Create from nothingness?
So I was reading Dark Rendezvous the other day, and this quote got me wondering-
“I want …” Yoda held up the flower in his hand and took another sniff. “I want a rose.”
“Be serious,” Dooku said impatiently.
“Serious am I!” Yoda cried. He bounced to his feet. Standing on the desktop, he was almost as tall as Dooku. He held the flower imperiously toward his former pupil. “Another rose, make for me!”
“The dark side springs from the heart,” Dooku said. “It isn’t a handbook for cheap conjuror’s tricks.”
“But like this trick, do I!” Yoda said. “The trick that brings the flower from the ground. The trick that sets the sun on fire.”
“The Force is not magic. I can’t create a flower out of thin air. Nobody can—not you, not the Lord of the Sith.”
Dooku basically states that it is impossible to create something from nothing- this is apparently beyond any Jedi or Sith that Dooku knows of. So my question- is there anyone in the mythos who CAN do so? Legends or cannon is fine.
