GOLF BALL....without dimples..?

The dimples on a golf ball are extremely important and very complicated stuff. Basically provides the sphere with a less and more constant drag coefficient then that of a smooth sphere. The drag caused by friction, but more importantly the drag is caused by the separation of the air flow behind the ball, known as a pressure drag. On a smooth sphere laminar flow separates very easily. However on a sphere with dimples the turbulent flow doesn't separate so easily and is delayed.

The turbulent flow has more energy than the laminar flow and thus, the flow stays attached longer. Dimples cause the Reynolds number to decrease thus the flow becomes more turbulent at a lower velocity then a smooth sphere. This causes the flow to remain attached longer on a dimpled sphere then a smooth sphere which reduces the drag.

Dimples help the ball to fly further (aerodynamics) but no dimples would help it roll straighter when putting. There are some balls with about every 7th dimple filled in to still carry pretty well, but is easier to putt

One company, Caeser Golf, produces a no-dimple golf ball. It doesn't go very far but doesn't slice either

my guess is that if there were no dimples it wouldnt go as far and imposible to hit straight

well it will have no back spin....and your ability to hit a fade or draw would be limited and it would be very hard to slice or hook
