Swiss Cheese Has Eyes, But Can't See
You would think we'd have this figured this out by now, but in the year 2015 we finally know what causes the holes in swiss cheese. The previously held idea was that the holes (also known as "eyes") in swiss cheese were caused by carbon dioxide given off by bacteria. However, the real reason is hay. Current theories suggest the holes are caused by microscopic hay particles in the milk used to make the cheese. The more hay particles, the more holes in the cheese. Just for the record, scientists cloned sheep 19 years before they figured out why swiss cheese has holes.
