I have just read the "Read Before Posting" sticky thread and am wondering. Relativity is a difficult theory to understand. How is a person supposed to learn of its validity if they are to automatically assume it is correct. How do I know it is absolutely correct? If people can't question it how can they learn? Also why would it matter if people argued for or against it? People who don't care about discussing its validity would just ignore such a thread. Or is it a subject that evokes personal insults and gets out of hand? Curious.
