So while golfing, I noticed that the shadows of my golf balls looked like perfect ellipses. However, I thought about it, and this seems like a very sketch claim. If we consider the ground to be a perfectly flat plane, and the sun to be a point source infinitely far away, is the shadow created perfectly elliptical? Or is it slightly skewed away from the ball (personally this is my thought)? Or is this skew virtually 0.
