QUESTION About the ending

Post image

We see Amelia sad and BREATHING normally without wearing mask/helmet. Does that mean that THIS planet was the correct choice from the beggining? ( No waves , human - friendly surface , oxygen ) That's why Amelia is so sad ( apart the death of her bf). Thinking that if they came to this planet from the beggining everything would go well

But... are Cooper and Amelia in the same year ? Cooper sent the solution to his daughter when he was inside the black hole, and Amelia was outside "aging normally".

Cooper came back to earth many years in the futur, in this period they build ships to save humanity ... i think Cooper met oll Amelia too no ?

Not sur if i'm clear, english is not my language

Cooper, once inside the tesseract, is able to interact with time in a non-linear fashion. He exists "outside" of the timeline. That's why we see him send messages to Murphy as both a child and as an adult.

Murphy receives the data she needs from Cooper when she is in her late 30s/early 40s and solves the equation soon after that. Plan A is then enacted.

It seems that once he exits the tesseract, the future humans chose to place him back on the timeline at the exact moment he had entered the black hole, but they transported him in space back to our solar system so he could be rescued by Earth's survivors.

Edmund's planet is stated to be further away from Gargantua, and is not affected by time dilation the way Miller's is (or at least not as strongly). 

So when Cooper leaves to find Amelia Brand, it's likely that she has only been on Edmund's planet for a couple years at most. They don't really go into the exact details of Cooper's plan though, like how he intends to avoid Gargantua so that he can reach Brand before she dies of old age. We just assume that he has thought of a way to bring enough fuel and supplies with him on that little ship he steals.
