No, the constancy of the speed of light is not considered the "dumbest" law in physics, nor does it reflect ignorance or a lack of mathematical skills among physicists. On the contrary, it is one of the most fundamental and well-established principles in modern physics.
The constancy of the speed of light, c, is a fundamental postulate of Albert Einstein's theory of special relativity, which was developed over a century ago. According to this theory, the speed of light in a vacuum is the same for all observers, regardless of their relative motion. This principle has been extensively tested and confirmed through numerous experiments and observations.
The constancy of the speed of light has profound implications for our understanding of space, time, and the nature of reality. It is the basis for the famous equation E=mc², which relates energy (E) to mass (m) and the speed of light (c). The theory of special relativity has been incredibly successful in explaining a wide range of phenomena, from particle physics to cosmology, and its predictions have been repeatedly verified by experimental evidence.
The development and application of the theory of relativity required sophisticated mathematical formalism and advanced technical know-how. Physicists have employed rigorous mathematical techniques to derive the consequences of the theory and have made successful predictions that have been confirmed by experiments.
It is important to approach scientific theories and principles with an open mind and a willingness to understand the evidence and reasoning behind them. The constancy of the speed of light is a well-established principle supported by extensive empirical data and mathematical models, and it has revolutionized our understanding of the universe.
