Flat Earth Debate / Re: What direction is FE travelling in ...

Couldn't a flat earth go around in a circle? That way it's still constantly accelerating while not having to change speed. This sounds more likely due to the fact that the earth can't accelerate to the speed of light. This would also give centrifugal force to be observed as gravity.Actually, I think that in this model, the centripetal force would act along the radius, directed to the center of the circle, the angle of which would vary depending on where you stood on the FE. That is, the direction gravity is pulling you would vary depending on where you stood on the earth. Of course, you could probably account for this by making the circular path along which we're traveling sufficiently large compared to the earth...
But as to your comment that the speed of light somehow represents a barrier: it does not. SR states that no observer will ever measure an object as exceeding c, and we do not; the earth always has a velocity equal to zero, relative to us.
