Once again... We don’t know everything there is about science- mathematically it IS possible to do faster than light travel.
From ancient records it is obvious SOMEONE was here that they talked about coming “from the heavens”
And Bob Lazar saw their gravity propulsion systems, and I believe him (seriously, I do)
"Mathematically" means nothing. The question is, is this physically possible. The answer to that question is no.
Taking E=mc² as a staring point, could you please elucidate that statement?
