Thanks for these links and LOTS of readings

3 remarks to the "center problem".
1) If just watching the celestial day- and night rhythms, our ancestors naturally would believe the Earth to be the center.
2) If watching the annual appearance of the changing zodiacal star constellations and their helical rising, they MAYBE would have deduced the Sun to be the center.
3) If including a knowledge from their Stories of Creation, they would have taken the galactic center to be their prime one.
But then again: We now know of galactic clusters and super clusters and some cosmologists have the conviction of a central
Great Attractor - and at the same time call this an anomaly. And they even have such an unusual "gravitational thing" as a
"Dipole Repeller" in this cosmological picture.
IMO this would request an initial spinning momentum if and when talking of a possible Big Bang model. Where should this spinning momentum come from?
In a first glance, this is somewhat contra intuitive too me as galaxies in the observable Universe have both
clockwise and anti-clockwise spins. seen from our perspective. How could this be if the entire Universe had one direction spinning at a beginning?
