1- This fall into the "chosen one" category, yes I know it doesn't make much sense but as no one was supposed to find that base and the fact that his professor was heading the project, well made him the "Neo" of this movie.
2- I'm with you on this one, but I think they said gravity was different on those planets, assuming is way less than earth they could make it.
3- Totally agree, they should had at least a room or something on the edge of the spinning thing to get gravity.
4- I have two explanations for this: a) The wormhole was vacuuming everything hence getting the planets closer. b) They discovered that Super Cruise was a feature on their ship

5- I guess this was to make the movie more "epic" as going into another galaxy.
6- Agree with you, but maybe they went to the Prometheus school of science.
7- See point 6 but this time it was the writers.
8- I'll summarize this one "it's a movie".
9- Here I thought the movie was going to end in the old time paradox, were what happened already happened and cannot be changed and we were just seeing it from another perspective, reason why I did not liked the ending.
10- Again scientists in this movie went to the Prometheus school of science.
The gravity thing I did not understand either, maybe I'll have to watch it again, their accent was sometimes weird and English is not my native language
