Question: How can hyperspace work without hitting or going through stars? The Spacecrafts don't turn, so how does it work? This is a problem with most movies with a hyper drive scene.
Question: Is Han Solo brain-dead, or does he have the biggest cojones in the galaxy? From what we see of Greedo trying to kill him, there really isn't much explanation for why he is found screwing around in a bar on the home planet of the mobster who has it in for him. He couldn't have possibly known that the special edition scene with Jabba could go so well in his favor. I can't think of an explanation.
Answer: Han is still under the impression that he can pay Jabba off, and, as his meeting with Jabba implies, the Hutt is still willing to cut him a little slack, so he's not actually wrong. As such, he needs work - the cantina is one of the best places to find opportunities to get money - as, indeed, he does, by meeting Obi-wan and Luke.

Question: When Obi-Wan tells Luke about Darth Vader murdering his father, Luke doesn't seem to have heard of Vader before. But he knows about the rebellion and wants to go to the Imperial Academy (so he can defect later). Shouldn't he know who Vader is?
Answer: For most of his early life, Luke lived a simple, rustic life. His aunt and uncle knew his parentage and no doubt suppressed information about the Empire from him. Luke is naive and still has a limited and generalized knowledge of the rebellion, most of which was gleaned from talking to friends. He has little awareness of who the key players are.
raywestAnswer: Remember that Luke was hidden on Tatooine as a baby, and Obiwan also went into hiding there, presumably as a protector to keep Luke's very existence a secret from Darth Vader. It could be that Obiwan remotely exercised Jedi mind-tricks on Luke throughout his young life to block any curiosity about Vader.
Charles Austin MillerQuestion: Who has higher authority, Vader, or Admiral Tarkin? It seems like they have equal authority over the galactic empire. Shouldn't Vader have authority over Tarkin? Vader is supposed to be the Emperor's second in command.
Answer: Vader isn't second in command of the Empire; he's the Emperor's apprentice, albeit a very powerful one. Vader isn't in the "chain of command" so to speak. He's more of a tool the Emperor uses.
Answer: Tarkin is the commander of the death star and thus the supreme leader of the Empire's armed forces. Vader is more of a specialist, high in rank but not in charge of the military by himself, but probably successor of the emperor unlike Tarkin. You could see it as Tarkin being Heinrich Himmler and Vader being Joseph Goebbels in terms of hierarchy.
lionheadQuestion: Has there ever been any sort of canonical discussion about the morality of droid treatment in any Star Wars titles? They're intelligent/sentient, are treated well by most people, even like friends/pets by some. And yet they also seem to casually get their minds wiped, or if they're destroyed many people shrug rather than mourn. Tools to some, valued comrades to others, it's just a bit all over the place. Idle thought really.
Jon SandysChosen answer: Nobody in the Star Wars universe, except on rare occasions, has shown sympathy towards a droid or any AI. Even though these robots learn, they don't really evolve beyond their programming so they aren't considered "alive" (unlike in other fiction like Wall-E), not even by the most sentimental of people. Organic beings develop attachments to droids, but mostly towards their usefulness, not because they like their personality, not even Luke Skywalker towards R2 or Poe towards BB-8. If they are destroyed, too bad. Memory wiping doesn't remove the droid's original programming either, and their way of talking and manners stay.
lionheadIn Episode 2, Obi-Wan makes the offhanded comment "Well, if droids could think there'd be none of us here", implying that droids do not actually possess artificial intelligence. R2-D2 seems to be a particularly unusual droid in that he is uncommonly resilient and steadfast, which makes his allies quite fond of him. Poe and BB-8 appear to have a bond that goes beyond simply being attached to the droid's usefulness, but like you say that appears to be a unique case.
BaconIsMyBFFJust because he said that doesn't mean they didn't have AI. They think for themselves, so they have AI. Just not as advanced as in other fiction.
lionheadThe point is raised again later in the film when the cloners state that unlike droids, clones can think for themselves.
BaconIsMyBFFAnswer: Not in the films, but several of the books removed from canon by Disney mentioned a "droids' rights movement" that decried memory wipes and other dismissals of sentience. https://starwars.fandom.com/wiki/Droid_rights_ (movement).
LorgSkyegonSolo, which is canon, features a subplot about droid's rights. So not everything has been scrubbed regarding this topic.
BaconIsMyBFFQuestion: If you have the film on iTunes, or Blu ray, it has descriptive audio. Turn on the descriptive audio, and go to the beginning of the credits. It says" this has been described by miles [somebody]." How do you spell his last name?
Answer: It's Miles Neff.
Answer: Because a computer calculates a path where the ship will not collide with anything. Han Solo even says this to Luke about "ending his trip real quick." This is why it's possible.
