The Alcubierre drive gets around this by bending the spacetime around a craft so that portion of space is moving and not the craft through space. And beyond tha

  Yes, I will happily concede that time travel and FTL is possible with wormholes. I would even buy into Novikov's self-consistency principle to avoid paradoxes. However, to manipulate spacetime like that, we'd have to control massive quantities of an never observed type of energy. Like, on the order of the mass of the galaxy, or at least solar masses. And constructing a wormhole between A and B will still take longer than light travels between the endpoints, so I'm not exactly holding my breath. The Alcubierre drive (assuming it's feasible) will still violate causality though, and the self-consistency principle does not apply, so I'm convinced that's a bust.

    Our prevailing theory of quantum mechanics is QFT which suggests that there aren’t actually any individual particles, but fields that experience excitations which act like individual particles. If we find that gravity is also just a field and gravitons are excitations within the field, who’s to say that perhaps every excitation in that field is entangled in some sort, and to create a traversable wormhole to the other end of the galaxy, we only need to impact the gravitons around us?
