"and i am sorry for my spelling i have always been bad at that"

No need to apologize. Your spelling choices just allowed an opportunity to have a little fun.

As an aerospace engineer I agree with Husker Fan.

A golf ball's dimples work like the vortex generators you can find on the upper surface of some aircraft's wings: they delay the separation of the boundary layer. On a wing the purpose is to maintain the lift or to keep the rudders effective. On a golf ball the purpose is to reduce the area of low pressure in the ball's wake (F_drag = delta_p * A). 'A' is smaller the later the boundary layer separates from the golf ball's surface.

Similar approaches for similar problem:
- boat tails on bullets
- necking the rear end of cars (CRX, Prius, Audi A2,...)

Different approach for similar problem:
- base bleed artillery shells: reduce the pressure difference

The only stupid question is an unasked one.

I'm an instructor. I can verify that your statement is incorrect.

T.Stahl,
I'm no aerospace engineer (Chem E. actually), but fluid mechanics is fluid mechanics.
