`  :::: It is about improving the article. The subsection's title promises to clarify whether length contraction is real (physical shortening of an object) or just apparent shortening. Then Einstein is quoted as affirming that changes as seen from different frames are real changes. So, as per my obvious example, length contraction must claim that Earth's diameter ``really`` contracts in thousands of different ways, depending on the velocity and direction of thousands of different observers, i.e., that its diameter ``really is`` 4000 miles as measured from the frame approaching at .866c. Whatever applies to the length of a rod must also apply to the length of Earth's diameter. No ``straw man`` about it. Do not continue to mistake such criticism for ignorance.   `
