QUESTION:
How can a star be born in the star Nebula and travel across space, or does
the Star Nebula move?

ANSWER from Vicki Balzano on May 3, 1996:
    Stars which are born within gas clouds (also known as nebulae) do in
fact move along with the gas clouds through space. You can try this
experiment to understand why this is so:
    You are traveling on the backseat of an automobile on the highway. You
are chewing gum and you blow an enormous bubble. Both you and the bubble are
inside the automobile. You will notice that the bubble gum will move along 
with you in the car. It does not stay back in the place it was created. (It
would smack you in the face.) It does not go flying down the highway by
itself. (Not unless you shoot it out of a cannon.) It continues on with the
basic motion of the car. 
   In this little experiment you can think of the car as a nebula and the 
bubble gum as the new star. The original gum matter was inside your mouth
travel at the same speed as the car. When the gum expanded to become a
bubble, it continued to travel at the same speed and direction as the car. A
star is created from matter contained inside the gas cloud (nebula), so it
travels along with the gas cloud just as the original matter did.
