Special relativity describes the relationship between measurements made 
in one frame and the corresponding measurements made in another frame. 
In general, the results vary in different frames, and where a result 
comes from measuring a length, there is a tendency for the popular 
science media to describe the lower result as being a contraction.

But it really isn't, and there are no physical changes.

As I said, you need to study the math to grasp it.

For such an important theory, the math is very straight forward (compare 
and contrast with quantum mechanics). There's really no excuse for not 
studying it before expounding on it.
