So I've had many wonders about the whole unbreakable speed of light and what an army of scientists at CERN did. I already know they said it was a broken fiber optic cable or something else which caused that, but lets assume that what they were saying was true, then my questions arises: Does Einstein actually wrote an equation or formula that states that nothing can travel faster than the speed of light? If so, what is that formula? Is it a mathematical model? If something were to travel faster than the speed of light, in what would that affect us? I mean, the media says it would be horrible because a lot of experiments would be invalidated (but don't specify what kind or which experiments) Which theories, theorems, experiments or whatever would be affected by this? Are there other theories than the theory of relativity (which btw I have no idea what it is... sorry for my lack of knowledge)? Are there or there have been other scientists that oppose or have opposed Einstein? If there are or have been, who are they? I have no idea where this whole unbreakable speed comes from so I don't really understand the controversy behind it (I'm like in the void). All the media do is to make super compressed resumes which miss a lot of details and in the end its as if I hadn't read anything at all. I would like to learn more about it, but I don't know where to start, so I thought I'd start here asking these questions. This might be the most stupid post ever considering the other highly intelligent posts here, but I have to try (start with something).
