Relative speeds reaching c?? Just an idea.... Suppose i am travelling at the speed of slightly more than c/2 with respect to ground and there is a stationary plane mirror in which i can view myself approaching the mirror. Now won't my relative speed with respect to my image be more than c?? Since time dilation would be equal for me and my image..... so can i violate the law that speed of c cannot be attained?? Similarly if i am travelling at slightly more than c/2 and pass someone going in the opposite direction at the same speed as me.... again will i view him going at speed over c?? I know attaining speed of c/2 is highly improbable..... but if this is overlooked.... is this hypothesis possible??
