[Dr. Beckenstein]

In short, because Star Wars is a cinematic universe, where things like real-world science, logic and common sense always will play the second fiddle to the rule of cool.

And it good this way.

Because when people went to the cinema, they want to see Death Stars, space battles with noises, lightsaber fights etc. Not boring realism.

If you want to introduce staff like this in your campaign, feel free to do it. Nobody will try to stop you, but the end result will look very different from the "real" Star Wars.
