OK, I don't feel like getting lost in the wookiepedia again so here's my question: At the end of ep 3 the emperor shows Vader the beginning of the Death Star. Yet in ep 4 Luke is roughly 17-19, and it still isn't finished, so it takes roughly 20 years to build the first one. Why is the second one finished much sooner?

Here's another thing, most of us have grown up with the movies our entire lives so we've never really thought about it, but "the death star" is a really lame name.
