Answer: People do not know vampires exist. The only thing known is through myths and legends, which no-one believes is real. The Volturi exist to act as a centralized, albeit loose, form of vampire government, that other vampires rely on to maintain their community. Any vampire breaking the laws or doing anything that exposes their world faces death, so it's unlikely any would violate the code of secrecy.

Answer: Considering how badly Jacob was injured during the battle with Victoria's vampire army in which his ribs were crushed, it is unlikely that the shape-shifting wolves are bullet proof.

Answer: Renesmee is not immortal, but will live an extraordinary long life and she will age slowly. It was never revealed if half-breeds can succumb to human ailments. Considering half-breeds are extremely rare, it's unlikely anyone knows.

Answer: It was never shown that the Cullens knew Jacob intended to kill Renesmee, only that he imprinted on her. Edward may have read his thoughts later, but kept this to himself after realizing Jacob would be forever bound to Renesmee as her protector.

Answer: It's unlikely they would do that. People may claim to have witnessed some strange event, but unless there's tangible rather than anecdotal evidence, this usually, over time, is dismissed. Killing the witnesses would garner unwanted attention on the Volturi.

Answer: The werewolves in the Twilight series are Quiliute Native Americans who mostly live on their reservation, have their own school, own legal system, etc. Being as it's a rather cloistered society, it would be easy for certain members to generally go unnoticed.

Answer: If, in the future, Renesmee left, Jacob would have to accept that, regardless of whether or not he was emotionally hurt by it. Because he imprinted on her, he is bound to abide by her needs and decisions.

Answer: They want Alice because she can see into the future, which would be a significant advantage to the Volturi. Aro destroys other covens, sparing the one member who has some special ability.

Answer: If by your question you are referring to all the complicated math formulas in the film, if Affleck and Damon themselves aren't well-versed in that area, then they would have hired an advisor for the film.

Answer: The answer is not necessarily one or the other-geniuses sometimes do extensive research. The answer also depends on how "genius" is defined/measured. I have read several online articles asserting that Matt's [and Ben's] IQ is "as high as 160." One definition of genius is having an IQ over 160, suggesting that maybe he is and maybe he isn't! (Real helpful, huh?) But there are different tests to measure IQ and IQ scores are only based on certain factors. Many experts assert that the really high IQ scores don't exist and/or there is no known test that can accurately measure very high IQs. I wondered about the math questions/proofs in the movie and don't know if they are real examples or if they are just a bunch of symbols slapped together to give the appearance of advanced mathematics. High IQ people tend to be eccentric, socially awkward, and/or loners who "do their own thing"; Matt does not appear to fit this profile. Psychologists, such as Matt's mom, have access to IQ tests.
