Interstellar #2 - What happened with "Mann"

First of the two major points that stood out for me in the movie.

Dr. Mann has faked the data he found on the new icy planet and lured endurance and its scientists to land there. When he learns that cooper would be leaving the planet on his shuttle to get back to earth he takes him to a lonely spot and tries to kill him, while talking about how humans have not "yet" evolved enough to put the importance of surviving as a species above saving loved ones (which, in this context, borders on selfish). This emphasizes the fact that humans are the youngest species on the universe (meaning, if there were other species on the universe, aliens, they, as a species, would be more evolved as they've been alive for a longer period than humans). So, the "beings" mentioned every now and then can either be taken for God and Angels or as an alien race which wants to see humans grow and evolve by helping them survive.

Mann portrays the raw human nature which portrays man as being rash and selfish (when he talks about success of the mission and ultimately his glory on achieving it) but still wants to leave his cohorts behind and get out of the icy planet. while cooper is struggling to breathe through the ammonia in the atmosphere, Mann experiences an inner conflict which being human, wants to save his new friend and being a scientist wants not to jeopardize the mission. I imagine scientists going through this conflict every now and then, growing up believing something only to learn and realize that their belief system "could be" wrong. the key word here is "could be" because the biggest, life altering theories one can learn are just that, theories and not hard facts, not yet.

Sso why is the planet so icy. If u want it to be un-inhabitable u could've made it rocky with no water, an atmosphere rich with toxic gases, surface that can explode anytime, I don't know a hundred possible scenarios? and you choose ice. I believe ice shows the cold, unforgiving and non-compassionate nature of humans when it comes to putting their self before others. There's another possible explanation. Americans in general don't like the cold, they prefer warm, sunny days over the cold ones. Is that why an uninhabitable planet came to be an icy surface with frozen clouds and a final settlement camp of humans looks warm and cozy?

Interstellar #1

From the limited knowledge I gained in the past couple years I have been able to understand Interstellar and I would like to impart the knowledge to everyone who's eager to understand the movie. The explanation is in 4 parts: First we learn about the big terms and their meanings, Then we talk about the two major moments in the movie that confused everybody and finally the questions that arise once you've understood what you've seen and an attempt to try and answer them yourself. So in this first post lets see about those big terms.

- Wormholes are a purely theoretical concept which exist only as mathematical equations and in science fiction. They're a shortcut through space-time which enables us to cover greater distances in space. Its highly improbable that a wormhole exists in space that would allow such a travel.

- Black holes are real and they do exist in the observable universe.

*Contrary to popular belief they're not holes in the middle of the universe

*They're not stars that have burst/ exploded and left a gap in the middle of the universe

*A black hole is a star that has expanded beyond a certain critical mass, which resulted in its gravity increasing exponentially and due to such gravitational pull its impossible for anything (including light, the fastest observed wave/particle in the universe) to escape from the surface of it. Since there's no light being emitted from it, it has to appear like a black gap in the middle of the universe (which has been visually imagined in this movie)

- Event Horizon is usually recognized as the space surrounding the black hole. where the pull of gravity is infinity.

- Singularity is a tiny point in space where density of matter is infinity and time didn't exist. It is believe that the universe came to be, from such a singularity.

-Theory of relativity : Time is relative, the reference of time differs from observer to observer based on the point from where they're observing it. Time is faster for astronauts in orbit and comparatively slower for observers on earth. To understand this concept let's consider an illustration from "The Grand Design" which goes like this.

(this example is not to be confused over the train example for inertia) : person A is bouncing a ball while travelling on an airplane, when the ball hits the ground and bounces back, for an observer inside the plane (A) the ball has not traveled any distance over time. It has just gone down and bounced back to his hand. But for an observer on the ground (person B) watching the ball bounce inside the plane, when the ball went down and bounced back up it has travelled from position x --> y over time. So the flow of time appears different for every observer based on the point of observation.

- And finally, gravity stretches time through space. If you're on an object in space that exerts high gravity like a black hole, for an observer on the black hole time runs at the same speed as before entering it, but for an observer from outside the black hole, time stretches and expands and hence appears to have moved faster (and hence have run longer) with reference to the person on the black hole.
