I am able to understand the mechanics (minus the math, I'm not a physicist) of gravity accordin...

If the universe is expanding spacetime faster than light (FTL), is FTL travel no longer completely impossible? Do not care about energy requirements or needing new tech, just if it is NOT physically impossible given this natural, actual observation/phenomena.
