Are you sure the church was wrong in their geocentric view?
Yes. Are you so subservient to church dogma that you are not willing to discard the geocentric worldveiw, even in the face of a mountain of evidence which you yourself can personally observe?
As I understand it without dark energy the Copernican model is falsified.
Then your understanding is deeply flawed. The Copernican model predates and is not, nor was it ever, dependant of dark energy. An education is a good thing, if for no other reason than it would prevent you from once again making a fool of yourself in the future.
That would leave the earth as the center of the universe
That's a false dichotomy, even if the Copernican model was flawed then that would not make geocentrism right by default, it's not and either/or issue. On top of that none of it has anything to do with the placement of the earth in the universe.
as the simplest explanation for the practical and mathematical understanding of the universe.
And how does one arrive at that conclusion without resorting to saying "Because the bible says so!"? You have sufficiently proved that you have neither practical or mathematical of the subject.
