The first of these experiments was carried out by Ives and Stilwell in (1938) and although the accuracy of this experiment has since been questioned,[citation needed] many other longitudinal tests have been performed since with much higher precision [1],[2]. These usually claim greater certainty than Ives-Stilwell, but also tend to be more complicated.
