<< Are there two sets of Dragon balls?  If not, why did they scatter all over
 the universe instead of all over the earth in DragonBall GT?  I am writing

There are two sets of Dragon Balls. The orange star balls and the black star
balls.
The orange star balls go over the earth and the black star go over the
universe
