Incredible Constant Speed Of Light Debunked 2023. And since both $\epsilon_{0}$ and $\mu_{0}$ are constant, that means that $\frac{1}{\sqrt{\epsilon_{0}\mu_{0}}}$ is also a constant. The speed of light is constant.

Web in the famous relativity equation, e = mc 2, the speed of light (c) serves as a constant of proportionality, linking the formerly disparate concepts of mass (m) and energy (e). Morley at what is now case. We have done two observer studies which demonstrate time dilation.
