I get the theory of special relativity, it is the logical conclusion drawn from the two facts that: a) the laws of physics are the same in all reference frames b) the speed of light is constant in all reference frames what I dont get is why einstein thought the speed of light was constant in all reference frames. What proof of that is there even now? I know maxwell came up with c which is like 1/(m0*e0) or something which kinda suggests it but why couldnt that just be the initial velocity of light if the emitter was at rest with the "global reference frame". Also, Im not convinced that theory is true. I mean, Ive heard of all these experiments "proving" general and special relativity, but Ive never seen any documentation of any or any real numbers. Ive searched to... Can someone please give me some good links before I start talking about a giant physics conspiracy?
