Geocentric Earth

[Jehanne]

This is just nonsense; take the Lagrangian challenge:

Lagrange Point Challenge

Just because there is no absolute reference point in space does not mean that all models are "true".

I think you misunderstand me, as supporting geocentrism as a viable theory of cosmology.  I'm not.

But it depends what you mean by "center."  Unless an actual center for the Universe is known (it isn't), you can arbitrarily call any point in space the center.  It's not a theory-- it's just a choice.

But choosing the Earth as your center point is a particularly poor choice, because then you have to mathematically account for all the myriad "movements" of the stars, of the sun, and of the moon.  At some point, a guy gets tired of shooting himself in the foot.

Geocentric models work great when you want to run a planetarium show; other than that, they have been falsified. No Ands, Ifs, Buts about that!
