I read somewhere that the FE theory includes something called 'dark energy' which accelerates the earth upwards causing everything to stay on earth. Is this true? If so, can someone explain it a little more? Also, where are we accelerating upwards to? Where is the proof for this type of energy?

Polaris is the only star on course. If we are getting any closer? No.

How did you measure our distance to Polaris? Considering some stars are getting closer and others are moving away, I don't see Polaris' movement as being particularly important overall.
OP, I think the general rule of thought is that, according to FEH, the Earth has to be accelerating upwards. They needed an energy source for this to happen, so dark energy! (it sounds sciencey and legit)
