"The Universe is homogeneous and isotropic on large-scales"
As can be seen by the position of extragalactic radio-sources

Cosmological Principle
"The Universe is homogeneous and isotropic on large-scales"
As can be seen by the 2-point correlation function of galaxies, which are clustered
in scales of few x h-1 Mpc.
Other LSS scales: supercluster associations ~ 100 h-1 Mpc
filaments ~ 100 ­250 h-1 Mpc
voids ~ 60 h-1 Mpc
There is a characteristic scale 300 h-1 Mpc ! l ! cH0
