1. How long was Luke training with Yoda? Ive heard everything from 7 days to 6 months. 2. In episode 6, could Luke have taken Palpatine if he decided to engage in lightsaber combat? He was so much older then Vader ive gotta figure the kid had a fighting chance. 3. Just how powerful WAS Luke at his peak? Ive heard a rumor that in the EU he was able to create/move/destroy (I cant recall which one) a black hole. Thats...God like!
