What if we discover FTL?

Even if you were able to travel faster than light that doesn't make it practical, even moving at 10% the speed of light leads to disaster! Why? Because collision with interstellar dust is going to be disastrous, the effects on your ship would be like that of an atomic bomb! So the real speed limit is not light or something that moves faster than light but the limits of your ship-to withstand a collision with dust...

I think FTL is mostly perceived as going trough wormholes - bending space.
So I am not sure if this involves any conventional travel trough space.
Ideally, wormholes have no dust or you dont need to go very fast trough them

As of yet, no one has observed an Einstein-Rosen bridge. And even if they did those models predict that the wormhole is unstable, meaning its useless for travel. So just having blackholes by themselves isn't sufficient for a wormhole to form and even if it did its useless for travel...
