It is well known that constancy of speed of light is the absolute foundation for this theory to be constructed. If light cannot maintain its constancy on speed, it must be of interest to know what is left to support the validity of this theory. While relativity has equations to forbid the appearance of speed that exceeds the speed of light in nature, the same equations either pushes some speed to exceeding such a speed limit or imposes c/2 as another speed limit. Shouldn't we feel irresistible to ask: Why the key points have been so well camouflaged in the derivation of this theory that it can escape the fine-combing done by so many scientists for more than a century? This author believes it is time for us to answer this question. In presenting this review, this author never ceases to wish some people would come forward to help this author realizing how mistakenly this author has been but relativity's integrity is left unchallengeable. Immeasurable thanks to the people who would spend time to examine this paper, or even to correct this author if he would like to do so, are hereby given in advance.
