Impossible

"No. That's not true. That's impossible!"

- Luke being a whiny idiot

Impossible refers to a thought or idea that is incapable of being true or an action incapable of being done or performed. Whenever somebody says something's impossible, it should always be trusted. Except for that one time, when Darth Vader told Luke he was his father, and Luke said it was impossible but he really was. And that one time where Goldenrod told Han Solo that he couldn't navigate through the asteroid field without getting destroyed, but he did. And that other time when fake Wedge said it was impossible to shoot proton torpedoes down the 2 meter exhaust port, but Luke did it. And that other time when Yoda said it was impossible to see the future, but somehow... okay fine I'll shut up.
