How does not knowing what dark energy is open the possibility of FTL travel? I think if you've never seen anything move faster than light under any circumstances, from subatomic scales on up, "impossible" is a pretty reasonable conclusion. And while general relativity is incomplete, it's also the most robust scientific theory we've got, with a perfect record of predicting outcomes at macro scale. And it tells us that FTL is out of the question.We don't know what gravity is, we don't know what time is, we don't know what makes consciousness, and on it goes. Discussing what's "possible" is, based on current knowledge, the height of human arrogance and hubris.
I'm also vaguely hopeful that a ToE would give us a realistic path to warp drives or something, but I can't say it's a very reasonable hope.
