when you go into space,
and you head for the moon,
why doesn't the earth just fly away from you.
I believe it moves at 30 km/s. right?
and your not in an orbit?
so why doesn't it just fly away?

All of your rocket firing is just changing your speed RELATIVE to the earth...
Originally, while you were on the earth... you were moving at the same speed as it is... just because you left it does not mean that you will lose all of that speed...
and... I believe the earth is hurtling through space along with the expanding universe... at a much higher rate than 30 km/s

Because your inertia is imparted to you from the constant speed of the earth. If you are in space holding on to a rocket going a constant 300,000 mph and let go, you will continue right next to it forever. Only when something is ACCELERATING do you "fly away from it"

Because the moon is in the earth's gravitational pull and so is the space ship... so you are moving at the same speed
