I do not believe the Special theory of relativity is in correct, however the question did come up in class the other day. If some people do believe it to be incorrect, than what are some of these theories as to why it is in correct? I was just wondering and curious about the whole subject. I did infact read somewhere that some scientists have a theory that the speed of light has actually slowed down over billions of years. what are some other theories as to why Speical Relativity is incorrect ?
