Says, so confidently, the member of a species who hasn't yet discovered a form of FTL travel.

The general assumption is that any visitor from outside the solar system has found a unique solution to this enormous problem beyond our current level of understanding.

Says confidently someone who has studied physics enough to get a basic understanding of relativity.

I'm not very good at physics, but I know enough to state confidently that FTL will never be possible. Anyone who has studied physics will agree with me: while there is a lot we don't know, every possible answer to them still needs to fit with what we already know and you can't explain several things we know while also allowing for FTL.

We still can't explain the big bang, yet here we are. Just because something can't be explained with our current models or understanding, doesn't mean it's forever impossible.

what we cannot explain must still obey the rules we have figured out. Much as you might wish otherwise.

I have one thought on FTL travel. Creation of a “naked singularity” by spinning a black hole fast enough to counter the forces holding it together. However the singularity will remain incompatible with our universe, and will then spread at the speed of causality popping, destroying everything in its path. But within that new universe, it might be possible.
