So Cooper falls into the black hole, ends up in a tesseract and TARS gets the quantum data. Coop deduces that it was made by humans far in the future that have been able to transcend space and time.

Ok, we know that humanity is on the brink of failure, and the data on how to get the facility into space is in the data that's given to what's-her-face by Coop through the bookcase (which I still think is dumb). Now how would beings in the far future exist if we assume that humanity died because they never got the quantum data required?

Are we to believe that the chicken came before the egg?

I would think that from every decision we make, there is another universe that is spawned where the choice we make is the opposite of the one we made in reality. Aka alternate realities. If the movie is explained in that way. Maybe there was another way that Coop found NORAD, like if the prof straight out approached him and he said yes. Then from that reality, he went into bookcase scene to make it happen.

In the end it was a scifi movie, you could make up just about anything to make it plausible or justified. haha

WHY ARE YOU WHISPERING THEY CAN'T HEAR YOU

he went into the 5th dimension where every single possibility of every single time in the 3d exists... the 5th dimension is something just like... it IS space time fabric, therefore all of it exists already, and you can modify it as you wish... paradox is normal. catch 22 is normal. because you cannot think of time as linear like the way we do in 3 dimensions. it's like a strip of tape, and he edits the end which loops back to the beginning... something like that.

basically, you can't think of time linearly like the way we do in upper dimensions, all of it exists... like if we rolled out a reel of a movie. the movie doesn't have to play out for the things to happen, they all exist already

So apparently, Cooper and Brand are doomed to die alone:

Even with a gravatic drive, he'd never make it!

lol i always thought the big future base near saturn was a staging ground, a forward base for going back and forth through the wormhole... wtf if there's no wormhole how can he even get to her?

anyway... it doesnt matter what the "original" timeline is... all timelines are equal. you just live the one u are in or the one you get to. the ones that turn to disaster already exist... there must be an infinite amount of timelines where they all die, but it doesnt matter, cuz he jumps into the one where they don't die so... yeah lol, basically, fuck the other timelines, they don't matter.

Yeah, I thought the same thing as well. Especially when they showed all the new Rangers in the launch bay. "Cool! Humanity's doing something and venturing out in the universe!". Nope. Not the case... probably exploring pluto or some shit. I really wanted to see the ship in action but the film ended. Saved money for sure... but it was really the only thing that really captured my attention. :(
