if everything, like all planets and stars are moving upwards, then that means that if you jump off the edge of the flat earth....that would have to mean you'd move upwards with it, you'd never fall behind cos you'd have to be pulled along with this "dark energy", right? so in this FE "theory", all bodies within the entire universe must be effected by this force, which means we wouldnt feel the "gravity" generated from the accelerating earth, because we ourselves would also have this force acting on us.
you know?
lol, if anyone would like to debate this, go ahead.
