In 2005, hard-hitting reporting by Scientific American magazine finally revealed why golf balls have dimples. What did they determine was the reason?

The article explained: "Dimples on a golf ball create a thin turbulent boundary layer of air that clings to the ball's surface. This allows the smoothly flowing air to follow the ball's surface a little farther around the back side of the ball, thereby decreasing the size of the wake."
