Am I reading this wrong, or did you just say that Luke cut off Vader's hand? If you did, then I wonder what movie you saw; it didn't exactly happen that way.
Luke severed Vader's prosthetic hand in the final lightsaber battle before the Emperor.
Lets be honest here. Logic and the Greek Pantheon didn't exactly go hand in hand. The sanest of the bunch was Hades and that's saying something.
To the Greeks, all creatures were creations of the Gods. And yet all creatures have flaws. They saw this as either deliberate or unavoidable.
This is despite the fact they knew full well the Rebellion had stolen the plans and had time to study the plans which gave them access to full intimate knowledge of the Death Star's inner workings with the said flaw? Were they just crossing their fingers and hoping on that one?
As I pointed out earlier, the Empire didn't believe that the Death Star could be defeated. As far as they were concerned, there was no flaw in the design that the Rebels could exploit in the time they had. Even when his own tactical analysts warned him that there might well be a threat, Tarkin refused to believe it.
Sort of like you refuse to see things like this, even when they're pointed out to you multiple times.
But the Death Star could have all been avoided just by building a simple wall right in front of the vent. Or better yet, a laser turret or dozen with full access to whatever was coming down the vent?
Sure. If they'd noticed the problem, and if they'd thought it was serious enough, they could have fixed it.
And the Titanic could have had enough lifeboats, if the people who built had realized that its design was not, in fact, unsinkable. I'm not sure why this is so hard for you to understand.
Come to think of it, wasn't the laser on the Death Star somewhat redundant? A thing that size, all they'd have to do is get close enough to mess up the gravity of a Planet. Not as showy true bu cut have saved a little on the budget.
Um, no. Now we're getting to basic physics.
A) As a construction of humans, the Death Star was impossibly huge. On the scale of planets though it was still very small. It was described as comparable to a "small moon" - not even a large moon.
B) Unlike a moon, the Death Star was mostly hollow - all those barracks and detention cells and power plants and suchlike. Thus it had far less mass (and far less gravity) than a planetary body its size.
C) If it approached within the
Roche limit of a planetary body, the tidal forces would tear it apart.
Again, there actually is a logic to most of Star Wars, if you can set aside your prejudices and look at it.
Wouldn't the resources have been better spent expanding the Fleet itself thus making the Empire's Military more flexible and easier to deal with threats as opposed to making a gamble on a cumbersome weapon that can only be in one place at one time?
Arguably. However the military design philosophy of the Empire tended toward Bigger Is Better. That's why they moved to replace the perfectly serviceable Star Destroyer with the much larger Super Star Destroyer. The Empire used intimidation as a primary weapon, and the Death Star was simply the culmination of that trend: one ship that could destroy a planet.
This isn't unique to the Empire. Armies throughout history have tried to make one big weapon that could rule all battles against their enemies, even though it could be in only one place at a time. Look into the history of the
Bismarck for an example.
Didn't the Rebellion spend some time after the Death Star getting beaten across the Galaxy before what happened on Endor?
Yes - their fortunes took a turn for the worse after the Battle of Yavin. However the Imperial fleet had not been able to defeat them for 20 years, and it couldn't defeat them then. It was simply one end of the back and forth see-saw that had defined the whole war against the Empire. Had the Emperor believed that his fleet alone could beat the Rebels, he wouldn't have commissioned the construction of the second Death Star.
Where were these Dark Shrines exactly? Unless they were like that place where Luke had to fight himself. Which Yoda actually had to guide him to in the first place...
Yep, that was one of them. And Yoda did show him where it was, but there's no reason to suppose that a curious boy couldn't have found it on his own, given time. And Yoda had to stick reasonably close to such places, because they were what camouflaged him from force detection by Vader or Palpatine.
So, yeah...predator-laced jungle planet infested with the dark side does not make a good spot to raise a baby by oneself.
But Vader and the Emperor know he's a threat, they'd have been searching for him. And the fact he doesn't even change his last name really hurts his chance of staying incognito.
Assuming that "Kenobi" is an unusual last name, yes. However it's clear from the context of the film that Luke has no special associations with that name. Clearly he's never heard of any badly wanted fugitive named Kenobi.
Lots of people on Tattooine are wanted by the Empire. That's why many of them go there. For that reason most of them are just as happy to stay away from Imperial attention, and people don't ask nosy questions.
From the point of view of the Empire, the Jedi are a settled matter. Even if they suspected that Kenobi had survived it would be in their interest to pretend that he had not. Putting out an all-points bulletin would just let people know that there were still Jedi around, which the Empire preferred they not believe. And the longer they went without hearing anything from Kenobi, the less likely it seemed that he was still alive.
