Get Real Posted over 3 years ago about speed of light Do not forget several issues: 1. Not all of the relativity theory is true and some was "proven" by wrong experiments. 2. It assumes that space and time are homogeneous and linear in nature. 3. Light speed is actually the speed of photons, which are massless. But yet, we can measure the impact (mv) of a light wave on a black/white plate (!?) 4. Einstein's E=mc^2 is only describing an approximation of how much potential inner kinetic energy is stored in the second level of material's structure (as we know it). Etc.
