond
our immediate thinking.
, but it makes me feel almost like if he was in his own brain, so it could be it. Would that mean everybody dies?
