There are a few speculative ideas on faster than light travel. Such as worm holes, quantum tunneling, and super fluid vacuum theories.
Are they real in the sense that we can know how they can work today? Nope. But lots of ideas we take for granted today were “impossible” not that long ago. The fact that real physicists are even thinking about those possibilities could lead to something in the future.
