The solar system moves around the center of our home galaxy and this 
galaxy around the center of our local super-cluster and that around what 
only heaven knows.

So: everything moves!

BUT: we could use a simple trick and stop motion for at least the observer.


This would make 'at rest' 'relative' and we could say, that all 
observers are of equal rights, hence all observers are at rest. But they 
are only at rest for themselves, while for any other they move.

This means essentially the same thing: everything moves.

That's why the universe cannot have a center (because that center would 
not move).

Also the so called 'big-bang' must be 'relative'.

This sounds strange and unsatisfying. But I don't think so, because it 
is actually much easier to understand than current standard cosmology.
