Your thought experiment edit
Your thought experiment would be an appropriate question for our Science Reference desk. But before you post it there, let me address one underlying misunderstanding: The question "where - along the original length of the ruler - would the near zero length mass of atoms congregate?" does not make sense, not even in Newtonian mechanics. Consider the following thought (or real) experiment: Inflate a balloon. Let it fly. As it flies, it contracts. (To keep it simple and similar to your question, we may want to assume the balloon has the shape of a ruler and contracts evenly.) Towards which point along the original length of the balloon does it contract? This question might make sense if we had an absolute coordinate system - which we don't have, per Galilean relativity. — Sebastian 19:50, 31 December 2009 (UTC)
