This thing bothers me a little. In the end of Episode III, Darth Sidious and Darth Vader are standing on the bridge of a Star Destroyer, and watching the construction of the Death Star.
Just look at it. It looks like the Death Star was constructed since the end of Ep 2 or the beginning of Ep 3. If the death star wasn't constructed since Ep 3 then how could they build it so quickly? If it was constructed since Ep 3 then how could Palpatine hide it from the jedi?
