The way I think I understand it, even if we had some “element 0” like in mass effect to keep a starship from reaching unmanageable mass while accelerating, faster than light travel still wouldn’t be possible because you’d be violating causality somehow, but every explanation I’ve read on why leaves me bamboozled.

Because the faster you go the more energy it takes and it increases exponentially. Once you get very close to the speed of light the amount of energy required becomes several galaxies worth and if you somehow reached the speed of light you’d have infinite energy which isn’t possible. Another issue is that the faster you go through space the slower you go through time. At the speed of light you aren’t moving through time(photons don’t age or decay) so time for you would stop, going faster than that would technically make you go back in time which we beleive isn’t possible.(would need more than infinite energy)
