Does Acceleration affect Lorentz contraction? Suppose their was a Circle spinning around its center then its outer edges would decrease in length. looking somewhat similar to a saw blade or something. This doesn't make sense though because then then object would change shape depending on what frame of reference you are looking at. However all the examples of Lorentz contraction i have seen involve objects moving in a straight line. Circular motion could be viewed as an object constantly accelerating around a point, which is what lead me to the question, does acceleration affect Lorentz contraction.
