> The assumption that FTL is impossible is predicated on our understanding of physical laws being complete. No, the assumption that FTL is impossible is based on it being impossible according to the very best evidence we have. It does not require a complete understanding of physical law to confidently state that the sun will rise in the east and a dropped ball will fall to the ground. > We don't actually know what's possible and what's not, only what we believe is possible given our current understanding of the universe. This will always be true. And we cannot say for certain that I am not a Boltzmann brain imagining a conversation with you. It means nothing. We have to work with what we are given because the alternative is to pretend that fantasy is reality. > Anyway, whether FTL is or isn't possible isn't the point of my post. The point is that if you assume aliens are basically like us except with warp drives then it's easy to come up with reasonable explanations for their behaviour. Fair, but what I'm saying is that that's an assumption on the order of "assume world leaders are actually disguised reptiles".
