hi
i have some troubles to understand something properly:
if oberserver A is not moving in his inertial frame and there is some observer B moving relatively to oberserver A with velocity V, then this observer B will measure a different(shorter) time from the one that is measured by observer A.
but one could also say that from B's inertial frame that B is not moving and he says: hey, observer A is moving with velocity -V, then the equation that gives me the time dilation would be the same, which would mean, that in this case observer A would measure a shorter time from the one that is measured by oberserver B, which seems to be a logical contradiction, where am i wrong?
