Three specific examples of the twin paradox are provided in which the system is completely symmetric; consequently the existing explanations are not able to resolve the paradox. %K Twin Paradox %K Asymmetry %K Acceleration %K Relativity %K Lorentz Transformation %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=111692
