I'm new to physics, so I'm sorry if this is a dumb question. If a string cannot be point like, it has measurable spatial dimensions, then it must have mass. Well if a string was vibrating at the resonant frequency of a photon, and at rest it must have mass and therefore a nonzero rest mass. This is obviously wrong because according to SR a photon must have 0 rest mass. what am I getting wrong here?
Thanks
