The movements of the Stars
The stars are not fixed in space but all have a local orbit on their own. There is no expansion of the universe needed and most probably all stars have at least a binary companion to explain their local orbit.
In a geo-heliocentric model of the universe, the proposed 300 million km Earth travels every 6 months, is no longer the base of the measurements. Therefore the closest stars lie just beyond the planets, meaning the size of the VISIBLE universe becomes realistic again.
Just like a torch light shining at 10 meter, differs from a torch light shining at 1 km, at one moment in time the light is no longer visible. The flash light loses energy. Just like the light as spread by stars are losing energy.
This might also explains the visible red shift: the further and dimmer the stars, the redder the shift. Beyond a certain point nothing can be seen anymore.
