1. Movie claims that the wormhole is created by a future version of human beings who survived to evolve into five dimensional beings. Movie also claims that humanity would go extinct within a single generation if nothing was done about the global food crisis. So how could humanity survive to create a wormhole, if we need to go into the wormhole first to survive this pending apocalypse?
Unless this is a human race from a parallel universe in which the global famine never took place and humanity was allowed to survive and evolve into said fifth dimensional beings who could traverse space, time and dimensions to help out a parallel universe human race. Acceptable, but not mentioned by movie as a possible explanation.
2. The wormhole appears near Saturn, even though it would be WAY more convenient if it had opened somewhere next to the moon, or in orbit of earth, or perhaps even two feet about the ground on earth itself. If it was really created by human beings from the future, then it’s kind of a dick move on their end to put it waaaay out in space where it’s so hard to get to.
Unless off course these are the same jerks who litter monoliths in that general area..
3. The astronauts who first went out to explore the twelve disciples – Um, I mean, planets – are said to have enough supplies to survive two years. Ten, if they use their hypersleep devices. But after losing twenty three years on the planet that orbits the black hole, Cooper and his crew still find Matt Damon alive and well in his hypersleep pod.
4. After entering the singularity, Cooper enters a miraculous space-time warp that grants him the ability to send messages back into the past to his daughter. He knocks down books, causes gravity ripples, and encodes a watch with a hidden message; basically replaying the phenomena that took place in the past as he experienced it himself. But if that past already took place, then why would he need to do any of this anyway? Those phenomena directly lead to him finding NASA, getting on a space ship, and finally entering the singularity. The movie insinuates that if he never sent any messages, then he would not wind up in the singularity. But he’s already there so even if he just sat there for eternity doing nothing he wouldn’t undo the fact that he *is* there.
It’s possible that he isn’t altering his own past of course, but some parallel universe version of his daughter. But again, the movie makes no mention of parallels. Even so, what are the odds that this alternative Cooper and Murph would act the *exact* same way? Or better yet, why would he care? It’s not like he would be saving his own earth, he’d just be influencing a parallel world, which makes me wonder why the fifth dimensional beings would need a guy from this universe to influence the events in a parallel universe… And if that’s the case, how many parallel worlds would Cooper go on to save before he got bored? I suppose all of them, since there are infinite universes out there for him to save, but with infinite time on his hands it would simple be a matter of X-ing them off one by one.
Also, let’s say he is really altering his own past, sending a message to his past self from outside of time, and causing that past self to go to the wormhole and into the singularity, then his past self should immediately show up (since Cooper 1 is sitting outside of time). In fact, if he’s stuck in this loop of influencing the past to end up in the singularity, then an infinite amount of Coopers should be appearing inside the singularity at all times.
5. After sending the message into the past, he sees unfolding exactly as he witnessed them from him own timeline, suggesting that free will never comes into play. I doubt that the story is trying to say this, because then, there would hardly be any story unless that was the grand morale of it all, and that’s just not what the movie was about. Also, I can easily imagine how some people believe that we don’t have free will, but to suggest that even fifth dimensional beings have no free will? They are like gods in that universe, which would mean that even god had no free will in creating the universe, and again, the movie is really not about that.
6. After sending the message into the past that directly lead to his departure from earth, Cooper screams at his past self: “Don’t go!”. So why did you send that message then? Dumbass.
7. After spending the equivalent of a century to get back to his daughter, he chats with her for an entire minute and then takes off to find Brand because apparently he’s into her, even though she clearly said she was into some other guy which we are reminded off in the scene where she buries his body. I guess Cooper assumes that she got over this other dude just as quickly as he himself got over losing a freaking century of quality time with his daughter.
8. Seeing that the human race survived at the end of the movie, it’s safe to assume that Murph received her fathers’ message and finished the anti-gravity equation that allowed everyone to escape earth and settle on one of the habitable planets on the other side of the wormhole. Everyone from earth would have them gotten on their new spaceships and terraformed the crap out of these new planets A.S.A.P, years before time-warp Cooper and Brand get back into the picture. Brand should have arrived at her planet, finding a fully settled culture of billions, considering that her time-line runs parallel to Coopers’.
9. Hey fifth-dimensional beings. You have the ability to bend time and space and stuff. How about send me back to the past with my robot here, so that we can pass on the missing part of the anti-gravity formula to the scientists and I can get back to hang out with my family.
10. Before the crew sets off to the planet orbiting the black hole, they discuss the drawback of a visit, being that one hour equals seven earth years. But when they finally set foot on the planet, they act surprised to realize that the astronaut from the previous mission had landed (and died) there no more then a few minutes ago (relatively speaking).
They then proceed to get back to their ship as fast/slow as possible, as soon as they realize that the “mountains” in the background are really super huge waves, which is a little detail they somehow missed while making their descent.
One of the crew mates dies because, reasons.
Brand and Cooper find that there’s some issue with the ships’ engine preventing them to leave and say that “this’ll cost us decades”, even though they then proceed to have a two or three minute talk before being on their way.
When the next wave approaches, Cooper turns on the engines that were not going to start a few minutes ago but work now.. and takes the ship into space. Which, by the way is really weird on its own, because they needed a big-ass rocket to leave the earth, but going forward, they only need their little shuttle to break a planets’ gravity.
They then return to their station, finding it in tip-top shape, even though the guy who they left there had twenty three years to go completely insane and completely trash the whole place. Instead, he grew a short beard. I mean, he’s not even mad when he sees them. He -almost comically- just says “I’ve waited twenty three years.” I tell you, if someone stood me up for that long… Well, first of all, I’d have forgotten their names and faces, which means my first words would likely be “who are you??”, quickly followed by “Twenty three years you bastards!!”.
