The "nothing faster than light" thing has been repeated so much that people just take it verboten. Its actually not specifically true. Electromagnetic fields can only propagate through a vacuum at roughly a max of 299,792,458m/s. Its super easy to slow light down. Sunlight does not travel at its max speed when it hits the ground. Its been slowed down by the atmosphere. The one thing that most definitely can, and has travelled faster than 299,792,458m/s is space itself. Indeed, space is expanding as we speak. You only have to worry about causality and referential frame violations if you physically are trying to move at high velocity. Wormholes are shortcuts through points in space. Its a different part of physics that doesn't get into the whole "faster than light" thing. Just sidesteps around it.
