Tests of special relativity refer to experiments and observations designed to verify the predictions made by Albert Einstein's theory of special relativity, which was published in 1905. Special relativity fundamentally changed our understanding of space and time, introducing concepts such as the constancy of the speed of light, time dilation, length contraction, and the equivalence of mass and energy (E=mc²).
